PLANET SG-1000 - Manual (Page 60)

Chapter 5
Address
The SG-1000 allows the Administrator to set Interface addresses of the LAN network,
LAN network group, WAN network, WAN network group, DMZ and DMZ group.
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 LAN IP address, WAN 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 LAN Group or the WAN
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 setup 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.
