NAT CLI Commands
--> nat add globalpool gp1 extinterface dmz
192.168.102.3 subnetmask 255.255.255.0
Example 2:
This example creates a network address pool that allows NAT to translate
packets between the external interface and the internal interface type.
First, NAT is enabled between the external interface and the DMZ interface
type:
--> nat enable n2 extinterface internal
Then the IP address and subnet mask is created:
--> nat add globalpool gp2 extinterface internal
192.168.103.2 endaddress 192.168.103.50
