Dialup or DSL doesn't matter. What matters is your firewall filtering
rules and the services you advertise to the internet. Linux does an
outstanding job of this. I run a Coyote firewall on the 486 with no hard
drive on a DSL line. No problems.
Consider this: a large percentage of the internet runs on Linux servers.
If it's good enough for machine sitting directly on the internet, it's
certainly good enough for your firewall.
