USG 110 - Port Forwarding 443

Bruant

Hello, We have added a lan2 for telephony. The external port must be opened for access to the autocom. I followed the usual procedure (https://support.zyxel.eu/hc/fr/articles/360001390934-Configuration-de-r%C3%A8gle-NAT-sur-un-transfert-USG-Port-Forwarding-)

The exterior port is 9090 to 443 interior but it doesn't work. Is there a specific opening autorisation for the port 443?
Thanks

Hi @Bruant  

After created port forwarding rules.

You have to also add  policy control rule for incoming traffic to LAN2.

Since 443 port is default WebGUI service, so you can change default service port to others. (i.g. 4443)

Configuration > System > WWW.

This setting can prevent you can’t manage device WebGUI from WAN side.

After changed HTTPS service port, you have to re-connect WebGUI by new service port.

(i.g. https://192.168.1.1:4443)

Hi.
It didn't work for the 9090 to 443 lan2, but changing port 443 from the usg to 4443, i was able to free port 443 for the autocom. it works so I'm not looking any further.
Thanks
