I am building a firewall with iptables. There are some checks I'd like to occur on multiple chains. I'd like to arrange these as a "subroutine chain", i.e. a chain that is called and then returns to the calling chain if the packet makes it to the end. Schematically...
iptables -A FORWARD -j CHECKS iptables -A INPUT -j CHECKS iptables -A CHECKS ... iptables -A CHECKS ... iptables -A CHECKS -j RETURN Yes, I know I can make it work by just reproducing the CHECKS rules in each chain, but that's not good programming practice. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
