In my experience, embedded systems tend to behave poorly when faced with large amounts of traffic (normal traffic to these systems is tiny). I have once been locked out of work due to an errant workstation flooding the network with broadcast DHCP packets, which overloaded the embedded system which validates the key cards and unlocks the door (later permanently solved by moving the embedded system to its own firewalled VLAN). As an aside: lovely Netscape favicon on that site.
