AZTCOFW / TECHNICAL GUIDE
Diagnostic Tests
- Check connectivity from the firewall itself: Try to ping 8.8.8.8 (Diagnostics > Ping)
- If this does not work, ensure proper WAN settings, gateway, etc.
- Check DNS: Try to lookup pfsense.org (Diagnostics > DNS Lookup)
- If this does not work, fix/change the DNS servers on System > General
- Test NAT: Try to ping 8.8.8.8 (Diagnostics > Ping) using LAN as the Source AddressIf this fails but the other tests work, then the problem is likely Outbound NAT (See the WAN/LAN gateway checks above)
