Hey @PhilipDAth , That's the process I used. Here's specifically what I did: Existing setup has Port 8 on the switch plugged into the LAN port of the firewall. Firewall WAN direct to cable modem. Configured port 1/2 as "access" mode with unused VLAN (i.e., 20). At this point I had connectivity (pings) to the LAN IP of the firewall and to an external address (8.8.8.8). Moved cable from cable modem to port 1, cable from firewall WAN to port 2 At this point, the pings to the LAN address remain constant, but external pings cease. Upon looking at the firewall's status, it does not gain a public IP address from the ISP. You are correct that the WAN interface has no VLAN configuration and the connection to the ISP is a simple DHCP connection.
