Using S-Tunnel in WAN

Hi,

I want to be able to use s-tunnel in a WAN environment.
The question is:
The PC I will use the S-tunnel client is in a 192.168.x.x network and it
does not use DHCP. The other host that will be running the s-tunnel server
is going to be in a remote WAN and it belongs to a 10.x.x.x network.

The WAN network has a firewall, but I will open a tunnel in the firewall for
the port stunnel will be using. 

How do I modify the connect parameter in the  client.conf? Do I put the IP
of the host in the 10.x.x.x network?

Thanks for answers,

Regards
