Forward port 53 to 1194

[rainbow6]

What your router public IP? This is the server-ip-address. It gets complicated when its on dynamic IP.
Remove all rules referencing tcp ports to 1194 if 1194 is not running on tcp.
You should only have UDP 53 and 389 redirects to 1194.
You need to open port 1194, 53 and 389.

That's all you need to do to allow connections and to make sure that there is no process using port 53, ssh to ddwrt and run netstat -a and see if the list contains any processes listening on port 53.

Get additional support in DDWRT forum as I think here is not the right forum as this is not openvpn issues.
