Setting up Bittorrent on Technicolour Router - Plusnet Fibre

[#1]

Hi guys,
I got my Technicolor router and my Plusnet Fibre setup yesterday. All is working well.
I'm part of a network that actively share and host ISOs and we share them over BitTorrent (these are legal torrents).
In the router i have added the "game or application" and assigned to a computer. I have setup these ports to communicate over TCP and UDP and assigned that port in uTorrent however I still cant get uTorrent to allow on incoming connections.
UPnp is also turned on.
Any ideas?
thanks

Are you doing manual port forward or UPnP
I don't know much about the router as I use aftermarket routers but... if doing manual port forward (like your post implies)
Is Utorrent set to a specific port number and not randomise port?
Which port number are you using? It could be another problem is interfering with it and using the same port.
You've set up a Static IP (if required) for your PC?

You need to check a few things:
Is utorrent using upnp? if so remove the manual port forwarding you don't need it.
If not:
Static (fixed) port ? If so make sure the port numbers are the same on the router and you have both TCP & UDP allowed in to that port.
Dynamic port - you need to use upnp.
