NH20T in Bridge Mode/Speeds/General Home Networking/XGS-PON

Residential connections are permitted 2 dynamic IP addresses. For troubleshooting purposes it is easier to just bridge the 10G port, especially since Telus tech support won't troubleshoot non-Telus hardware. If 10G Bridge is enabled, the 4 LAN ports on the NH20T would share one WAN IP, and your router connected to the 10G port would have the other.

If you used Full Bridge, all ports would try to pull separate WAN IPs and only the first two devices would work and swapping out a device may take time for the DHCP lease to expire before the next device will work. Worst case you would have to call tech support each time. Full bridge means every port is directly exposed to the internet as well so you'd need to ensure that you have a firewall in place. Your router connected to the 10G port can use whatever IP range you want as it'll be separate from the 4 LAN ports. A different IP range would make differentiating networks a bit easier when troubleshooting.

If you have the older non-AndroidTV based Optik TV boxes, only use 10G Bridge and ensure the Optik boxes are connected to the four LAN ports. The main reason is that most third party routers don't support multicast data properly so the Optik boxes won't work when connected to them. If you have wireless Optik TV boxes, you'd need the Wifi 6 AP from Telus connected to one of the LAN ports also. If you have the new TelusTV+ AndroidTV set top boxes then multicast won't matter and they should just work when on a non-Telus router, but data use when watching TV may count when connected to a thid party router rather than an unbridged port / the Wifi 6 AP on the NH20T.
