OpenVPN Support Forum

Hey there. Im try to up my ovpn server under Windows 7 (64)
Under linux all working good, but under this one server wont open port and make routing.
Im use router DLink and make port forwarding (Radmin works good)
Im starting Openvpn as Service

Got in log: Attempting to established tcp connection...Connection failed and restart...

Any idea why?

Hello,

it is not ideal to use TCP with OpenVPN. (There are several uninteresting reasons for this.) OpenVPN uses UDP by default which is probably why you are unable to make a connection. Also be sure that UDP port 1194 is forwarded through your dlink router. In your client configuration file, remove "tcp" or replace it with "udp" on the "remote" configuration line.

Regards,
