Do not regard a modem/router as a firewall, unless it specifically
offers that feature, and you enable it.  I've seen a few that try to be
helpful and pass incoming connections through to the LAN (so that
clueless users can swap files, etc., without needing to know anything
about special configuration of their gear).

(This box runs FC6, my others run FC4 & FC5, in case that's
 important to the thread.)

Don't send private replies to my address, the mailbox is ignored.
I read messages from the public lists.
