I have calyx hotspot/ tmobile home internet. Ive been having issues with my work Palo Alto Global Protect VPN and tailscale. Neither of them seem to stay connected. They will work for a bit after I reboot my modem. I am using the glinet spitz 5g modem. Any tips for band, MTU, or APN for better experience?
T-Mobile doesn’t support IPv4
This is categorically false. You can even request a static (IPv4) IP if you have their business 5g router.
Is that a recent change? They did support it (with cgnat) when I had TMobile home internet about a year ago.
