How to use bridge mode on Telus NH20A modem
I switched to Telus a week ago and tonight I attempted for a couple hours to set up my own gateway/router using the Telus modem in bridge mode. Is there an official guide on how to set up bridge m...
While I have a UDM-PRO, I am using Pfsense to route my WAN connection and as my firewall. Unifi software makes this pretty straightforward to do and it seems you have your unifi settings correct. Use VLAN 40, not 35.
You didn't mention your Telus Modem settings. Did you set bridge mode there?
Suggest using Partial bridge mode and assigning bridge port to be the 10G port. That will leave the remaining ports as normal DHCP assigned ports direct using the Telus modem as the router. If you set full bridge mode, you won't be able to access the modem config anymore. If you have already set FULL bridge mode, reset your modem - your PPPOE login settings etc will all stay. Make triple sure you have noted these down correctly.
You may also be getting snagged with conflicting LAN IP DHCP pools. If your Unifi is using 192.168.1.x for the LAN Subnet and the Telus modem is using the same subnet for it's DHCP LAN pool, it won't work. Change your Telus modem to use 192.168.2.x on the LAN side.
feel free to PM me if you have further issues.
Thanks so much for the reply. Yes, I tested bridge mode with “full” first, then reset and tested 10G only once I realized I couldn’t access the modem interface in full/all ports bridge.
Good point on the conflicting DHCP pools, that could be it. Could be a rookie mistake 🤦♂️ I’ll try that out.
I appreciate the support and offer for PM.
Cheers 🍻
Once you have adjusted the LAN DHCP pools, that will allow your router to pull a DHCP address from a non-bridged modem port and run in double-NAT mode. This is a good middle ground while you figure out how to get full bridge mode working and make unifi pull the external WAN IP.
To use double-NAT mode, change your unifi WAN settings back to DHCP or default. You will also need to move your cable to one of the other non-bridged modem ports.It is perfectly fine to leave it this way if you don’t have any advanced need to forward inbound traffic or ports to devices on your internal LAN. Otherwise you will need to configure two firewalls (Telus’ and Unifi) to make the forwards work properly.
