Multi-wan suggestion

[hongyee]

I am thinking of having another ISP  to my setup.  I am thinking of doing the following

WAN1 : use it for connecting to another site via VPN, however certain host would be using this to access the internet
WAN2: use it for general internet usage but not connecting to another site VIA VPN.

was wondering what might be the best approach. I was thinking of using firewall rules to restrict access to vpn via wan1 and add exception for 1 or 2 host. was just wondering if this would be the best idea.
