We have currently setup an ISA 2006 server on our new fiber optic internet connection and it is working well. We have an ISA 2000 server on an older T1 connection that we will soon be shutting down. Currently the T1 line is only being used to be a VPN to our disaster recovery site so that email and other important data can replicate to some backup servers located at the recovery site. The recovery site also has an ISA 2000 server.
We will need to upgrade the backup site to an ISA 2006 server. Ideally I want to install ISA 2006 in our main office using some temporary IP addresses. I can make sure it's working by assigning it an unused IP address from our T1 or Fiber connection and setup a separate internal subnet down here.
Locally we use 192.168.1.x and at the backup location we use 192.168.5.x
However in reading up on this I am getting conflicting reports, some people seem to day that ISA 2006 does not like to have its IP address changes after installation and I'd have to reinstall it from scratch when it's at the new location. Is this true? Has anyone setup an ISA 2006 server and later changed both its external IP addresses and internal IP address? I know I would have to edit the rules that were dependent on an IP address but some people say even doing that doesn't solve the problem.
Thanks.
This is being installed on a Windows 2003 R2 server with all current updates.
We have 1 active directory domain, the same one used at both locations.
We're a relatively small company with not that many users, why we even need a disaster recovery fail over site is kind of beyond me anyway.
