The only problem we've had with SNA over IP (Using SNA Tunneling (STUN)) is
that when a controller hiccoughs, our AS/400 won't know there's anything
wrong.  Sometimes we need to vary the line off/on even though it looks as
though everything is up and running fine.  We have to rely on the remote
location to tell us that there's something wrong, and that everyone is
unable to work.

Of course, once we get our network management company on board, they'll be
able to detect the problems and let us know ahead of time.
