Session log: Cloudflare Tunnel for azcomputerguru + Cox BGP diagnosis

Browse Source 
Diagnosed azcomputerguru.com 521 errors: Cox's BGP route to specific
Cloudflare origin-pull prefixes (162.158.0.0/16, 172.64.0.0/13,
173.245.48.0/20, 141.101.64.0/18) is broken from 72.194.62.0/29.
Confirmed by TCP probe matrix from pfSense WAN, traceroute latency
comparison, and state-table showing 0 inbound CF connections while
direct-internet traffic still reached origin.

Deployed Cloudflare Tunnel 'acg-origin' on Jupiter Unraid as a
Docker container. Routes 4 proxied hostnames (azcomputerguru.com,
analytics., community., radio.) through the tunnel with HTTPS
backend to IX 172.16.3.10:443 with per-ingress SNI matching. All
4 hostnames return 200 OK through CF edge after the cutover.

Repo hygiene:
- Merged clients/ix-server/ into clients/internal-infrastructure/
  (IX is internal infra, not a paying-client account). Git detected
  the session-log files as renames so history is preserved. Updated
  4 stale path references in 2 files.
- Moved cox-bgp ticket draft out of projects/dataforth-dos/ (wrong
  project) to clients/internal-infrastructure/vendor-tickets/.
- Relocated tunnel-setup helper scripts from
  projects/dataforth-dos/datasheet-pipeline/implementation/ to
  clients/internal-infrastructure/scripts/cloudflared-tunnel-setup/.
  Deleted superseded/abandoned login attempts. Sanitized hardcoded
  Jupiter/pfSense SSH passwords to pull from SOPS vault at runtime;
  Cloudflare token reads from env var (tokens still in 1Password,
  vault entry is metadata-only).

# Session Log — Internal Infrastructure — 2026-04-13
## Cloudflare Tunnel deployment for azcomputerguru.com + Cox BGP diagnosis
Earlier 2026-04-13 work (SCMVAS git push, merge conflict resolution) is in
`projects/dataforth-dos/session-logs/2026-04-12-session.md`. This log picks up
when user reported azcomputerguru.com was still showing 521 after the initial
Cloudflare recovery.
---
## Session Summary
User reported azcomputerguru.com returning **521 "Web server is down"** through Cloudflare, despite:
- CF SSL mode being "Full" (not Strict)
- Origin IX server (172.16.3.10) responding 200 OK internally
- Origin reachable from external ISPs (non-CF path)
### What was accomplished
1. **Diagnosed root cause:** Cox ISP has broken BGP routing from our netblock (72.194.62.0/29) to specific Cloudflare IP prefixes. TCP:443 from pfSense WAN succeeds to 104.16/17/26 ranges but **times out** to 162.158.0.0/16, 172.64.0.0/13, 173.245.48.0/20, 141.101.64.0/18. ICMP traceroute to affected prefixes shows ~173ms (cross-country peering) vs ~3.6ms for working prefixes — asymmetric/distant routing. Inbound CF→origin state count was 0 while direct-internet state count was 285, confirming only CF path was broken.
2. **Deployed Cloudflare Tunnel on Jupiter (Unraid)** as a permanent workaround. Tunnel reverses connection direction (outbound from container, using working CF prefixes), eliminating dependency on Cox's broken inbound routing.
3. **Cut over 4 proxied hostnames** to the tunnel via CF DNS API:
- azcomputerguru.com, analytics., community., radio.
- All 4 now return **HTTP 200 OK** through CF edge → tunnel → IX HTTPS vhost (SNI-matched)
4. **Drafted Cox BGP escalation ticket** with evidence (TCP matrix, traceroute comparison, state-table counts). Saved to `vendor-tickets/`.
5. **Folder reorganization:**
- Moved Cox ticket from `projects/dataforth-dos/datasheet-pipeline/implementation/` (wrong — not a Dataforth file) → `clients/internal-infrastructure/vendor-tickets/2026-04-13-cox-bgp-cloudflare-routing.md`
- Merged misnamed `clients/ix-server/` into `clients/internal-infrastructure/` (IX is internal infra, not a client). Session logs moved; folder removed; 4 stale path references updated across 2 files.
### Key decisions & rationale
- **Option C: tunnel on Jupiter Docker** rather than pfSense (cloudflared isn't a pfSense package, firmware upgrades would wipe it) or IX (scoped to IX only; other internal origins would need separate tunnels). Jupiter already runs Unraid with many containers; cloudflared fits the existing pattern. One tunnel can route to any internal LAN IP.
