Unusual was my first DSL setup, many years ago. My ISP even let you
run servers and provided DNS service if you had your own domain
name. I had a P-75 running as a combination of firewall, web server,
and relaying mail server. It also did NAT.

I would not consider such a setup secure now days, but the risk at
the time was acceptable.
