If the IP address isn't owned by the server on which ISA resides, you can't
use it.

Here's my situation:
I have 3 websites on an IIS behind the ISA server. I want to create NAT
entries so the external addresses for the websites are routed to the
internal addresses of the websites.

Example:
Website1 - internal address 192.168.0.1, external address 64.0.0.1
Website2 - internal address 192.168.0.2, external address 64.0.0.2
Website1 - internal address 192.168.0.3, external address 64.0.0.3
ISA server address 64.0.0.4

I want to create a NAT rule that says - route external address 64.0.0.1
to 192.168.0.1, and so on.

When I create a server publishing rule, it only allows me to choose the
ISA external IP address, 64.0.0.4. I cannot enter any other addresses!

Thanks!

Hi N,

That is what Server Publishing Rules do. They perform reverse NAT and
expose the inbound packets to the application filters.

HTH,

I'm trying to create a NAT translation table to route a public IP to a
private IP. How is that done? Is that done with IP Packet Filters?
I have the ISA Standard server.

I looked at many tech pages, but it I only see references to
'SecureNAT'.
What is that and is it the same as NAT?

Thanks a million!
