Your dhcp client should have a way to run a command every time the ip changes or is renewed. For dhclient (pump and dhcpcd didn't work well with my ISP) it's /etc/dhclient-enter-hooks. Be sure to check if the IP has really changed or if it's just a license renewal. You don't want to be reseting your firewall every ~30 minutes. > TIA, Simon.
