Hello,

 

I am trying to set up an openVPN Server to use your awesome tool to play Command and Conquer 3.

 

I have connection issues when I turned on the VPN, so I tried the status with the connection test tool.

Using server nntest.cnc-online.net:30000
Bound to local port 39199
Bound to local alternate port 39200
Resolving hostname 'nntest.cnc-online.net'...
Resolved server host to be '37.247.49.213'
Sending client INIT from port 39199 to nntest.cnc-online.net:30000
Received server INIT [853778]
Our public address is 164.68.121.122:39199
Sending client INIT2 [853778] from port 39200 to nntest.cnc-online.net:30000
Received server INIT2 [853778]
Our alternate public address is 164.68.121.122:39200
Sending cient START [853778] from port 39200 to nntest.cnc-online.net:30000

Server extra port is 40000

It appears your router and/or connection is not capable of NAT negotiation.
==> You will need to use port forwarding and possibly configure a static port.

Ip Tables

iptables -t nat -I POSTROUTING -o eth0 -s 10.8.0.0/24 -j MASQUERADE
iptables -I FORWARD -i tun0 -o eth0 -s 10.8.0.0/24 -m conntrack --ctstate NEW -j ACCEPT
iptables -I FORWARD -m conntrack --ctstate RELATED,ESTABLISHED -j ACCEPT

sysctl net.ipv4.ip_forward
net.ipv4.ip_forward = 1

 

I have no glue what I should configure on the openVPN Server to make it work.

 

Did someone install an own openVPN Server and could make it work? I would really appreciate a hint.

 

Thank you....
