I have a Compaq Deskpro running Red Hat 9.0.
I have used Fwbuilder to compile a set of rules, so that I can use this machine as a firewall. When I apply the rules "./rules.fw" the firewall works fine, I can get all outbound traffic.
I have set the rules to start on startup "/sbin/iptables-save > /etc/sysconfig/iptables" however when I reboot the machine, I get no outbound traffic.
It appears that routing is enabled, as even though I can not get on to the internet, I am able to ping through the firewall to the external IP.
If I restart iptables ...... nothing
If I manually apply the rules, works fine.
If I then restart iptables, works fine?
I have checked to see if the rules are loaded "iptables -L" and they are there after the reboot.
Not sure what's going on.
Any help would be appreciated
Thanks in Advance
