Hello there,
I have a proxmox server, to all effects a debian wheezy, that I want to remotely manage without having to open multiple ports on the router. I've already installed it as per wiki intructions, configured and generated server and client keys.
Ports are opened/NAT generated for udp 1194 on the router.
The testing client is my own Windows 7 computer. I have copied there the user certificate and ca, and generated a configuration.
The problem is that I can't connect to the server. When I try, I get the following log on the client GUI:
Thu Apr 16 10:39:19 2015 Socket Buffers: R=[8192->8192] S=[8192->8192]

.....
The client fw is down. The router registers the incomming connection and redirection from the client to the server 1194 port.
The servers fw is also down, but when I use a common port scanner tool on it from inside it's network, it shows several management ports open but not the 1194, or nothing listening to it.
Executing service openvpn status on the server shows it running.
Please, can someone give me a pull for getting this working. Surely must be something I missed while configuring it.
Thanks for your help in advance.
