࡯ DNS server – translates network names (www.lancom.de) or names of
computers (www.lancom.de) to actual IP addresses.
The LANCOM Router 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 Router (default)
In this operating mode the LANCOM Router 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 Router 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 Router 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 Router must be set in the TCP/IP configu-
ration as the standard gateway and as a DNS server.
 For further information and help on the TCP/IP settings of your
LANCOM Router, please see the reference manual. For more informa-
tion on the network configuration of the workstation computers,
please refer to the documentation of your operating system.
