GlobalProtect VPN not working with T-Mobile
I have seen several posts about VPNs not working with T-Mobile Home Internet. What is T-Mobile's plan to address this? I contacted my corporate IT department and they said it's not their VPN. All wor...
No luck so far. I even had T-Mobile roll back the version of my gateway's firmware, because I had heard that fixed the problem for some people. The service rep said he couldn't do it, but when I said I needed to cancel my service then, suddenly it became possible. It did get a little better, some web pages eventually load, but it's still not usable.
I have one last thing to try. There are some people who say lowering the MTU setting for globalprotect to 1350 or less might solve the issue. I doubt it will work, but I'm going to try it. I don't have access to do it myself, but I'll try to get the IT guys to do it when I'm in the office on Tuesday. If you have admin access on your machine you can try it yourself:
netsh int ipv4 set subinterface “Ethernet 2” mtu=1350
Replace “Ethernet 2” (keep the quotes) with whatever name your computer uses for the globalprotect virtual interface in ipconfig.
