Port 9339 is blocked by my router.

Specs: Windows XP
We recently purchased a Motorola SBG900 wireless gateway router. However, I am now having trouble with some online applications. Whenever I try to use a specific one, it says I cannot access the server because port 9339 is blocked. I've forwarded the port on my router, but the firewall is still blocking it. How can I fix this? Thanks.

Are you sure it is the router that is blocking it and not a local firewall or something else? Make sure you set up port forwarding correctly, and that should be all you have to do.

First of all, thank you for the response.

Second, yes I am sure it is my router. I've never had this kind of problem until last Wednesday when we got Charter highspeed and hooked up our router.

Also, when I forwarded the port on my router, I got a message telling me to 'don't forget to allow access to port 9339 on your firewall'.

What application are you trying to use? Did you switch to a new internet service provider? Is it possible they are blocking the application (many block web server, ftp servers, etc. from being accessible on their residential service packages)?

I'm attempting to use a flash poker application on Facebook. (trivial, yes, I know. But still frustrating.) We just switched ISPs a week ago to Charter Communications. I highly doubt they are to blame. I narrowed the problem down to my router firewall, because when I turn it off, I'm able to use that port.

I'm not familiar enough with that router to give you very detailed information, but the follow generally applies to any router:

When you set up the router as a DHCP server for a private LAN (as in, each computer receives a LAN IP such as 192.168.x.x), the router is performing something know as NAT. This in many ways behaves as a inbound firewall. This is what creates the need to "forward ports". Some routers also have a firewall, which checks inbound and outbound data. If your router is performing NAT and also has a firewall, you will probably need to both forward ports (for the NAT) and to adjust the firewall settings to allow your data through.
