generated firewall

invader44 · 10-09-2009, 11:56 AM

hi,
I got downloaded a generated firewall for my slackware box. Made the rc.firewall and put the srcipt in it and it started it up. But when I try to putty into the slackware box, I can't get in it. I could before I put the firewall on it. Where in that script should I change it, so that it allows me to putty into it?
thanks,
noob

What does your rc.firewall look like?

I believe you have to allow port 22 tcp.

Code:

iptables -A INPUT -i eth0 -p tcp --dport 22 -j ACCEPT

Just note that this leaves you open to external ssh logins, so it makes you more vulnerable.

If you always connect from the same network or host you can add the source -s to the string like this (assuming your local network was 192.168.1.x :

-s 192.168.1.10 for that specfic host
-s 192.168.1.0/24 for that network

iptables -A tcp_inbound -p TCP -s 192.168.1.0/24 --destination-port 22 -j ACCEPT
