Export ISA 2006 config to new server with blank ISA install but now we have a problem

Hi, We are moving our 2006 ISA server which is configured as a publishing server for 10 applications which is internet facing to a new DMZ. The current server has 10 internet published IP addresses which are bound to the NIC, one IP address per application.

What I have done:
Built a new 2003 server and assigned the new 10 (natted) IP addresses to the NIC, installed ISA 2006. Exported the ISA policy from first server and imported to second server - all looks good.
I now need to change the listeners foe each app to point to or rather listen to one of the new ip addresses but I can't. When I access the "external" node from within ISA it is still showing me the IP addresses that were configured for the other server. It has remembered the IP addresses but I can't seem to see any way of removing them and adding my new IP address. Any ideas much appreciated.

Is it still an issue?
See if this helps to change the ip addresses.
If you have one network card and one ip address bound to that network card already, you would have a file in /etc/sysconfig/network-scripts called "ifcfg-eth0".
This file contains the configuration for that network card.
If you want to bind more than one ip address to the card you need to create an additional configuration file for each of ip addresses that you wish to add.

@Merete - This is a Windows server, not a Linux box :-)

@JasonHels - You need to do three things...

1] Add the old IP addresses to the external NIC on the new server, then restart the Firewall service or restart the server
2] Reconfigure the listeners for each application to use the designated new IP
3] Remove the old IP addresses from the external NIC then restart the Firewall service or restart the server

You may need to take the new ISA server offline and connect it to an isolated switch to do this, as you may otherwise cause an IP conflict.

Hi craigbeck, sorry for the late reply. I understand the explanation but here's the thing....  The old IP addresses that were bound to the NIC prior to exporting the config are in fact not bound to the new NIC? So, Although i can do steps 1 and 2 I can't do step 3 and here is my problem.
Craig BeckCommented:
I see what you're saying, but that's why you have to re-add the old IP addresses, even if they're not being used.

The old configuration thinks that the old addresses are still there, so you need to put them back, then reconfigure the rules/listeners with the new IPs, then remove the old ones from the NIC.