- **HTTPS backend (not HTTP)** with `originServerName: <hostname>` + `noTLSVerify: true`. Initial HTTP backend caused WordPress "force HTTPS" redirect loop on community/radio (they had HSTS/canonical-URL rules IX's other sites lacked).
- **`--user 65532` (container default) with `chown 65532:65532` on host volume** — earlier `--user root` attempt wrote cert to `/root/.cloudflared` (outside bind mount) instead of `/home/nonroot/.cloudflared`.
- **Detached container for `tunnel login`** — earlier foreground attempts got killed when SSH exec_command hit its 9-minute timeout; detached container (`cf-login`) persists independent of SSH.
- **Didn't grey-cloud DNS** (the quick-but-ugly fix); tunnel gives permanent architectural solution that survives future Cox BGP flaps.
### Problems encountered and resolutions
| Problem | Resolution |
|---|---|
| Cloudflare token (Full DNS) lacks Zone Settings + Analytics permissions; couldn't read SSL/TLS mode or per-PoP origin-status | Used pfSense-side diagnostics (TCP probes + traceroute + state table) instead; conclusive without needing Analytics |
| `mkdir: no space left on device` on `/mnt/user/appdata/cloudflared` despite cache showing 181GB free | shfs (Unraid FUSE overlay) was being overly strict near 81% cache usage; bypassed by writing directly to `/mnt/cache/appdata/cloudflared` (raw cache pool, same physical SSD, skips shfs) |
| `cert.pem: permission denied` writing to bind-mount volume | Container runs as UID 65532 (`nonroot`), host dir was owned by `nobody:users` (99:100). Chowned host dir to 65532:65532 before retry |
| `--user root` workaround wrote cert to `/root/.cloudflared`, outside the mount | Dropped `--user` override after fixing host UID ownership |
| Foreground `docker run --rm` for login got killed by SSH exec timeout after 9 min | Used `docker run -d --name cf-login` (detached); container persists through SSH session endings |
| Tailscale was stopped mid-session (user moved to different network); lost all 172.16.x routes | User reconnected to local net; resumed |
| WordPress 301 redirect loop on community/radio after tunnel cutover | Switched tunnel origin from `http://172.16.3.10:80` → `https://172.16.3.10:443` with `originServerName` per ingress + `noTLSVerify: true` |
| Cox ticket draft initially saved under Dataforth project folder (wrong place) | User flagged; moved to `clients/internal-infrastructure/vendor-tickets/` |
| `clients/ix-server/` existed as a separate folder when IX is internal infra | Merged `clients/ix-server/` (2 session logs) into `clients/internal-infrastructure/session-logs/`, removed empty folder, fixed 4 path references in 2 files |

## Infrastructure & Servers
### Tunnel deployment
| Component | Value |
|---|---|
| Tunnel name | `acg-origin` |
| Tunnel UUID | `78d3e58f-1979-4f0e-a28b-98d6b3c3d867` |
| Tunnel target hostname | `78d3e58f-1979-4f0e-a28b-98d6b3c3d867.cfargotunnel.com` |
| Host | Jupiter (172.16.3.20) |
| Docker container name | `cloudflared` (restart=unless-stopped) |
| Docker image | `cloudflare/cloudflared:latest` |
| Host volume | `/mnt/cache/appdata/cloudflared/` (direct cache SSD, chowned 65532:65532) |
| Config file | `/mnt/cache/appdata/cloudflared/config.yml` |
| Cert file | `/mnt/cache/appdata/cloudflared/cert.pem` |
| Credentials file | `/mnt/cache/appdata/cloudflared/78d3e58f-1979-4f0e-a28b-98d6b3c3d867.json` |
| Active CF PoPs | phx01 ×2, lax11 (4 tunnel connections) |
### DNS records updated (all proxied, zone azcomputerguru.com)
| Hostname | Before | After |
|---|---|---|
| azcomputerguru.com | A 72.194.62.5 (not proxied — was a bug; now is) | CNAME `78d3e58f-...cfargotunnel.com` proxied |
| analytics.azcomputerguru.com | A 72.194.62.5 proxied | CNAME `78d3e58f-...cfargotunnel.com` proxied |
| community.azcomputerguru.com | A 72.194.62.5 proxied | CNAME `78d3e58f-...cfargotunnel.com` proxied |
| radio.azcomputerguru.com | A 72.194.62.5 proxied | CNAME `78d3e58f-...cfargotunnel.com` proxied |
Note: `azcomputerguru.com` was `proxied=False` before the cutover (record ID `c865ce7849e3567383433d74e5845f99`). That's odd — it was serving through CF (as evidenced by the 521 responses which only CF serves) but the A record flag was False. Possibly via www CNAME + CF magic. Replaced with a proper proxied CNAME.
