Many thanks Jeppe. I am reconfiguring this zone to use ip-type=shared 
instead of exlusive. My zone config is:

zonename: dnssrvdmz
zonepath: /zones/dnssrvdmz
brand: ipkg
autoboot: false
ip-type: shared
	allowed-address not specified
	physical: e1000g1

But when I try to boot this new zone, console returns me this error:

"WARNING: skipping network interface 'e1000g1' which may not be 
present/plumbed in the global zone."

Do I need to "ifconfig up" this physical interface before zone boots??
