Vonage It has nothing to do with the port. The source port of your device for the SIP protocol



It has nothing to do with the port. The source port of your device for the SIP protocol is 10000. The destination port for the SIP proxy is 10000. The firewall is not blocking based upon IP or port. It is inspecting the packet and does not like the algorithm so it blocks it. This is because it has an Application Layer Gateway which finds the SIP protocol and tries to perform what is believes is a help mechanism but actually breaks it.

Your device will send out a Register every 20 seconds and under normal conditions will get a response back. This what keeps the NAT pinhole open. However, your SBG-900 is not letting the response pass back to the Vonage adapter. This is why port forwarding does nothing to help.

Port forwarding is used when a service is idle and just waiting for a connection. When a packet arrives from outside your NAT firewall on the Public IP, the NAT table will know how to translate that packet back to the Private IP of the host machine for the service because you told it where to go when a certain port was hit on from the outside.

So since the Vonage adapter sends out a Register packet, it is the same as you opening your web browser and going to google.com. Packets are sent out and come back in through the same pinhole. This is why you don't have to forward port 80 to establish an HTTP connection and why it is not needed for Vonage.

However, because your firewall is doing something based upon the SIP protocol, there is nothing Vonage can do to assist you. Should you choose not to completely disable the firewall, the service will not work.

I have been with Vonage for 6 years and am one of the approvers of placing the SBG-900 and SBG-1000 on the problem hardware list and making the only workaround disabling the firewall. This has come from seeing numerous customers over the years run into the same issue when using these modems. Even if by some mystery you were able to get it to register and get dial tone, in a few days, weeks, or months from now, something would trigger the firewall to start blocking SIP again leaving you without dial tone. In addition, the SBG series firewall will also cause no audio or 1 way audio conditions. I assume the difference in the customer experience is the firmware on the SBG modem.
