You can write a rule to block ports 6881 to 6889 in a firewall (such as Firestarter (https://help.ubuntu.com/community/Firestarter)).

This should do it in iptables (https://help.ubuntu.com/community/IptablesHowTo), which is more the hacker approach:

iptables -A INPUT -d localhost -m multiport --dports 6881-6889 -j DROP
