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.

Active Work

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).
