iptables assistance
I have a CentOS 5.2 (10.20.21.73) machine that I need help with configuring iptables. According to documentation I believe this line should allow all communication between my machine and another machine (other machine has no firewall)
-A RH-Firewall-1-INPUT -s 10.20.21.12 -j ACCEPT # /etc/sysconfig/iptables *filter :INPUT ACCEPT [0:0] :FORWARD ACCEPT [0:0] :OUTPUT ACCEPT [0:0] :RH-Firewall-1-INPUT - [0:0] -A INPUT -j RH-Firewall-1-INPUT -A FORWARD -j RH-Firewall-1-INPUT -A RH-Firewall-1-INPUT -i lo -j ACCEPT -A RH-Firewall-1-INPUT -p icmp --icmp-type any -j ACCEPT -A RH-Firewall-1-INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT -A RH-Firewall-1-INPUT -s 10.20.21.12 -j ACCEPT -A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 22 -j ACCEPT -A RH-Firewall-1-INPUT -j REJECT --reject-with icmp-host-prohibited COMMIT |

Fixed
Ahh, after much fiddling around with different configurations, I found the answer.
Needed my subnet on the source, 10.x.x.x/255.255.255.0 solved the problem. |
