Hi, I have not yet installed ISA server and require clarification of a little point before I do.
Several of are internal workstations will require access to an external server. The external server will only allow access from specific IP addresses and (unfortunately) the server admin will not allow us to register the ISA servers external IP address as an acceptable client.
Is there any way a specific internal address can be "NATed" to a specific external address? ... but that would mean an external network card with two IP addresses ... which can't happen.
I have thought about having several external cards in the server but this seams a bit drastic. However drastic solutions are acceptable.
You are not wasting my time! However, if it takes me awhile to get back, its because I can only get to about 15-20 responses a day.
The problem with the solution in the link you provided is that you cannot run both the Win2k RRAS NAT and ISA Server. The two will conflict and you'll end up with more problems that you want (I tried it for awhile and its not fun).
Thanks I will set up a dmz as you suggested. I thought there were issues running ISA and RRAS, thanks for confirming this. I now consider the matter closed and look forward to a future ISA where I can do what I wanted.
I'm a little bit confused by your reply, do you think I was criticing your response time?? Certainly not! I am very impressed with the qulaity and response time of all replies on this message board. In fact its a joy to see such as well run site.
