Greetings,
I am sorry if I repeat any thread in forum, but i need some help quick.
Runing slackware 10.2 kernel 2.6 as a router
external interface - eth0
internal interface - eth1
subnet - 192.168.0.x
I am still relative newbie to linux and trying to configure IPTABLES.
My goal is to make that:
1) All external connections to port 22(ssh) would be dropped, while connections from internal network it would be open. My rule for this is:
iptables -A INPUT -i eth0 -p tcp -m tcp --dport 22 -j DROP
2) (which is actualy my current problem!!!) I want to make that if trying to connect to my router using port 2222 (not 22) it would somehow forward request to port 22 and allow a connection. (Some sort of tricky hiding
)
Thanks
Kandzha
