5.4.7 Administration
On this page, the access protection for the web interface is set with a user name and
password. The default settings for user name and password are both empty, i.e. there is
no user name and no password.
In addition, this page offers the opportunity, to restart the INSYS WLAN bridge or to
restore the factory defaults.
5.4.8 Bridging Function “Layer 2.5 NAT”
The bridging function “Layer 2.5 NAT”, which is built into this INSYS WLAN bridge,
enables safe and convenient bridging between two network segments.
The bridging function works transparently for IP connections and requires no special
network settings for the individual devices. All devices must simply be located in the
same network segment, like for a direct cable connection. A gateway setting is not
required either.
The INSYS WLAN bridge itself must be allocated its own IP address from the available
local address area. This IP address is basically required for the configuration.
Regarding network technology the bridging function works on MAC level. To reach a
device that is connected to a network, an ARP request is sent, which inquires at which
MAC address the required device is located. The INSYS WLAN bridge forwards these ARP
requests to all connected devices (wireless or not). When the ARP request has arrived on
one side of the INSYS WLAN bridge (e.g. on the WLAN side), and a device on the other
side of the INSYS WLAN bridge (e.g. LAN interface) replies, the INSYS WLAN bridge sends
