Not sure about Vonage, but Skype, Xbox, and just about everything else
imaginable (other than hosting a server) works just fine over NAT with
default-deny inbound here, and we have several thousand students in the
dorms that bang the heck out of those services.  Most applications have
adapted to the SOHO NATing router that is prevalent today on broadband
internet.  And if it didn't work, believe me, I'd hear about it :)
