D Default: 0.0.0.0
The IP address from the global TCP/IP settings is communicated as
the backup NBNS server.
U Forwarding DHCP requests
D Server address
This is where the IP address for the superordinate DHCP server is
entered when the mode 'Relay requests' is selected.
D Caching of server responses
This option allows the responses from the superordinate DHCP server to
be stored in the BAT Router. Subsequent requests can then be answered
by the BAT Router itself.
This option is useful if the superordinate DHCP server can only be
reached via a connection which incurs costs.
D Adaption of server responses to the local network
This option allows the responses from the superordinate DHCP server to
be adapted to the local network. When activated, the BAT Router adapts
the responses from the superordinate DHCP server by replacing the fol-
lowing entries with its own address (or local configured addresses):
D Gateway
D Netmask
D Broadcast address
D DNS server
D NBNS server
D Server ID
This option is worthwhile if the superordinate DHCP server does not per-
mit the separate configuration for DHCP clients in another network.
U Multiple networks at one interface
With the configuration of IP and DHCP networks, multiple networks with dif-
ferent DHCP settings can be active at a logical interface. In this case, the
DHCP settings for the first suitable network are applied. A prioritization of net-
works may be necessary here.
