Session Summary
Resumed remote-access work for Goldstein under Syncro ticket #32384 ("Remote - Issues with remote
access"). The stated goal firmed up over the session: the roaming laptop ASUS-2024 (Michelle,
user miche) must be able to RDP into two machines from anywhere — DALLAS (192.168.1.226,
Dallas office) and DalRes10 (10.1.10.170, Tucson office). Began by loading prior context
(#32490 Dallas RDP enablement, the June #32384 attempt) and confirming machine identities.
Mapped the entire Goldstein network from the UniFi Site Manager cloud API + connector proxy: both
sites run a UCG-Ultra (UDRULT, Network 10.4.57) that we own in our ui.com account. Established that
the Tucson↔Dallas link is a UniFi Site Magic auto-mesh (WireGuard-based, wgsts1000) that is
auto-managed/locked (attr_no_edit/attr_no_delete) and bridges only the two corporate LANs
(10.1.10.0/24 ↔ 192.168.1.0/24), verified working both directions. Discovered the June "WireGuard"
was actually Teleport (enabled on both gateways) plus leftover machine-level WireGuard tunnels.
Diagnosed why ASUS couldn't reach the offices: it was on the office's separate Cox network
(SSID Gold-Scop, 192.168.0.0/24), which is not the UniFi LAN and not on Site Magic. Mike
directed switching remote access to OpenVPN. Mike disabled Teleport (I confirmed/executed the
Tucson toggle), then set up native UniFi OpenVPN remote-user servers on both UCGs (TCP 1194,
RADIUS auth, pool 192.168.2.0/24 on both) and created RADIUS users Michelle + Sheldon on both
gateways. I vaulted the RADIUS secret + both client .ovpn profiles + user creds, then deployed a
split-tunnel OpenVPN client to ASUS-2024 (OpenVPN 2.6.14) and proved the tunnel up. Testing showed
the Tucson-anchored connection reached Tucson but not Dallas — the OpenVPN pool doesn't traverse
Site Magic. After pulling the live config (as Mike requested), confirmed this is a hard Site Magic
limitation, so the offsite design landed on two profiles (Dallas profile → DALLAS, Tucson
profile → DalRes10), and the office design on Site Magic with the VPN off (on the UniFi WiFi).
DALLAS offsite RDP was confirmed working (Michelle imported the Dallas profile). DalRes10 had been knocked fully offline earlier in the session when someone activated its machine-level WireGuard tunnel (full-tunnel captured its own routing; no remote path — required onsite console deactivation, which happened ~4pm). Closed out by updating the Goldstein wiki with the complete topology, and adding Defender exclusions for the OpenVPN config folders + confirming Defender re-enabled on ASUS-2024. Howard is removing the DalRes10 WireGuard himself.
Key Decisions
- Switched remote access from Teleport/WireGuard to OpenVPN (Mike's call). Teleport's June failures ("steps on routes at home" = subnet overlap; "login credentials incorrect" = Ubiquiti account / RADIUS) and the machine-level WireGuard tunnels (which took DalRes10 offline) made them a poor fit for a roaming law-firm laptop.
- Offsite = two OpenVPN profiles, not one-connection-both. Pulling the live gateway config proved UniFi Site Magic is auto-managed/locked and carries only corporate LANs — it will NOT route the OpenVPN client pool (192.168.2.0/24) across the mesh, and there is no way to add it. So a single offsite VPN connection cannot reach both sites. Two profiles (connect the one for the target machine) is the working design; abandoned the earlier "de-conflict pool + advertise across mesh" idea because Site Magic cannot be extended.
- Office = Site Magic with VPN off. A device on the Tucson UniFi LAN (10.1.10.x) already
reaches DalRes10 (local) + DALLAS (mesh). The catch is the laptop must be on the UniFi "Goldstein"
WiFi, not the separate Cox
Gold-Scopnetwork. - Split-tunnel OpenVPN client (drop
redirect-gateway def1,route-nopull+ explicitroutelines) so a client can never full-tunnel itself offline the way the WireGuard tunnel did. - Used the vault skill for all secrets and referenced vault paths in the log rather than committing plaintext (pre-commit guard + vault-skill rule).
