Iptables

Virtuozzo iptables firewall

Recently I got chance to play with Virtuozzo VPS. Good news is they are good to reduced cost and bad news (as of Dec-04, 2004) they do not support full iptables rule set like –state and –log etc. After spending more than 4+ hrs I was able to setup simple but effective firewall on Red hat enterprise linux Virtuozzo VPS. Here is script. Make sure you customize it for your environment.

Sysadmin because even developers need heroes!!!
