Listen port blocked(unable to open lisen port recently)

My bitcomet version is 1.25,and os win XP SP3,connection type ADSL.

I had managed to open the listen port before and was working fine for many days, but now from about 3 days i am unable to open it, it shows listen port blocked. Before the port was 16639 and now i tried to open by adding different ports after 16639 was blocked, but still i am unable to open it.

please help.

thank you.

How did you open it before?

Please read here, and come back with the details.

I had read those before and opened it…just a while ago i noticed that my lan IP has changed form xxx.xxx.x.2 to xxx.xxx.x.5 could that be the reason.

Yes, that’s the problem. When you forward a port in your router you also need to choose an IP address, it stays open for that IP address, but when your computer asks for a new IP address, the router has no port forwarded for the new IP address so all (0-65535) ports become “Blocked”

The easy way to fix this is to use this app. Then you’ll need to forward your port again for the new, static, IP address.

thankx…now i am able to open it. :smiley:
