Hoping this is the last question of the day :)  In our current firewall setup we reference one IP via a DNS name - for outside access.  I can't see a way to do that in the Cisco ASA - everything I've heard is that everything needs to be referenced via IP.  The only problem is I think this IP changes occasionally.  How do I best address this?  Perhaps let that particular outside machine access 'Any' for destination on a particular port?

That's what I thought too.  I'll just allow 'any' and specify only a certain protocol for that machine.  Thanks!!
