BT can you please open port 80 was working with utorrent, no more.

[reece71079]

I was using port 80 with utorrent, seemed the only port that would work with it. But now it must be closed because it does not work on that port anymore. Im not using it for another reason, so please open it. Getting fed up with BT Business Broadband I always seem to have a problem. Actually I will note them:-

1st. Speed issue - stuck at 1152kbps line capped.

2nd Modem keeps resetting after about 10 to 12 days of it being on.

3rd Cannot open a port fully for utorrent, 80 was working fine but they have closed it.

Thats about it.

Nope, it's now up in the loft since I'm never going to use it.

Is there no firewall configuration on the router's setup pages?

All the routers I've owned in the past that have firewalls built in block ALL incoming traffic (which would include port 80). You have to specifically open the ports you want to. The NAT functions of more recent routers has made this a non-issue for most users, but perhaps these BT routers have dodgy NAT functionality.

I, and others, have tried that and also used the BT support desk - we cannot get it to work!

Previously on ADSL (all flavours) it was fine.   On VDSL it fails!   Take my PC to an ADSL connection - it works, bring a PC from an ADSL connection to mine - it fails!

I don't suppose you have an alternative router to try?

I got my BT hub out of the loft. 

As I suspected, it has a built in firewall which will block all ports by default.

It's easy to set up specific services though.

In the "Firewall" tab, "Allow Applications, Pinholes and DMZ Mode " section, firstly select the computer you want the port opened for. Then tick the "Allow individual application(s)" option. Select the "Servers" tab and select the "Web Server" option and send it over to the box on the right. Then remember to save it.

That enables port 80 to be 'port forwarded'.

If necessary I will try and investigate further as to why the UPnP / NAT-PMP functionality either isn't working or isn't present, but that should satisfy this one for now.

UPnP is not supported on the BT Business Hub.

Thanks John, so the guys who want to use P2P software and have a port open need to ensure they manually open it (via the method above).

I'm assuming that at some time port 80 was open and that a firmware update to the router at some point closed it (quite rightly in my opinion).

It seems to me that it's not that clear cut.  Port 80 is, after all, the port which handles http: traffic.  If you set up port forwarding in the Hub, does it resolve the problem?
