Hi Chad, I have those blocks of IP Address too! However, I've only had to use 2 of them. 1 for all the sites that I'm hosting and working on and I use 1 for mail. I've not had a need for those since I use host headers for the web sites. I think it also makes working with ISA easier. I'm sure you could possibly use all those address but in my opinion is not necessary. Look over the articles over at http://www.isaserver.org and search for host headers.

We have requested additional IP's as our publishing needs have grown. Our ISP has allotted us an additional range of IP's with a different network ID, and is telling me that I need to add them to our NAT table as they have configured the router to forward them to one of our orignal IP's. By doing this I get to use all 32 of the IP's they are giving me, but I can not assign them to the external interface. How would I go about configuring this? The other option would require my ISP to configure an additional default gateway, and then I can assign them to the external interface. Can someone give me some advice on how to handle this? Would I need to add an additional interface to handle the range of addresses with the new gateway?
