Welll, I sort'a fixed it. For some obscure reason the X2100M2 ILO will
not run when placed behind a Cisco PIX firewall, even when the firewall
is permitting all ports & traffic in and out. Very strange and not
really what I was expecting. The X4100 ILO runs great, even using NAT
on that...

Does the ILO (I guess this is the name for the console app?) use UDP or
TCP? If TCP, I wouldn't expect a problem but if UDP, it might be the
case that instead of sending MTU-sized packets, it sends larger packets
as fragments. TCP shouldn't do this because packet size should simply
be limited by MSS/MTU.

The problem with fragmented packets and firewall is that Linux, which I
am just assuming is the OS for the ILO, sends fragments backwards --
last fragment first -- as an optimization. This breaks stateful firewalls,
which includes NAT even without any firewall rules.
