# Darrell Delphen

## Profile
- **Contract type:** Break-fix (no prepaid block)
- **Key contacts:** Darrell Delphen
- **Billing rate:** $150/hr remote (most recent labor)
- **Location:** Yantis, TX
- **Syncro customer ID:** 35996725
- **Managed devices:** GuruRMM agent on DDDOffice072023 (0 assets recorded in Syncro)

## 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

*No open tickets in Syncro as of 2026-06-18.*

## 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).
