Router port mapping - mysterious ports

[anthill]

Hi,

Not sure this is the correct place to post this. I'm a vodafone bronadband customer and i've noticed some odd port mappings appear automatically without me adding them. These are:

UDP	12022
TCP	12022
UDP	54521

Anyone have any ideas what these are or why they are appearing?

Thanks

It's not causing any issues, it's just worrying why my router keeps automatically opening ports through it's firewall into my network.
