All this talk about TCP/IP routing has reminded me that I have a situation I might need an answer for before it is asked... We "might" have the ability to link up directly with the local university via a fiber connection. In theory, this sounded great, because we could then stream video at gigabit speeds and such. However, the more I think about it, I'm not sure how to set it up... We have a private subnet here (10.x.x.x), and almost all of the computers we'd be conversing with have public IPs. I was thinking of setting that network up as a DMZ (private IP range) on the ISA2004 firewall, but I cannot figure out a good way to route traffic from our private network, through another private network, to a computer with a public IP(and back again). Anyone have any good ideas on this?
