Hi guys,

Thanks for a great site.

I am looking for assistance and was hoping someone out there could help.

In my country connectivity costs are exorbitant. In an attempt to reduce costs and try to get as much bandwidth as possible the following option is availble. I know it is not the ideal configuration but because of the low costs I need to determine if the following is possible:

We currently have a single line to the internet protected by an ISA 2004 firewall.

The proposed solution would involve 6 broadband connections to the I.S.P. ending in 6 Cisco 837 ADSL routers. 5 X Public IP addresses on each router.

I would like to route outbound traffic based on certain criteria i.e.

-1-> Management would have a single link dedicated to them.

-2-> Mail would travel out through the second link.

-3-> Hosted servers would utilize the third link.

-4-> Branch connectivity (VPN) would utilize the fourth link.

-5&6-> Finally, general browsing could utilize the fifth and sixth links combined.

The question is can I do this with 1 firewall?

I've looked at source routing but apparently it can't be done with Microsoft products (Please correct me if I'm wrong) and would require me to use either a linux based firewall, or multiple firewalls with a router on the internal network to provide me with the source based routing.

??

Thanking you in advance for your assistance in this regard.
