I have a wireguard VPN set up for a friend where they can remotely connect to access frigate and I can remotely connect to fix things when needed. They are considering switching to tmobile buisness as their ISP since spectrum is screwing them on price, tmobile’s minimum is twice as fast as spectrum while still being a lower price, and AT&T can’t be convinced their small business isnt a residential duplex or an apartment.
Tmobile offers the Inseego FX4100 gateway which does have an IP passthru option, so my question becomes will that work to wireguard in with their current router/firewall solution hosting the other end of that and just passing packets through the Inseego, or is that just not possible without tailscale due to CGNAT?
ISP may offer a static IP, and/or help bypassing CGNAT if either are useful. I’ve done it for a 5G failover with VPN, with the gateway in passthru, and a firewall behind it. At a glance, it looks like the FX4100 supports all of this
it seems they do offer a static IP. I dont mind if the IP changes, we already have DDNS up and running fine. its more of a concern with CGNAT wrecking the VPN.
This was years ago - but I feel like the solution for CGNAT at the time required a static, and we also implemented DDNS for their TLD. It definitely wasn’t T-Mobile. It took some time to find someone at the mobile ISP who understood what we needed, and what options existed.
