it is better to setup NAT instead of ICS. quoted from

Do not install VPN on W2K with ICS running
Many users have reported that they were experienced some difficulties
after installing VPN on w2k/xp running ICS and ICS clients may receive
"Error: Page Can Not be Displayed" message. The reason is that
establishing a VPN connection on the ICS Host modifies the Routing Table
on the ICS Host. that will forces all clients that try to connect to the
Internet to use the VPN routing table instead of the ICS routing table
used to connect to the Internet service provider (ISP). You may modify the
route table to fix this problem, for example, route -p add <network> mask
<subnet mask> <router ip>. If you want to add a route for a single host
(firewall which is on another subnet), do this route -p add <ip> mask
255.255.255.255 <host ip>, for example, route -p add 192.168.0.100
255.255.255.255 160.213.320.1.
