allow p2p access through SQUID

hi
i wanna change the squid.conf to allow users download through p2p
I know that i should open some ports to allow p2p access through SQUID, but do not know exactly what ports and where :(

Code:

---

acl SSL_ports port 443 563
acl Safe_ports port 80        # http
acl Safe_ports port 21 20    # ftp
acl Safe_ports port 443 563    # https, snews
acl Safe_ports port 70        # gopher
acl Safe_ports port 210        # wais
acl Safe_ports port 1020-65535    # unregistered ports
acl Safe_ports port 280        # http-mgmt
acl Safe_ports port 488        # gss-http
acl Safe_ports port 591        # filemaker
acl Safe_ports port 777        # multiling http
 
....
http_access deny !Safe_ports

---

all the needed ports for p2p are in # unregistered ports range (emule, torrent)
and "http_access deny !Safe_ports" denies all ports except Safe_ports, anotherwords - allow Safe_ports only!

So using that config should allow users to use p2p connection? Am i right? If not, what should i do to allow that?
