Hello,
We have just run into this problem but in a very difficult situation to
diagnose!
For a start, we are running a director based on a cut down Mandrake 9.0 (see
loadbalancer.org) with Windows 2000 real servers.
I am curious, should I adjust the MTU size on the director only, real servers
only or all machines?
TIA
Chris Paul

Joe,
typically the MTU used is 1500 bytes. But when tunnels come
into play then this becomes slightly smaller because of
the overhead for the tunnel. This should not be an issue
but in practice it offten makes sense to manually set
the MTU to the smaller value on applicable interfaces.
