Post by ibaxx »

Ah ok... you mean, insetad of the domain...
I have dyndns with this domain... thats the fact that i have chosen openvpn and not other types with android kernel based solutions.

the strange thing is, we have more than one accesspoints on our workplace, with other ssids.
i found one ssid where are no problems with the vpn connection suddendly today it breaks and i am not able to connect again.

openvpn app works...

here is the log from this network:

No, I meant the protocol used by the VPN.
The OpenVPN server/client can be configured to use UDP or TCP protocol.
At the moment your VPN is configured to use the UDP protocol.
