I was wondering, i have a server running 2003 server with all of the lastest updates, and isa server 2004 running on the server, now i have it setup the way i want but i want to add a backup route for the traffic in case the firewall service or the proxy service stops working or responding. I am wondering if i need another proxy server or can i just a regular server. Well i implemented the isa server, and well if it goes down i don't want the network to lose internet access, so traffic would be passed along to another connection or server, how ever it would work, but some ideas would be great so i have a better understanding of how this feature works.
