<div>
are you assuming the ISA box is 192.168.100.1 in the config above?

I was assuming that the ISA is the default gateway for the 192.168.100.x network, and that its network IP is 192.168.100.1... substitute appropriately to fit your layout.<br />
<br />
Thanks!<br />

I have two networks built at one of my remote offices. 10.80.33.0/24 is on my MPLS link to corporate. 192.168.100.0/24 goes out a local T1 for internet access. I want to route all web traffic (port 80) from the 10.80.33.0 network out over the T1 on the 192.168.100.0/24 network. there is an ISA proxy on the 192 network between the internet router and the 192 network.

Policy Based Routing

A router is a networking device that forwards data packets between computer networks. Routers perform the "traffic directing" functions on the Internet. The most familiar type of routers are home and small office cable or DSL routers that simply pass data, such as web pages, email, IM, and videos between computers and the Internet. More sophisticated routers, such as enterprise routers, connect large business or ISP networks up to the powerful core routers that forward data at high speed along the optical fiber lines of the Internet backbone. Though routers are typically dedicated hardware devices, use of software-based routers has grown increasingly common.

Routers

Networking hardware includes the physical devices facilitating the use of a computer network. Typically, networking hardware includes gateways, routers, network bridges, modems, wireless access points, networking cables, line drivers, switches, hubs, and repeaters. But it also includes hybrid network devices such as multilayer switches, protocol converters, bridge routers, proxy servers, firewalls, network address translators, multiplexers, network interface controllers, wireless network interface controllers, ISDN terminal adapters and other related hardware.
