My 2 cents
I identify in my firewall script my dsl interface by it's interface name. Nothin else comes accross that way. Who cares of it's IP ? Tell me if I'm wrong.

You just need to capture your dynamically assigned IP address at iptables startup time and use it in your rules. I have the following variable assignment in my RH 7.3 startup sdript (all one line):
INET_IP=`ifconfig eth1 | grep 'inet addr' | awk -F":" '{print $2}' | sed 's/
Bcast//'`
Then just use $INET_IP in your rules.
