IP address assignment for VPN computers

Hi all...

I have a LAN in a site that connects to Internet by mean of an ISP. The
server in that LAN shares Internet access to all LAN computers using
ICS/ICF. Since I have ICS, the server was assigned the IP 192.168.0.1. Let's
name this site as S1.

I have other site that connects to Internet using other ISP. The server
shares Internet using RRAS/NAT configured as a VPN. This server is also
assigned IP 192.168.0.1. Let's name this site as S2.

When I establish the VPN connection from S1 (the client) to S2, all S1 LAN
computers lost connectivity to Internet (but not among them). I think it is
because of IP conflict among servers of S1 and S2..

What is the best way to manage this to work?

Thanks a lot in advance.

Jaime
