I am configuring a firewall that will run dhcpcd on eth0 (it is connected to a cable modem).
I have a firewall rule set (for IPTABLES) that is working on another machine with a fixed IP for eth0 In the rule set I have statements such as IF_INTERNET="eth0" IP_INTERNET="24.27.45.111" I use the $IP_INTERNET value in $IPTABLES -t nat -A POSTROUTING -o $IF_INTERNET -j SNAT --to-source $IP_INTERNET to give me my NAT translation. My question is this --> How do I synchronize the IP address for eth0 that dhcpcd secures with the rule in iptables? It seems to me that I need to run some script or take some action each time dhcpcd secures a new IP address. Thanks! -- Randy
