Here is my senario...
Our head office is located in Uk on network.
gateway and router ip is
Our branch office located in India on network.
gateway is
These two offices are connected using hardware VPN so we can ping and connect both end.
Now we need to connect to a particular ip in Uk from India side through the Uk office. ie traffic to that particilar ip should pass through the router.

Is there any way to do that on linux using route or some iptables rule?

Thanks in adv
