IPkungfu on debian
I have installed debian 3.0 with kernel version 2.4.18 and IPmasq. I want to use this machine as internet gateway with firewall.
Mchine works fine as internet gateway and i m trying to install ipkungfu as firewall.
How can i disable or enable the outgoing ports so that interanet PC's can only access the gateway which has been specified or can not access which has been put in denial list??
for example: i want to disable the port 21 so that no machine/application in interanet can access the port 21 through gateway and want to enable the port 80 so that all machines in interanet can use HTTP ports.
Can any body give me some idea??
Thanks in advance
