I need to open a port on my cable modem

915 Views
Last Modified: 2013-12-21
I was told by my firewall company that the cable modem (from Comcast) was blocking access to a given port, which they have verified has been opened on the firewall.

Does anybody know how to open a port on a Terayon TJ715X?

I get some hits from a Google search Terayon tj715x "open port"  but can not find anything that helps me do it.

If you have an idea, I'd love to hear from you.

Do they have a firewall in their facility for me?

I have Comcast and am testing this without any firewall, just the Terayon TJ715X cable modem.

Please advise...

I am running Windows 203 Server

I do not have Windows Firewall turned on.

The service is a C#.NET web service.

I could use a different port number if I could find one that can provide acess to the outside world.

I have been using port 9091.

The web service was accessible to computers behind the firewall with :9091 appended to my local IP address, when I had my firewall hooked up.

I just removed the router so I can have direct connect, just to reduce to a minimum.

So the machine will be down a minute...

I rebooted with a direct connection to the cable modem and the Internet's working.  But 9091 is still failing.

some of the settings have changed:

I decided to host this web service at an ISP that can handle these kinds of problems for me.
