Another problem I've found with commodity firewall/router boxes
is that they tend to have dhcp enabled by default which can be
``interesting'' if one already has a dhcpd or bootp server on the
network. This bit me a couple of years ago when we installed a
LinkSys BEFVP41 VPN box on a network where a Linux server was
running bootpd servicing diskless workstations. I had forgotten
that bootpd and dhcpd run on the same port.
