A NAT that if it's external IP was 1.2.3.4, any time it saw the binary
pattern 0x01020304 passing through it in any data it would replace it
with the nats internal IP. (Many NATS call this "feature" a "Generic
ALG" so if you see a NAT with that, run screaming) Most stuff worked
fine but the bug was found when someone was downloading the ISO image
for a Linux CD that just happened to contain the external IP in some
executable that got changed in the download. Credit to Adam Roach for
figuring out what was going on.

As part of a research project, we are working on automated
diagnostics of network-related faults in residential, SOHO,
conference/special event, hotel and similar networks. If you have
observed errors that were hard for a lay person to diagnose, whether
due to end system problems, NATs, LAN or Internet issues, please
send me a brief description. (Also, contacts in tech support for
such environments would be most helpful, particularly if they might
be willing to talk to us.)
