Ответ в теме: VPN туннели для подключения к сервису

I want to run voip over vpn using softether software.

I noticed (as you explained) that the default ip (192.168.30.1) is no more than a dhcp/nat service, so no other internal services such as ssh or for the case brekeke sip server are running on that ip.

I recently solved the this problem of connectivity by running a softether vpn client on the same machine where is running softether vpn server and brekeke sip server.

Once the client is running a virtual interface is created and I can configure the brekeke sip server refering to this virtual interface.
