[OpenAFS] Multiple hosts behind firewall and AFS cell

[Turbo Fredriksson]

I have a number of machines at home which I can log in to.

If I login on multiple machines, the previous host looses 
connection to the AFS file server.

Example: 
        1. Login in on host1. Homedir on AFS.
           Works fine.
        2. Login in on host2. Homedir on AFS.
           Works fine - BUT: host1 looses the connection
           to the file server!


The firewall is a Linux machine, doing NAT (masquerading).

Is this supposed to happen?
