I think what you want to do is set up a VPN.

Are you running publicly routable IPs?

by georgeou In reply to reg:routing

You can't route private IPs through the public Internet unless you're at least using a GRE tunnel or an IPSEC tunnel. Please explain in detail.

FYI, this belongs under "Questions" and not under "Discussions".

Hi George,
We have a dedicated line between our US office and our Indian office.And the MPLS circuit is already there and it acts as a tunnel.
In simple my computers in chennai using the private IP shud browse internet using the router in US which gets the public IP.I just want to do a NATTING if I am not wrong....
provide me with the NAting table

Can you provide a diagram and a detailed explaination?

by georgeou In reply to reg: routing

I'm not exactly sure what you're trying to do. Your choices for routing with MPLS is either static or BGP since you don't have an actual point to point layer 2 connection between the sites.
