I am running an IPCop 1.3 firewall/router
it is set so that http://192.168.1.1:81
is my default administration for the webGUI
it also seems to be open for remote administration on 81 from outside my network
Anyways if I wanted to block outside access to 81
would this be Appropriate for doing so.....
iptables -A INPUT -s ! 192.168.0.0 -p tcp --destination-port 81 -j DROP
