I have a BR1 which is the front-end of my camper network. When connected to Verizon LTE via Cellular everything works, except the BR1 is showing an WAN IP address which is different than what my DDNS service is showing. DDNS shows 174.226.xxx.xxx, which is a valid Verizon address, while the BR1 shows 100.106.xxx.xxx, which does not appear to be a Verizon address (at least TraceRT routes it somewhere in New England).
Not that I really care about the actual address, but I’m trying to open a port and port forwarding uses the 100 address, not the 174 address.
Strangely enough, the BR1 correctly showed and forwarded via the 174 address for some minutes following to restart, then reverted to the 100 address.
