Can IP Filter be used with zones?
You have the same IP Filter functionality that you have in the global zone in an exclusive-IP zone. IP Filter is also configured the same way in exclusive-IP zones and the global zone. For shared-IP zones, the IPFilter features in Solaris 10 can be used to filter traffic passing between one non-global zone and other computers on the network. This includes the ability to use NAT features, i.e., redirect traffic destined for the global zone to non-global zones.
