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?
It probably has to do with being native ipv6 and needing to ride a 6to4 nat to reach the broader internet.
Start at 1400 and walk the MTU down by ~50 until you find stability, then id creep it back up by 10 to find the ‘perfect’ size, but that part isn’t really needed if you’re impatient. :)
E. I found 1290 was needed for reliable VPN over an ATT nighthawk hotspot.
