Scan LAN Clients : If LAN clients
are passive on the HG G - 76343/
4/5, i.e. do not send data via
Ethernet themselves without a
request, this function can be
used to cause the HG G
- 76343/
4/5 to regularly scan the net -
work on the LAN side via ARP re -
quest. As a result, the
HG G
- 76343/4/5 can quickly
registered all connected LAN cli -
ents, especially after a restart.
Forward Multicast / Broadcast :
This option determines whether
broadcast data arriving at the
HG G
- 76343/4/5 via WLAN is
forwarded to the LAN side.
Enable DHCP Relay Agent : If the LAN clients on the radio modem obtain their IP ad -
dress via DHCP, this option can support this by the HG G - 76343/4/5 manipulating
the DHCP requests of the LAN client so that the responses arrive correctly at the
LAN clients. The need for support depends on the network structure on the WLAN
side and the properties of the DHCP server.
Enable passive client helper : If a device is connected to the LAN port that does not
communicate via the LAN port on its own but only responds to requests, this func -
tion can be used to make the LAN client with its IP better known as a station in the
WLAN. As soon as the client is recognized by an ARP request, the radio modem
sends a ping request in the name of the LAN client to a specified IP address. This
happens only approx. 1x per minute and only if there is no other communication.
Helper IP : An IP to which the ping request is sent can be defined here. If the param -
eter is 0.0.0.0, the gateway IP is used as the destination.
