LANCOM L- 54ag Wireless – LANCOM L- 54g Wireless – LANCOM IAP- 54 Wireless
Default gateway – receives all packets that are not addressed to comput-
ers within the local network.
DNS server – translates network names (www.lancom.de) or names of
computers (www.lancom.de) to actual IP addresses.
The LANCOM 54 Wireless can perform the functions of both a default gateway
and a DNS server. In addition, as a DHCP server it can also automatically
assign valid IP addresses to all of the computers in the LAN.
The correct TCP/IP configuration of the PCs in the LAN depends on the method
used to assign IP addresses within the LAN:
IP address assignment via the LANCOM 54 Wireless (default)
In this operating mode the LANCOM 54 Wireless not only assigns IP
addresses to the PCs in the LAN, it also uses DHCP to specify its own IP
address as that of the default gateway and DNS server. The PCs must
therefore be configured so that they automatically obtain their own IP
address and the IP addresses of the standard gateway and DNS server (via
DHCP).
IP address assignment via a separate DHCP server
The workstation PCs must be configured so that they automatically obtain
their own IP address and the IP addresses of the standard gateway and
DNS server (via DHCP). The IP address of the LANCOM 54 Wireless must
be stored on the DHCP server so that the DHCP server transmits it to the
PCs in the LAN as the standard gateway. In addition, the DHCP server
should also specify the LANCOM 54 Wireless as a DNS server.
Manual IP address assignment
If the IP addresses in the network are assigned static ally, then for each PC
the IP address of the LANCOM 54 Wireless must be set in the TCP/IP con-
figuration as the standard gateway and as a DNS server.
For further information and help on the TCP/IP settings of your
LANCOM 54 Wireless, please see the reference manual. For more
information on the network configuration of the workstation comput-
ers, please refer to the documentation of your operating system.
