Pretty much yes, firewalls base definition is around Layer 3, TCP/IP address and/or port #s, and NOT FQDN or NetBIOS name, if that’s what you’re asking.

' From: David Lum [mailto:david....@nwea.org] Sent: Friday, January 07, 2011 9:54 AM To: NT System Admin Issues Subject: Firewall Q Dumb question but I have to ask. Firewall rules are by and large IP specific right? For example, if I have a rule that lets a machine talk to Windows server at 10.100.10.100 I should be able to flip any server to that IP and access should work right? Specifically I have an RDS broker server that has a firewall rule for a DMZ system to hit it, I could build a new RDS broker and just assign it 10.100.10.100 and effectively replace that server on the fly, right?
