This might solve a problem I have. Some of my users have portables
which talk to our network via direct ethernet or via dial-in slip with proxy
arping. For various reasons, I'ld like them to use the same IP address no
matter which method they use. The problem is that if they switch from one
to the other quickly they have problems with the ARP tables in various
machines not having timed out yet. The result is that when they try to
connect to one of these machines via the new connection, the target machine
has the old ARP entry in its cache and sends responses to this connection
attempt to the wrong ethernet address. It took me a while to figure out
what was going on the first time it happened...
