You probably did launch 5 independant ssh connections, not 5 sessions using the same connection. MaxSessions is the maximum number of sessions a user can use in a single connection, using multiplexing (see ControlMaster, ControlPath). Look again at the definition of MaxSessions, it is talking about network connections, not network address. > My question: > Is 'Match' used as a further refinement to any of the rules listed in > the keywords section (see last paragraph above), or is it required in > order to use one of those keywords?

I think you want firewall level features (hint : max-src-conn).
