gmail SMTP fails with T-Mobile home network

I tried connecting over Ethernet directly to the Gateway, that doesn’t fix it.

I think I have a similar problem, in that gmail cannot send or recieve if I use an access point downstream from the T-Mobile modem.  If I connect to the modem wi-fi Gmail will work, but if I use the access point wi-fi (I used a separate SSID to know which I'm connected to) Gmail won't work.  Gmail does work fine from my PC, which is connected via Ethernet cable to the access point.

I'm connected to my work VPN and that doesn't fix it either.  What VPN are you using?  Or how did you set up the VPN - maybe mine isn't setup the same.

I cannot send an outgoing email from my email client to Gmail. The server times out and disconnects. It only happens if I use T-Mobile's ISP IP address. If I use VPN over T-Mobile's Network and it's associated IP address the outgoing SMTP email works fine to Gmail.
