maikcat some stupid questions... did you also configured your router to forward udp port to your openvpn server? did you configured BOTH client server for udp? (and restart service to both ends) did you allowed udp traffic in server side firewall? (if is enabled) can you post server logs? Michael.
Mimiko Did you also changed the client configuration to reflect the new port? Like: proto udp and remote x.x.x.x 21195
Mimiko when I turned off iptables entirely, the client was able to successfully connect iptables -L -v
