I may just be going about this the wrong way, so I need some advice. I currently have a Cisco 1700 series router with Firewall IOS controlling internet access/NAT/Firewalling. I'm confortable with confiuring the Cisco, but I want to implement an ISA server. The 1700 plugs directly into a 3600 series router that server Point-to-point links between the rest of my sites.
What I want to do is drop the ISA box inbetween the 1700 and 3600, ensuring that all outbound/inbound traffic goes through ISA, however I want the Cisco machine to continue to do NAT... Is this possible? Will I instead have to assign the external IP scope to the ISA machines second interface and route the packets to it and let it do the NAT?
Any advice would be appreciated.
