Buy a proper dsl modem+router(+switch if needed) combo.

I'm assuming you've got multiple machines behind the DSL connection,
all NAT'd through the dsl modem machine/router.
If so, you want to do port-forwarding.
If you've only one machine, a DMZ to that machine should work fine.

I still don't fully understand why ISPs use dynamic IPs for
"always-on" broadband, or at least why they don't offer a choice
between dynamic and static.
Marketing spiel could be used on the Joe Plebs to ward them away from
static IPs ie "You'll have only the one address and HAX0RS can keep
attacking you once they've found your IP. Run scared".

It is a major selling point for me if the ISP provides a static IP and
not being able to ssh into a box at home is a pain when you want to do
a quick bit of adminning while you brew a pot of tea in college/work.
