Ugh...so that is where RH-Firewall-1-INPUT comes from...I thought it was
FW-Builder or something that creates this crap.
It's not very fancy. I just use the GUI tool to open port 80, the ssh port
and then the samba ports (137-139 and 445).
Hmm, no port 80 rule below but whatever...
After a reboot or perhaps just a 'service iptables restart', does
'iptables -L -n' list the rules you have below that are stored in
/etc/sysconfig/iptables?
[root@myhost ~]# cat /etc/sysconfig/iptables
# Firewall configuration written by system-config-securitylevel
# Manual customization of this file is not recommended.
