Hi,
I have dynamic IP on my dsl modem, here is how Ihandle it:
First, here are a few lines from my iptables rules:
(the variable $EXT_IP extracts the dynamic IP)
EXT_IF="eth0"
DMZ_IF="eth1"
LAN_IF="eth2"
LOOPBACK="lo"
#
EXT_IP="`ifconfig $EXT_IF | grep inet | cut -d : -f 2 | cut -d \ -f 1`"
DMZ_IP="192.168.2.1"
LAN_IP="192.168.1.254"
<...snip>
Then I run a cron every 20 minuites to check if it changes,
if it does I update my hostname, restart IPtables and update my DynamicDNS
(these cahnges could be automated but my IP only changes about once a year)
I'll post that script if needed.
Hope that helps.
Pete
