other address object is named by combining the interface name with the suffix "
_net
" and this is
the network to which the interface belongs.
Tip: Creating address book folders
New folders can be created when needed and provide a convenient way to group
together related IP address objects. The folder name can be chosen to indicate the
folder's contents.
Now click the
Add
button at the top left of the list and choose the
IP4 Address
option to add a
new address to the folder.
Enter the details of the object into the properties fields for the
IP4 Address
object. Below, the IPv4
address
203.0.113.1
has been entered for the address object called
wan_gw
. This is the IP of the
ISP's router which acts as the gateway to the public Internet.
Click the
OK
button to save the values entered.
Then set up
G2_ip
to be
203.0.113.35
. This is the IPv4 address of the
G2
interface which will
connect to the ISP's gateway.
Lastly, set the
IP4 Address
object
G2_net
to be
203.0.113.0/24
. Both the address objects
G2_ip
and
wan_gw
must belong to the same network in order for the interface to communicate with the
ISP.
Together, these three IPv4 address objects will be used to configure the Ethernet interface
connected to the Internet which, in this example, is
G2
. Select
Network > Interfaces and VPN >
Ethernet
to display a list of the physical interfaces and address book objects assigned to them.
The first lines of the default interface list for the NetWall 6000 Series are shown below. Note that
this list includes
E1-1
to
E1-4
which correspond to Ethernet interfaces in the first expansion
module.
