My current ISP goes down every once in a while so I set up another T1 line for redundancy. I'd like to plug in another NIC card and have ISA take care of the failover. ISA would also have to know how to receive incoming traffic (mail, ftp, http, etc.) I am working with the second ISP to see if they can publish my current class C addresses so I don't have to run BGP on my routers. Does anyone else have a similar setup? If so, I'm curious to know how it works for you. Karl Schneider
