Please help, proxy binds to wrong NIC.

[Gitendra]

I have one Windows 2008 Standard Server with two NICS:
NIC1: LAN 192.168.200.1
NIC2: WAN 10.200.200.2

DNS, DHCP, AD, Network Policy & Access Services are installed. All seems to
be working fine.
PPTP VPN works fine through NIC2.

Then I installed the Squid Caching Proxy and it seems to bind to NIC2. So on
the LAN clients I have to point the proxy to 10:200:200:2:3128 to get it to
work. So I tried another proxy called "FreeProxy", again it binds to NIC2.
Other than that it all seems to work.

Have I done something wrong in the server setup, shouldn't the LAN clients
point to 192.168.200.1:3128. Will I start to have problems?

Any help would be appreciated. Thanking you in advance.
