LANCOM OAP-54 Wireless and LANCOM OAP-310agn Wireless
Chapter 3: Basic configuration
The LANCOM OAP Wireless can fulfill the functions of a standard gateway and
also of a DNS server. It can also operate as a DHCP server, which automatically
assigns IP addresses to all of the computers in the LAN.
The correct TCP/IP configuration of a PC in the LAN depends essentially on the
method used for assigning IP addresses in the LAN:


DNS server – translates network and computer names into their actual IP
addresses.
IP address allocation by a LANCOM
In this operating mode, a LANCOM uses DHCP to allocate not only an IP
address to each PC in the LAN and WLAN (for devices with a radio
module), but it also communicates its own IP address as the standard
gateway and DNS server. For this reason, the PCs have to be set up to
automatically retrieve their own IP address and those of the standard
gateway and DNS server via DHCP.
IP address allocation by a separate DHCP server
For this reason, the workstation PCs have to be set up to automatically
retrieve their own IP address and those of the standard gateway and DNS
server via DHCP. The DHCP server is to be programmed such that the IP
address of the LANCOM is communicated to the PCs in the LAN as the
standard gateway. The DHCP server should also communicate that the
LANCOM is the DNS server.
Manual IP address assignment
If IP addresses in a network are statically assigned, then the IP address of
the LANCOM is to be set as the standard gateway and DNS server in the
TCP/IP configuration of each PC in the LAN.
Further information and help on the TCP/IP settings for your LANCOM
OAP Wireless is available in the Reference Manual. For information on
the network configuration of workstation PCs, refer to the documen-
tation for the installed operating system.