- Did gateway config in the UI (Howard/Mike), not via raw connector writes — after a mid-session correction that hand-rolling the UniFi API instead of the skill is wrong; the skill has no VPN-server command, so the server build was done in the UI.
Problems Encountered
- DalRes10 taken fully offline by its own WireGuard tunnel. Activating the machine-level
WireGuardServer1-Client1-style tunnel installed routes that captured its network path (RMM + ScreenConnect both went dark). WireGuard does not time out; a reboot would re-break it (auto-start service). No remote recovery possible — required onsite console deactivation (~4pm). Resolved by onsite visit; Howard removing WireGuard. - Cross-site VPN routing dead-end. ASUS on the Tucson OpenVPN pool (192.168.2.2) reached the
Tucson gateway but not DALLAS. Root cause: Site Magic advertises only the LANs and is locked
(
attr_no_edit), so the pool can't be carried. Both OpenVPN servers also use the same pool (192.168.2.0/24). Pivoted to the two-profile design. - Corrected hand-rolling the UniFi API. Was reading (and made one write — Teleport disable) via
raw
curlto the connector instead of theunifi-wifiskill. Logged as a correction; skill'sgw-sitemanager.shis the read path, but itsnet … rawtruncates at 5 KB, so full networkconf legitimately needs a direct connector read. - Defender ate the OpenVPN
.ovpn(embedded private key). Added Defender exclusions for the OpenVPN config folders; Defender had already auto-re-enabled (tamper protection), confirmed on. - DalRes10 cleanup command timed out (server-side reaper at 120s; the
wireguard /uninstalltunnelservice/ manager-stop hung). Backed off to a read-only diagnostic; Howard then opted to remove WireGuard himself. - RADIUS username mismatch — Howard typed "michell"; the actual RADIUS account is
Michelle. Corrected the vaulted username to match the gateway. - Local
curl/jq friction — a/tmppath tripped the block-tmp-path hook; a jq filter with a rawC:\Program Filespath failed (invalid JSON escapes) — fixed by passing PowerShell viajq --arg, not inline.
Configuration Changes
- ASUS-2024 — installed OpenVPN Community 2.6.14 (service OpenVPNService/Interactive); deployed
then removed a split-tunnel
goldstein.ovpn(Howard re-imports via GUI); added Defender ExclusionPath forC:\Users\miche\OpenVPN,C:\Program Files\OpenVPN\config,C:\Program Files\OpenVPN\config-auto; createdDallas Computer.rdp(→192.168.1.226) on Michelle's OneDrive Desktop + Public Desktop. - CGU-Goldstein Tucson (UCG) — Teleport disabled (setting
teleportenabled=false) via connector write; OpenVPN remote-user server (Mike, UI). Site Magic + Dallas mesh unchanged. - CGU-Goldstein Dallas (UCG) — OpenVPN remote-user server (Mike, UI); RADIUS users Michelle + Sheldon (Mike, UI).
- DalRes10 — WireGuard tunnel deactivated at console (onsite); Howard removing WireGuard.
- Vault — created
clients/goldstein/openvpn-remote-access.sops.yaml. - Wiki — rewrote
wiki/clients/goldstein.mdwith full network + remote-access topology. - Repo — logged one correction to
errorlog.md(unifi-wifi hand-rolled API).

Pending / Incomplete Tasks
- DalRes10 WireGuard removal — Howard doing it manually. When done, set TermService → Automatic so RDP survives a reboot.
- Tucson OpenVPN profile on ASUS-2024 — import the
98.225.73.165.ovpn(split-tunnel) alongside the Dallas one so Michelle can RDP DalRes10 offsite (connect the Tucson profile for DalRes10, the Dallas profile for DALLAS). - Office WiFi — ensure ASUS joins the UniFi "Goldstein" WiFi (10.1.10.x) at the office, not
Gold-Scop(Cox), for the VPN-off / Site Magic path. (Confirm exact SSID mapping.) - Billing — #32384 was already Resolved/invoiced in June; new OpenVPN work not yet billed — confirm with Mike whether to bill.
- Remove machine-level WireGuard on ASUS-2024 (
WireGuardServer1-Client1, inactive) for hygiene.
