Hi there folks, Just a quicky. I've been mucking around with iptables for a while, but I'm still a bit shaky with them. Would anyone mind checking this over for me please?
I want to be able to accept incoming connections on port 22, accept any connections which are a reply to a connection that I have initiated to an outside TCP address, but other than that, I want to drop all other TCP connections coming in. Does this look right? On a side note, I've added a symbolic link called S95firewall to this script in /etc/rc2.d/, but it doesn't seem to run this script at startup? Any ideas what I'm doing wrong? Cheers Chris echo "Applying firewall rules" iptables -F iptables -A INPUT -p tcp -i eth0 --dport 22 -j ACCEPT iptables -A INPUT -p tcp -i eth0 -m state --state ESTABLISHED -j ACCEPT iptables -A INPUT -p tcp -i eth0 -j DROP echo "Rules applied"
