TCP/IP settings to workstation PCs
The correct addressing of all devices within a LAN is extremely important for
TCP/IP networks. In addition, all computers must know the IP addresses of two
central points in the LAN:
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 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).
