This probably needs port forwarding.For that first of all, you need to find which port is used by your p2p software.Lets take example of port number 12086.
1.Open the internet explorer.
2.In the address bar type in 192.168.1.1
3.user name is "virgin" and password is "password".
4.Click on Port Forwarding/Port Triggering at the left hand side.
5.Click on "add custom service".Enter the name of your p2p program.
6.In the starting and ending port, type the port number e.g. 12086.
7.In the server IP address type in your computer's ip address.
8.Click Apply and reboot the router.

This should solve your problem. All the best. :-)
