Archer VR2600 in bridge (modem only) mode
I have an Archer VR2600 which I've been using a few years. I've recently purchased some Unifi kit, and want to now use the archer purely as a vdsl modem, connecting out to the WAN port of my unifi gateway. However, I've been unable to get an internet connection working in this way. In normal modem/router mode, the internet is fine (BT Internet VDSL)
To set it up as a modem only, I deleted the old internet PPPoE settings and replaced it with "Bridge Mode". I kept the VLAN ID as 101, the same as it was for the standard internet connection setup.
I've changed the LAN gateway settings to 192.168.2.1 so it doesn't conflict with the USG gateway, which uses 192.168.1.1 (as the archer did before)
I've also tried turning off DHCP and wireless settings but it didn't seem to help
To test it outside of the Unifi environment I tried connecting an ethernet cable directly from the LAN1 port to my PC, and setting up a new broadband PPPoE connection that way - this also didn't work.
Can anyone please advise me what I'm doing wrong, or how to diagnose this further?
