Address
The DFL-80 Firewall allows the Administrator to set Interface addresses of the
Internal network, Internal network group, External network, External network
group, DMZ and DMZ group.
What is the Address Table?
An IP address in the Address Table can be an address of a computer or a sub
network. The Administrator can assign an easily recognized name to an IP
address. Based on the network it belongs to, an IP address can be an internal
IP address, external IP address or DMZ IP address. If the Administrator needs
to create a control policy for packets of different IP addresses, he can first add
a new group in the
Internal Network Group
or the
External Network Group
and assign those IP addresses into the newly created group.
Using group
addresses can greatly simplify the process of building control policies.
With easily recognized names of IP addresses and names of address groups
shown in the address table, the Administrator can use these names as the
source address or destination address of control policies. The address table
should be built before creating control policies, so that the Administrator can
pick the names of correct IP addresses from the address table when setting up
control policies.
