khayulay, yes it worked fine. The VPNremote software seems to be completely independent of the rest of the phone operations, so I think its pretty transparent to what it connects once the VPN network is up. Yeah I guess Avaya doesn't support this, my Tier 3 Avaya IP Office guy didn't even know about this new feature. The Avaya data director here in Mexico wasn't better off either! Well what a surprise hehe. I'd rather have them concentrate on working on basic reboot and reliability bugs right now.
I tried it on an SG200. I guess it could be possible to have it work on other firewalls but who knows.
