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. Ted

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. -Ryan Adams Free Computer Tips and more:http://RyanTAdams.com Paid Tech Support: Black Diamond

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)? -Ryan Adams Free Computer Tips and more:http://RyanTAdams.com Paid Tech Support: Black Diamond

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. -Ryan Adams Free Computer Tips and more:http://RyanTAdams.com Paid Tech Support: Black Diamond

Alright, thank you. =] I'll attempt your suggestions and see if I can get it to work. Thank you so much for your assistance. IAR
