When defining a network, the first setting is for the IP address range which is to be valid for a certain local interface on the router. "Local interfaces" are logical interfaces which are assigned either to a physical Ethernet port (LAN) or to a wireless port (WLAN). To realize the scenarios outlined above, it is possible for several networks to be active on one interface: Conversely, a network can also be active on multiple interfaces (via bridge groups or with the interface assignment 'Any').
The networks are defined in a table under
. A unique name for the networks is set along with definitions for the address range and interface assignment. The network name allows the identification of networks in other modules (DHCP server, RIP, NetBIOS, etc.) and to enable control over which services are available in which networks.![](pictures/config_tcpip_general_ipnetworks.png)
