[H-GEN] Connecting to 2 ISPs one entirely just for theFreeZone, How?

[Crowy]

Ok, seems I need to clarify a few things based on the questions from the
replies, also reword a couple of things, I'll start by rewriting my original
question minus the diagram :)

Background:
 Current network setup is a IPcop box with a single ADSL connection through
Wild Internet. We have a debian Squid Server on the LAN.

Main reason for adding second ISP:
 Improve Pings in games, and give fast downloads of updates for said games.
Hence the new ISP connection is a Bigpond Cable connection, but I only wish
to allow free traffic on this connection as additional traffic is charged at
15c/MB

Now does the squid proxy really need to know anything about the changed
routes? Or does it just need to request everything from the router as per
previous?

Ok well I will have to do either DNS lookups myself or script it to check
http://www.bigpond.com/unmetered/ to check what is and isn't freezone
(maintain a list in short) and then make appropriate changes to whatever
config files need changing. So I will need to be making the either a URL or
IP list.

Ok if IF1 goes down then PCs can access freezone through IF2, but if IF2
goes down then only freezone will be available, all other traffic should be
dropped/rejected/etc(whatever is neater).

Thankyou all for your time and responses :)
