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?
Our side supports ipv6 but I have no idea about T-Mobile’s setup.
TMO has had IPV6 implemented for mobile devices for years. There’s no way they only implemented IPV4 on a home/business service that uses the same network and the same towers.
Their sales rep emailed me back saying they use CGNAT and block WireGuard.
Yeah, i would not consider blocking wireguard to be even remotely (heh) acceptable in 2025. Tell your bro to go back to arguing with AT&T, maybe just with their resi service.
