ISa on a different link

[fuunstatic]

OK the main problems are in Internet Explorer with users getting "10060 - connection timeout" error message

Have tried all the suggestions from MS so, I am assuming it is because the link we are using is congested so I want ISA to route packets through our less congested link. How do I do this as I cannot change the default gateway for the following reason

The router is connected to the following 2 firewalls then to the internet
138.a.b.c firewall - heavily congested
138.a.d.e firewall - less congested

the router's default gateway is 138.a.b.c (router has 10.0.0.0 and 138.0.0.0 subnets binded to it on the inside)

Hi

ISA is on a 10.x.0.0 network, it's DF gateway = 10.x.0.y and cannot be changed to the 138.a.d.e gateway as it is on a different subnet

i want to make the ISA retrieve web requests via our other gateway which is ie 138.a.d.e. (firewall B) - "Less congested"

It has to be done at the ISA end because when it reaches the router, the router's gateway of last resort is always 138.a.b.c

any ideas as I want to avoid having to utilise a downstream isa server, thanks
