I use MDK 9.1 with the Shorewall firewall configured to reject any
incoming communication from the Internet.
As my son wants to use a peer-to-peer application (mlDonkey)
I'll have to add some rule to allow (only) that specific incoming communication.
In order to maintain max security I have created a separate user,
named "Joe", and intend to run mlDonkey while Joe is the only user
logged on. Is there a simple way to modify Shorewall's rule file
while Joe log on and restore it while he logs off?
Thanks in advance....
