Ah, back in the day of M$ Win, i'd have suggested Kerio or Commodo. Once
they're installed they listen and then report on new network connections
and allow you to build the firewall ruleset on the fly by allowing or
denying each newly learned network connection.

The most functionally similar FOSS firewall I know of is
http://gufw.org/, which is a GUI front end to Uncomplicated Firewall (
https://help.ubuntu.com/community/UFW). Gufw does have a listening report
hat allows you to see active connections.

You can create rules from a preconfigured list of commonly known programs
such as amule and by service name such as ftp, ssh, etc since ufw reads
from /etc/services.
