Yes, and that's why I said you can't use HiperSockets to connect LPARs in 
different zones:  No firewall.  Any time data transits to a different 
zone, it goes thru a firewall.  It is the firewalls that create the zones.

Note that "firewall" and "packet filter" are not the same.  A host may 
have a resident IPS/IDS solution, but it isn't a firewall.  Firewalls are 
stand-alone devices.
