It depends on your setup.  If you are doing address translation then you must have it enabled.

If you are not doing address translation and do not dynamic port allocation (basically if you have permit ip any any) then you need to have it disabled.

So, engineer's favorite answer - it depends.

Are you referring to turning it on or turning it off!

Subject: [cisco-voip] VoIP over Hardware VPN

VoIP over Hardware VPN Anyone have any hints, tips, suggestions, comments, concerns, etc., regarding running a single IP phone over a hardware-to-hardware VPN.  I've tried it in the past but could only seem to get voice going in one direction.  It's been a while and I'm going to give it another shot.  Will be working with ASA 5505 on one and ASA 5510 on the other.  Call Manager 4.x.  Probably a 7940 or 7960 phone.  Internet connections are 15-Meg-Over-Ethernet on one end and 10-Meg-Over-Ethernet on the other.  Current ping times between devices on the two ends are consistently very fast -- less than 100ms over extended ping tests.

Any advice, anecdotal wisdom, personal experience, etc., that anyone has had in trying to do this is sincerely welcome and appreciated.

Thank You...
