Scenario
Remote workers lose VPN access after a modem or router swap at home or at the office.
Recommended Resolution Path
- Verify port forwarding, passthrough, and public IP changes after the equipment replacement.
- Test whether the office firewall still presents the expected certificate and listener.
- Check MTU and fragmentation only after core routing is proven.
- Document the known-good WAN edge settings to accelerate future recoveries.
Technician Notes
Confirm the business impact, document the root cause, and capture any preventative follow-up in the PSA or client knowledge base.
