hello fellow ubuntu geeks ;)
I've set up an ubuntu server 10.04 lts with openvpn up and running. on installation I created server certificate and key first, then I created two client certificates. all this was done according to the tutorial at https://help.ubuntu.com/community/OpenVPN
after that I installed openvpn on a win7 machine, changed the .conf file, added the certificate and key and everything was cool! worked like a charm - I couldn't believe it!
but then, problems began to rise high! I tried to do the same on another win7 machine with another certificate/key but the same .conf file (location of certificate/key was adopted, of course). the first run was successful but afterwards, all I get is a TLS error!! so, I tried to change the firewall policy, but this wasn't the solution either.
in the meantime, I also tried my luck with an OSX Lion machine and Tunnelblick (for OpenVPN connections), but again, the same TLS error appears every time I try to conncet. on top of all this, the error is also raised on a Kubuntu 12.04 machine!!
I read across the openvpn.net page, tried every possible solution given at http://openvpn.net/index.php/open-source/faq/79-client/253-tls-error-tls-key-negotiation-failed-to-occur-within-60-seconds-check-your-network-connectivity.html but still I'm facing the same error over and over again!
It seems that it is not a problem at the network connection at the server because I'm able to access the server from the one working win7 computer without any problems!!
what else could cause this error? am I failing at something obvious?
thanks in advance for your help, herom