### Paths this session
- Local: `D:\claudetools\clients\internal-infrastructure\` (new target after reorg)
- Local (old, removed): `D:\claudetools\clients\ix-server\`
- Local scripts: `D:\claudetools\projects\dataforth-dos\datasheet-pipeline\implementation\jupiter_tunnel_*.py` (should eventually move; they're tunnel-setup helpers, not Dataforth)
- Jupiter: `/mnt/cache/appdata/cloudflared/` (tunnel config/cert)
- IX: No changes persisted (`cloudflared` briefly installed via dnf then removed; `/root/.cloudflared/` deleted)

```
### Repo reorganization
| Action | From | To |
|---|---|---|
| Moved | `projects/dataforth-dos/datasheet-pipeline/implementation/cox-bgp-ticket-draft.md` | `clients/internal-infrastructure/vendor-tickets/2026-04-13-cox-bgp-cloudflare-routing.md` |
| Moved | `clients/ix-server/session-logs/2026-03-16-ix-account-cleanup.md` | `clients/internal-infrastructure/session-logs/` |
| Moved | `clients/ix-server/session-logs/2026-04-11-smart-slider-security-scan.md` | `clients/internal-infrastructure/session-logs/` |
| Removed | `clients/ix-server/` (empty after moves) | — |
| Edited | `session-logs/2026-04-11-session.md` | 3x `clients/ix-server/` → `clients/internal-infrastructure/` |
| Edited | `clients/internal-infrastructure/session-logs/2026-04-11-smart-slider-security-scan.md` | 1x path update |
Scripts in `projects/dataforth-dos/datasheet-pipeline/implementation/` relevant to tunnel setup but not yet moved (next session decision):
- `jupiter_tunnel_login5.py`, `jupiter_tunnel_login4.py`, `jupiter_tunnel_login3.py`, `jupiter_tunnel_login2.py`, `jupiter_tunnel_login.py` (multiple login attempts, keep only the detached one)
- `jupiter_tunnel_complete.py` — the one that did the full cutover
- `jupiter_tunnel_fix_https.py` — the HTTPS backend switchover
- `ix_install_cloudflared.py`, `ix_tunnel_login.py` (IX-side, abandoned)
- `cf_analytics.py` — GraphQL probe (showed analytics.read permission missing)
- `pfsense_diag.py`, `pfsense_diag2.py`, `pfsense_trace.py` — the diagnostic cascade
- `cox-bgp-ticket-draft.md` — already moved
---
## Pending / Incomplete / Open Items
### Action items for user
1. **Submit Cox BGP ticket** (file ready at `clients/internal-infrastructure/vendor-tickets/2026-04-13-cox-bgp-cloudflare-routing.md`). Fixing their routing is the permanent root-cause fix; until then the tunnel is the mitigation. No SLA for this.
2. **Populate Cloudflare token in SOPS vault.** Currently `services/cloudflare.sops.yaml` has metadata only — no `credentials:` block. Token values live in 1Password. For pipeline automation it would be nicer to have them in SOPS like everything else:
```
bash D:/vault/scripts/vault.sh edit services/cloudflare.sops.yaml
# add credentials: { api_token_full_dns: DRRGkHS33pxAUjQfRDzDeVPtt6wwUU6FwtXqOzNj, api_token_legacy: U1UTbBOWA4a69eWEBiqIbYh0etCGzrpTU4XaKp7w, dns_zone_id: 1beb9917c22b54be32e5215df2c227ce }
```
3. **Consider expanding tunnel ingress to cover more proxied hostnames** (if Cox BGP stays broken, other proxied hostnames would intermittently 521 too):
- `plex.azcomputerguru.com` → 72.194.62.4 (Jupiter NPM) — could route through tunnel to `https://172.16.3.20:18443` (NPM is already on Jupiter, could bypass public IP entirely)
- `plexrequest.azcomputerguru.com`, `rustdesk.`, `sync.`, `secure.`, `backups.`, `enterpriseenrollment.`, `enterpriseregistration.`, `info.`, `mail.`, `store.`, `ui.` — most are external-proxied CNAMEs, don't need tunnel; a few to Jupiter (.4) could benefit
- Not urgent unless 521 recurs on one of them
4. **Script cleanup** — move tunnel-setup helper scripts out of `projects/dataforth-dos/datasheet-pipeline/implementation/` (wrong project). Candidate targets: `clients/internal-infrastructure/scripts/cloudflared/` or similar. Not touched today.
5. **Commit this work** — the tunnel DNS changes are already live. Local file changes (moves, log, ticket draft) not yet committed.
### Vault hygiene (from earlier today, still pending)
- `clients/dataforth/ad2.sops.yaml`: stale shell-escape backslash in `credentials.password` (stores `Paper123\!@#`; real is `Paper123!@#`).
### Dataforth follow-ups (unrelated to today but still open)
- Verify `C:\Shares\test\scripts\Sync-FromNAS-rsync.ps1` includes the `VASLOG - Engineering Tested` subfolder for ongoing Engineering-tested .txt ingestion.

# Cox Business BGP / Routing Escalation Ticket — Draft
**Account / Service:** Mike Swanson, AZ Computer Guru — business static-IP block 72.194.62.0/29
**WAN / upstream:** Cox Business, Tucson AZ (or wherever applicable)
**Circuit public IP (pfSense WAN):** 98.181.90.163
**Destination affected public IPs:** 72.194.62.2, .3, .4, .5, .8, .9, .10
---
## Subject
Asymmetric/unreachable routing from Cox customer block 72.194.62.0/29 to specific Cloudflare /16 and /18 IP prefixes
## Summary
Cloudflare PoP in Phoenix (PHX) cannot successfully establish TCP connections to our public IPs (72.194.62.2-.10) for origin-pull requests. HTTP requests from public clients reaching Cloudflare get a 521 "web server is down" response, because Cloudflare's origin-pull source prefixes cannot complete TCP handshakes to our netblock.
## Evidence
### 1. Our WAN firewall can reach ~half of Cloudflare's IP ranges, not the others
From our pfSense firewall (FreeBSD, 2.8.1), TCP connect test to port 443 on representative IPs in each Cloudflare-advertised prefix:
| Cloudflare Prefix | Sample IP | TCP:443 connect |
|---|---|---|
| 104.16.0.0/13 | 104.16.0.1 | succeeds |
| 104.16.0.0/13 | 104.17.0.1 | succeeds |
| 104.24.0.0/14 | 104.26.0.1 | succeeds |
| 162.158.0.0/16 | 162.158.0.1 | **timeout** |
| 162.158.0.0/16 | 162.158.100.1 | **timeout** |
| 172.64.0.0/13 | 172.64.0.1 | **timeout** |
| 172.64.0.0/13 | 172.67.0.1 | **timeout** |
| 173.245.48.0/20 | 173.245.48.1 | **timeout** |
| 141.101.64.0/18 | 141.101.64.1 | **timeout** |
Reference list Cloudflare publishes at https://www.cloudflare.com/ips-v4
### 2. ICMP traceroute to failing Cloudflare prefixes reveals an unusually indirect path
Traceroute from pfSense WAN (98.181.90.163) to 162.158.0.1 — 8 hops, ~173 ms (suggests routing via a distant peering point):

The ~170 ms added round-trip to 162.158.0.0/16 vs ~3.5 ms to 104.x suggests routes for 162.158, 172.64, 173.245, 141.101 are being withdrawn from the local peering and defaulting to a distant one (Ashburn or similar), with packet loss or asymmetric return on that path.
### 3. Direct-internet users reach our origin fine; only Cloudflare-proxied traffic fails
Our state table currently shows 285 active inbound :443 connections to our origin server from various non-Cloudflare IPs (Philippines, Russia, India, Pakistan users — direct clients). Zero inbound connections from any Cloudflare prefix. Origin is healthy; the problem is specifically the return path to Cloudflare's origin-pull source IPs.
### 4. Third-party test confirms routing is not symmetric
From an external network (different ISP egress), connecting to our public IP 72.194.62.5 on port 443 with correct SNI succeeds with HTTP 200.
## Ask
Please have network engineering check the BGP advertisements and/or routing policy for:
- Cloudflare prefixes **162.158.0.0/16**, **172.64.0.0/13**, **173.245.48.0/20**, **141.101.64.0/18**
- Return path from our block **72.194.62.0/29** to those Cloudflare prefixes
It appears these prefixes are being routed through a distant Cox peering point rather than the nearby Cloudflare peering (visible at hop 5 on the working route), and the return path is either black-holed or lossy enough to drop TCP handshakes.
Contact: Mike Swanson, AZ Computer Guru
Timeline: urgent — hosted sites (azcomputerguru.com, analytics., community., radio.) are intermittently unreachable to any visitor whose nearest Cloudflare PoP chooses an origin-pull source in one of the affected prefixes.
## Workaround in place
We are setting up a Cloudflare Tunnel from inside our network outbound to Cloudflare (initiated from our side using working prefixes), so customer-visible outage is mitigated. Resolution of the underlying BGP issue is still required for any direct-proxied traffic and general Cox–Cloudflare connectivity health.
