Hi. If there are specific ports being blocked it is possible your firewall setup needs to be changed. If using Windows Firewall on Windows 7 or Server 2008 there are significant changes with advanced firewall rules. If earlier there are still rules that might be blocking. If using a firewall application then this needs to be checked as well. It is possible that when you started using this connection, a pop-up message appeared asking if you wanted to allow or block this connection, if blocked it would have set a rule.

sounds almost like you have it wired improperly. double-check the physical connectivity of your devices – if your PC is plugged into the WAN port of your router, and the internet connection is on the “LAN” side, it would certainly explain this issue…

Even after resetting also same problem. Reset means what will happen i think nothing. The settings will be same i think so.

Try resetting the router. It sounds like some how the port forwarding is corrupt.

Hi,
Thanks for your response. IE is allowed in my firewall list. Normally IE use 80 only ok. But the problem here is local computer uses random port to connect to internet and reply for the same port through which it connected. But here means in my case i am sending in one port but getting in another port. Where the problem could be?.
