[OpenAFS] AFS-Client behind masquerading firewall

[Jim Rees]

  A slightly different twist -- on our campus, we have dual-boot linux/NT
  boxes in our labs, which all run AFS.  Due to this problem of having "two
  clients" on the same IP, we run into servers getting confused all fo the
  time.

We do this too and have never noticed a problem.  If you reboot a client,
the server might try to return a callback that the (rebooted) client knows
nothing about, but it just gets ignored.  What sort of problems do you have?
