SBS 2003 NAT Translation

Does SBS and ISA server handle NAT the way that we understand NAT, and if so, can you point me to resources that explain it properly.  I am unable to find something useful on the Internet thus far.

Isn't NAT NAT?  :-)  Yeah, I know there are tons of ways to handle though... it seems as though every router manufacturer thinks they've found a better way.

It's fairly straightforward in SBS... here's a BASIC overview:  http://arstechnica.com/guides/tweaks/windows2k3-1.ars/1

The best site for ISA info is http://www.isaserver.org and you'll find both tutorials and peer help there.  Here's their tutorial for ISA's SecureNAT Client setup:  http://www.isaserver.org/tutorials/The_SecureNAT_Client.html

Sorry... I grabbed the wrong link for the "BASIC" overview... that one isn't SBS.  Here's what I meant to post: http://support.microsoft.com/default.aspx?scid=kb;en-us;837453

Use ISA over RRAS for your NAT - since ISA is a firewall, all translations and routing are handled by ISA.

Not sure what you mean by "handle NAT", but, yes - ISA treats NAT the same way routers do only it's implemented slightly different than hardware.

This is how NAT works in XP - assume it is a similar implementation in ISA: http://www.microsoft.com/technet/prodtechnol/winxppro/deploy/nattrnsv.mspx
