Hi jake.
Because you have moved your computer Im hoping your router just needs reconfiguring, this link will open on the page of your router setup
even if the settings look OK re apply them all, Dont forget to create a static IP
& apply, before portforwarding. For ports, use numbers above 45000 to 64000

Also, Delete & re apply L/W permissions in Zonealarm FW.
P.S.. Was this problem happening Before you moved computer ?
Have You been using L/W or another P2P program allot lately ?
Answer Qs and tell us how you get on.
Peace.
