Hello ,
I already install RH. 8, with 2 interface (eth0 10.10.10.8), (eth1 192.168.1.1), i want blocking mirc, messeger. I type this command
/sbin/iptables -I INPUT -i eth0 -p tcp -s 10.10.10.8/32 --dport 6667 -j DROP
Few things that you may interested to know
Not all IRC server use listen at port number 6667 Are you using a proxy?
My suggestion to you that is that instead going in this way, identifing the services you dont want to allow, identifing the services that you want to allow and disallow the rest of them.
Hope this helps.
