Anyone passed FW full cone tests using Ubiquiti EdgeRouter ?

[Robertos]

Can't see any relevant config to set to pass the FW Full Cone tests cleanly ...

Passes on the UniFi side no problem. Haven't tried withe a EdgeRouter.

Was there any doc you can refer me too or any special trick ?

Nope. Just standard port forwarding and disabling SIP ALG. Did you disable SIP ALG?

hi buddy yes this was already disabled. The SIP ALG checker always passed FYI. Only full cones fail

Hello @Robertos

You could run a firewall capture along side the firewall checker test to confirm where this is failing using the following guide. https://www.3cx.com/docs/firewall-checker/
Also perhaps the following links could provide some assistance:
