I am trying to forward port 5900 so that I can use VNC, but I can't seem to get it working.

I have a static IP from my provider. THe Vonage vdv21 is configured with my Ip's information. When I got to the port forwarding section it gives me the option to forward ports on 192.168.15.?? starting at

My router is plugged into the Vonage box and it has obtained it's IP automatically, but it has as it's IP.

How can that be?

My PC is plugged into my router and it obtains it's IP automatically from the router and it has

Before I installed the Vonage box, VNC worked fine when I told my router to forward port 5900 to Now that I have installed Vonage, it won't work. Even when I tell the Vonage device to forward port 5900. But it only gives me the 192.168.15.?? option.

OK so here is what you have.

Cable Modem assigns ISP Public IP to Vonage adpater

Vonage adapter assigns a Private IP to your router's WAN / Internet port.

Your router assigns to your PC.

The reason your having difficulties is because the machine your want to reach is behind 2 separate NAT firewalls (2 separate networks). In order for you to reach your PC, you will need to traverse each NAT with it's own port forwarding rule. By doing so, when the VNC packet request from the internet reaches the WAN port of the Vonage adapter, it will have to be forwarded to the WAN port of your router and then forwarded from your router to your PC's private IP address.

If you follow the steps below I have drawn out for you, this is a simple task.

Step 1: Log into your router at
Step 2: Go to your router's Status page and find out what IP is being assigned to the WAN / Internet port. Should be or .3
Step 3: Write down this IP address, subnet mask, default gateway, and DNS server found on the status page.
Step 4: Go to your router's internet connection settings and choose Static IP from the list.
Step 5: Configure a Static IP using the same information you just wrote down.
Step 6: Save settings and confirm your PC still has internet connectivity. If not, go back to to the Setup and make sure you entered all the information just as you had written it down from the Status page.
Step 7: Go to your router's Port Forwarding section and enable Port forwarding to TCP port 5900 - 5901 to your PC's IP address of
Step 8: Now log into the Vonage device at and go to the port forwarding section.
Step 9: Configure port forwarding for TCP ports 5900 - 5901 to your router's IP of 192.168.15.x (This is the IP you statically assigned your router - x is only a representation of the real number unknown to me)
Step 10: Save settings
