I am a regular reader of this list and I have absorbed that most of the users won't use the source ports in their rules. Say for ex,
#iptables -A INPUT -s 192.168.1.0/24 -p tcp -d 0/0 --dport 23 -j ACCEPT
In these kind of rules they will not specify the source port from 1024 to 65545. I strongly recommend all Linux Users to specify the exact rules what is allowed and what is not allowed.
Any Comments? This could be a good practise?
