In my previous question I was asking about setting up vpnc connection. I've installed network-manager-vpnc so now I can configure all this stuff right from network manager gui.

I have got this pretty picture from related topic:

I have got this pretty picture from related topic:

So the question is how to figure out what Address, Netmask and Gateway should I use to pass ONLY this trafic through vpn.

As a basis I have got an ip and a port of the external service which I want to use through vpnc. So inernet and other traffic should go as always through ethernet or wifi.

  • External ip:
  • Port: 1433 (this is sql server actually)

Gateway ? Metric ? –  Muhammad Gelbana Mar 29 '14 at 22:20

I got "address", "netmask", and "gateway" in this way:

1) connect to VPN normally

2) run "ifconfig" command. output is somthing like this:

eth0      ....

lo        ....

ppp0      Link encap:Point-to-Point Protocol  
          inet addr:  P-t-P:  Mask:


  • set 'address' as the IP address you want to connect to it through VPN
  • set 'netmask' as 'mask' value in ppp0 output
  • set 'gateway' as 'p-t-p' value in ppp0 output
