The best way (IMHO) to check on the security of your DSL setup would be 
to run something like nmap against it from the outside.  See what ports 
are open..   (any BTW, you'll have to open port 80 for your webserver 
and you need to find out how to do that)

I have DSL from Ameritech and the modem itself was just that: a modem 
with only one port and no firewall.  Adding a Linksys Router added the 4 
ports and a (seemingly) very good firewall...  hopefully your modem does 
all that as well.
