Cannot make utorrent connectable behind router

[dcsquare]

I have a WRT54GL and an AT-AR221E. On both I tried port forwarding and DMZ.

If I use another application (for ex an ftp server) on the port used by utorrent, it's listed as open on the utorrent testport page.

If I use utorrent, the port is no longer listed as open, and utorrent has the red exclamation mark.

I'm using Vista Ultimate SP1, with the firewall turned off. No firewall is turned on in the router either.

Any ideas? Cause I've sure run out of ideas after 1 week...

Plesae post a HijackThis log.

And if you're forwarding manually, try disabling UPnP.

[dcsquare]

UPnP is disabled. I don't usually use it.

It's probably Avast's fault. It can act like a firewall under certain circumstances and is likely blocking µTorrent from listening on any port.

[dcsquare]

Tried with avast and Windows Defender turned off. Same result.

The problem is that if I connect the computer directly to the cable modem, I'm connectible.

That's why at first I assumed a router problem and I changed my old AT-AR221E (that's been working fine for the past 4 years) with a brand new WRT54GL, but the problem remained.

And yes, I did forward properly the port (an ftp server on the same port works just fine).

[Firon]

I don't think disabling Avast will work... probably only uninstalling it. You can always reinstall it if I'm wrong.

[dcsquare]

Uninstalled avast and still the same problem

[Firon]

Try enabling the built-in Vista firewall again and reconfigure it to allow µTorrent.
