A customer has an older Watchguard Firebox X500 Firewall/VPN Appliance and I was wondering if anyone had any luck programming these with a remote VPN phone such as a 5610SW? This will be hooking to to a 406V2 with the latest 4_2 binaries and VPN enabled IP phone binaries. I'd love to put in a NetGear which I've had success with, but they have plenty of port entries for Citrix and the like which they or we are a little concerned about replicating on the netgear. We think they need licenses for RUVPN purchased and maybe an OS upgrade for it for starters.
