Re: [Equipment] Vonage RTP (Voice) Traffic port forwarding on AS
I have not taken delivery of the V-Portal as of this writing. I am configuring my firewall based on the Vonage published instructions titled Advanced Installation with Port Forwarding. According to this document "If your Vonage adapter is located behind a routing device that has firewall capabilities, and you do not wish to reconfigure your network, then that routing device must be configured for port forwarding for Vonage service to operate". The instructions require the V-Portal to be configured with a fixed IP address, lists the outbound ports that must be permitted (I don't block any outbound ports) then state "The following ports are needed for INCOMING and OUTGOING Internet communications from and to Vonage devices and servers. RTP (Voice) Traffic: Ports 10000-20000 UDP". The requirement is pretty explicit. I can't imagine why Vonage would publish such a document if it weren't necessary. Am I missing something? |

| I very much doubt you'll have to forward any ports for Vonage to work. It deals well with NAT in most cases without any special accommodations. Just give it a try before worrying about it, odds are excellent it will work just fine. If you do have to forward some ports, that whole 10,000 port range for RTP traffic is NOT needed. I'd Wireshark'd a lot of Vonage calls and never saw it go past port 10,002. |
