What ports? I haven't looked in well over a year, but at the time I
found nothing useful on the Vonage site or the web as to what was really
needed. I finally just ran it for a few days with logging and fiddled
it from there.
My Vonage adapter is the only device on a cross-over cable on it's own
firewall interface, with incoming UDP NAT/rules as follows and outgoing
from that segment wide open (where vonageext is an alias to my devices IPA):
Prot Src Port Dst Port Desc
UDP * * vonageext 10000 - 20000 NAT Incoming Vonage ports
UDP * * vonageext 69 NAT Incoming Vonage TFTP (update) port
UDP * * vonageext 65535 NAT Vonage VoIP adapter (not sure this is
needed)

Also, at least for me, every time they flash the box it resets to
default, killing my incoming SSH NAT. NOT cool. NOT acceptable.

The only problems I've ever had, running on both Comcast and FiOS 15/2
are switching issues at the Vonage server end (i.e. the number I dial
isn't the number I get connected to).

Microsoft has single-handedly nullified Moore's Law.
Innate design flaws of Windows make a personal firewall, anti-virus
and anti-malware software mandatory. The resulting software arms race
has effectively flattened Moore's Law on hardware running Windows.
