Network address translation - NAT NAT command reference
iMG/RG Software Reference Manual (IPNetwork Functions)
4-142
Example Example 1
This example creates a network address pool that allows NAT to translate packets
between the external interface and the DMZ interface type.
First, NAT is enabled between the external interface and the DMZ interface type:
--> nat enable n1 extinterface dmz
Then the IP address and subnet mask is created:
--> 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 internal interface type:
--> nat enable n2 extinterface internal
Then the address range is created:
--> nat add globalpool gp2 extinterface internal 192.168.103.2 endaddress
192.168.103.50
