Windows 8.1, using OpenVPN GUI.
Here's the log:
http://pastebin.com/26sWCHV2. %HOMEIP% is my IP, blanked out for security reasons.
My setup is: ATT Uverse 3801HGV modem/router, with an ASUS RT-AC68U piggybacking as the main router for the house.
Port forwarding is set up so that port 1194 forwards, using UDP, from 3801HGV to AC68U. Port forwarding is not set up on AC68U, as I believe no forwarding is needed past this point (AC68U has native vpn support). Using OpenVPN 2.3.4.
The 3801HGV is a DHCP server for all the home devices, but all devices pretty much have a set local IP that doesn't change. The AC68U is 192.168.2.1, for example.
Here's the config (.ovpn) file, minus private keys and home IP:

My home IP is static, but maybe something gets lost being passed through from the 3801 to the 68U.
So am I missing something? Does AT&T not allow for VPN connections or something?
Any ideas?
