Attempting to switch entire company to T-Mobile from ATT. Going smooth but our test team just hit major snag. T-Mobile appears to be blocking outbound GRE/1723/PPTP/VPN connections from the phones. We use VPNs to connect from phones to internal websites to perform work. When the phone is connected to the T-Mobile Data network the VPN does not connect. When the phone connected to ATT it does. When the phone is connected to wifi it works.
Are other people experiencing this same problem. in the old days one had to use a special vpn ap for mobile data. does tmobile have this?
thanks
