Um. Presumably that would work for multihomed computers (ones with two
network connections: in this case one to the Internet and one to the
local network).

If the server is behind a firewall that does one-to-one NAT (all
connections to an external IP address get forwarded to this computer),
or if the LAN IP address is itself routeable (used to be common, and
still exists), then people outside the LAN would still be able to
connect to a vsftpd listening on its LAN IP address.

In this case, I'd look at firewall set-ups: ideally one on the computer
and one in the vicinity of the router (exactly where depends on your
network setup).
