NAT through router and ISA

[SCOTTF]

I am trying to set up NAT so that we can pull up a webpage
from our internal webserver from the internet. The
topology looks like this:

INTERNET
|
LINKSYS ROUTER
|
ISA SERVER/ internet gateway
|
WEBSERVER

What do I use to set up the NAT through the router..
Dynamic Routing, Static Routing, or forwarding?

You have to do it twice.

1st. Rig the Linksys router to "publish" you web server by treating your ISA
(external nic) as if it was the web server. Yes, ISA is not the webserver,
but you must treat it like it is from the Linksys Box's perspective.
Contact Linksys for details for configuring that if you need to.

2nd. Use the Web Publishing or Server Publishing features of ISA to publish
the internally located web server. Note the Web Publishing and Server
Publishing are *not* the same thing and behave differently. In most cases
with a simple system the Web Publishing is the feature of ISA you want to
use. Details for working with ISA can be found at www.isaserver.org and
also of course MS's website.
