Configuring Trusted Networking

The restricted and webservice zones are assigned a private IP address in addition to the IP address that they already share. Each private IP address has a multilevel port configured and is associated with a restricted label set.

The following table shows the network configuration for each of the labeled zones.

Zone Name
Zone Label
Local IP Address
Host Name
Multilevel Port
Security Label Set
restricted
CONFIDENTIAL : RESTRICTED
10.4.5.6
proxy
8080/tcp
PUBLIC
webservice
WEB GUARD SERVICE
10.1.2.3
webservice
80/tcp
CONFIDENTIAL : RESTRICTED
webcontent
WEB GUARD CONTENT
None

First, you must create the new zones. You can clone an existing zone, such as the public zone. After these zones are created, use the zonecfg command to add a network (with the address specified in the table) and your local interface name.

For example, the following command associates the 10.4.5.6 IP address and the bge0 interface with the restricted zone:

# zonecfg -z restricted
add net
set address=10.4.5.6
set physical=bge0
end
exit

After you specify the IP address and network interface for each labeled zone, use the txzonemgr script to configure the remaining values in the table. When you finish the configuration process, start or restart the affected zones. In the global zone, add routes for the new addresses, where shared-IP-addr is the shared IP address.

# route add proxy shared-IP-addr
# route add webservice shared-IP-addr
