I have openvpn server running on debian lenny. There is only one client - and it is running Windows
7 64-bit. This has worked for few months without any problems. And now, let's say for the last
7 days, it doesn't work at all. I connect successfully from client to the server, but I can't access anything through VPN. I have set it up so that all internet traffic is routed through VPN, and now when I connect with the client, the client can't do anything on the net (open any webpage, ping google, anything ...).
Can you help me to figure out what's wrong ? I don't know where to start. I've also tried to connect to another openvpn server (I've installed and configured openvpn on another server, and when I try to connect to it result is the same). So I think there's something wrong with client ...
Here is my connection log:
