I have 5 static public IP addresses but only one ISP. I have 2 Linksys routers - one servicing one external domain, and one another. The problem I have is that I can't seem to get my routing straight. The two routers are at: 10.2.1.1 and 10.2.1.2 I have everything set to default gateway 10.2.1.1 Doing this, communication through 10.2.1.2 from the internet doesn't work. For example, smtp mail hits my internal Exchange server and I assume it tries to get back out through 10.2.1.1. If I set my exchange server to use 10.2.1.2 it works, but then breaks on th 10.2.1.1 router. Is there a way to tell each router about each other? Both are WRT54GS routers. Lets make it even more complex. There are times when I set up a vmware environment that runs its own internal Active Directory and Exchange environments, usually with an ISA server facing my internal network, which is a 10.2.1.X 255.255.255.0 network. Inside the vmware environment I will have a 10.3 and a 10.4 with virtual routers between them. I normally have to add static routes on my linksys hubs to get routing correct. The big question.. would removing the default gateway from all my internal systems (as much of a huge pain that would be) be the way to go? And if I did, how to my systems know how to get out to the internet etc? Perhaps I'm using the wrong routers? I tried removing the default gateway on just my Exchange server, but that did not work.
