   I passed your question along to a friend of mine who is (IIRC)
running a Cisco ATA (Vonage) behind his firewall.  Hopefully he'll
have a better answer.
   When I got my Vonage service (with the newer Motorola hardware)
they included instructions for running behind a Linksys router.  It
amounted to forwarding the following UDP ports from your firewall to
the VoIP box: 53, 69, 123, 5060, 5061, 10000-20000.  I know you can
safely eliminate 53 and 123 from the list, but I'm not sure about the
others.  There might be a valid reason they need TFTP (firmware
updates), and I don't know enough about VoIP to mess with the other
ranges, yet.

A fool must now and then be right by chance.
