Status: offline 		We currently have checkpoint firewall installed on our network. I dont want to replace this with ISA server right away, but I want to install ISA server do some testing and as soon as I know everything about ISA I will replace it.

How should I configure My ISA server so it works with check point togather as backend firewall. can someone please guide me to right direction?

Currnetly there is some NAT done on checkpoint firewall, I want same thing on ISA how I do that so I can test that.

thanks

Here's what I am trying to do?

My pc is configured with firewall client?
I am using IP address which is routable IP address?
what I need to do so that I can access my PC from internet and NAT takes place at ISA server? I know you told me 1:1 NAT is not supported, but any other work around?

The ISA firewall uses Server and Web Publishing Rules to enable remote access to resources located behind the ISA firewall.

What protocols do you want to use to access the PC behind the ISA firewall?

Thanks!
Tom

I want to connect to my PC directly from home using Remote desktop.

On my home PC I need to open Remote desktop and just use ip address of my pc.

OK, in that case just create an RDP Server Publishing rule.

Make sure the PC is configured as a SecureNAT client.

HTH,
Tom

So I create a publishing rule for my pc?
what IP address do I use from home to connect to my PC at work?
 
Do I need to create a DMZ and put my PC in DMZ?

You need to connect to the address used in the listener being used by the RDP server publishing rule.
