Bridge Modes: Single Client
NAT Mode
Autodetect LAN client
: (Single
Client NAT only) If only one
LAN client is connected, it is
not necessary to define the
LAN client IP address when
activating this function.
LAN Client IP
: (Single Client
NAT only) All connection re
-
quests from the WLAN side
are forwarded to this IP speci
-
fied here.
Local IP address
: With this IP
address the radio modem
communicates on the LAN
side. LAN clients connected to
the HG G
76343/4/5 must
configure this IP as gateway
IP.
Subnet mask
: Subnet mask of
the local network.
Forward DNS requests
: This
option enables the forwarding
of DNS requests from the lo
-
cal network to the DNS server
of the WLAN page. This elimi
-
nates the need to configure a
special DNS server on the
LAN clients. In this case, only the local IP of the HG G
76343/4/5 must be entered.
MAC Authentication
: (NAT mode only) To prevent any device plugged into the LAN
port of the radio modem from connecting to the WLAN, it is now possible to register
the MAC address of the allowed devices. To do this, the permitted radio modem ad
-
dresses must be entered into the network's radius server. If you activate this option,
parameters are displayed that define access to the radius server:
1. IP address
2. port number
3. Shared secret
4. Timeout of the Auth.
For troubleshooting, this authentication function can be monitored more closely
with the
Radius Debug Level
parameter. With the setting
Detailed
or
Maximum
more
or less detailed messages are written into the log file, which indicate which steps of
the authentication were passed through.
