Appendix II – Wireless with Router Mode
This section provides more details on wireless with router function.
The role of the LAN and WLAN interface will change accordingly to the Wireless Mode while
the device is operating in Router mode:
• Wireless interface and all the wireless clients connected are considered as the internal
LAN and the Ethernet interface is dedicated for the connection to the external network
while the device is operating in AP/AP WDS wireless mode;
• Wireless interface and all the wireless clients connected is considered as the external
network and the all the network devices on LAN side as well as the Ethernet interface
itself is considered as the internal network while the device is operating in Station/Station
WDS mode.
Wireless/wired clients are routed from the internal network to the external one by default.
Network Address Translation (NAT) functionality works the same way.
AP-Router mode Network Settings
IP Address : This IP addresses represents the LAN or WLAN interface which is connected to the
internal network according to the wireless operation mode described above. IP will be used for
routing in internal network (it will be the Gateway IP for all the devices connected on the internal
network). IP address also will be used for the management purpose of the device.
WLAN IP Address: This IP addresses represents the LAN or WLAN interface which is connected
to the external network according to the wireless operation mode described above. This is the IP
address can be used for the routing and the device management purposes. The external network
interface can be set for static IP or can be set to obtain an IP address from the DHCP server which
should reside in the external network. One of the IP assignment modes must be selected for the
external network interface:
DHCP – choose this option to obtain the IP address, Gateway and DNS address
dynamically from the external DHCP server.
PPPoE – choose this option to obtain the IP address, Gateway and DNS address dynamically
from the external PPPoE server.
Static – choose this option to assign the static IP settings for the external interface.
IP Address and Netmask settings should consist with the address space of the network
segment where the device resides. If the device IP settings and administrator PC
(which is connected to the device through wired or wireless) IP settings will use
different address space, the device will become unreachable.
Netmask: This is used to define the device IP classification for the chosen IP address range.
255.255.255.0 is a typical netmask value for Class C networks, which support IP address range
192.0.0.x to 223.255.255.x. Class C network Netmask uses 24 bits to identify the network
(alternative notation "/24") and 8 bits to identity the host.
