## Infrastructure
|
|
|
|
### Servers & Services
|
|
| Host | IP | Role | OS | Notes |
|
|
|---|---|---|---|---|
|
|
| DDDOffice072023 | LAN behind 192.168.1.1 | Workstation | Windows | GuruRMM agent `000ed57d-fd05-4001-871c-244f43155c16` (v0.6.66); ISP egress 167.89.210.225 |
|
|
|
|
### Email & Identity
|
|
- **Mail security:** Intermedia Email Protection (rewrites links to `url.emailprotection.link`). Mailbox accessed via Outlook. (verify tenant/host details)
|
|
|
|
### Network
|
|
- **ISP / WAN:** ISP-provided/managed **Extreme EXOS** gateway (LAN gateway 192.168.1.1, egress 167.89.210.225). Client has no login to this device — changes require ISP escalation.
|
|
- **Firewall:** the EXOS gateway runs ISP-side web/URL filtering (the "NetIQ" feature) capable of SNI-based TLS inspection.
|
|
- **VPN:** (verify — none known)
|
|
|
|
## Access
|
|
- Remote management: GuruRMM (agent on DDDOffice072023)
|
|
- Vault path: (verify — no client credentials vaulted)
|
|
|
|
## Patterns & Known Issues
|
|
|
|
- **ISP gateway SNI filtering breaks Intermedia/Outlook email links.** The ISP-managed Extreme EXOS gateway's "NetIQ" URL-filtering feature has SNI-intercepted and reset TLS to `url.emailprotection.link` (Intermedia's link-rewriter), producing `ERR_CONNECTION_ABORTED` / SChannel `0x80090326` (SEC_E_ILLEGAL_MESSAGE) on Outlook links while Gmail links (Google redirector) worked. The client cannot change this device — resolution requires an ISP ticket. If it recurs, suspect the "NetIQ" feature being re-enabled and confirm with an SNI-varied handshake test against `199.193.205.140`.

## History Highlights
|
|
|
|
- **2026-06-18** — Diagnosed Outlook email links failing (`ERR_CONNECTION_ABORTED`). Root cause: ISP EXOS gateway "NetIQ" feature SNI-blocking Intermedia's `url.emailprotection.link` rewriter. Deployed Cloudflare WARP as interim bypass; ISP disabled the feature for the permanent fix; verified native path and removed WARP. Billed 1.0h remote ($150, Syncro #32437 / invoice #67853).
