Hello,
I'm trying to figure out how to set the same VLAN on both the P1 (WAN) and P2 (LAN1) ports (if possible).
I have a modem/router -> firewall -> LAN with Desktop PC and Cisco IP phone.
The Cisco phone need to speak to the router using the VLAN50.
On the router I have a static NAT to the WAN IP of the USG20W firewall.
In general I can make this work using a switch, connecting the router and the firewall to it and configuring the right ports with the correct tagging/untagging.
But I want really understand if this is a configuration I can obatin also without using the switch configuring the firewall ports.
Thank you.
