Chapter 3: Basic configuration

EN
Server: The LANCOM VPN Router operates as DHCP server in the net-
work; as a minimum its own IP address and the network mask must
be assigned.
Client: The LANCOM VPN Router obtains its address information from
another DHCP server; no address information is required.
IP address and network mask for the LANCOM VPN Router
Assign the LANCOM VPN Router a free IP address from your LAN's address
range and enter the network mask.
Gateway address
Enter the gateway's IP address if you have selected 'Off' as the DHCP
mode of operation or if another network device is assuming the role of
gateway in the 'Server' mode of operation.
DNS server
Enter the IP address of a DNS server to resolve domain names if you have
selected 'Off' as the DHCP mode of operation or if another network device
is assuming the role of DNS server in the 'Server' mode of operation.
3.1.2 Configuration protection
Using a password secures access to the LANCOM VPN Router's configuration
and thus prevents unauthorized modification. The device's configuration con-
tains a great deal of sensitive data such as data for Internet access and should
be protected by a password in all cases.

Multiple administrators can be set up in the configuration of the
LANCOM, each with differing access rights. Up to 16 different admin-
istrators can be set up for a LANCOM VPN Router. Further information
can be found in the LCOS reference manual under “Managing rights
for different administrators”.
3.1.3 Settings for the DSL connection
It may be necessary to enter the transmission protocol used for the DSL con-
nection. The wizard will enter the correct setting for the most important DSL
providers on its own. Only when the wizard does not list your provider must
the transmission protocol used by your DSL provider be entered.
The wizard will offer you a universal 'multimode' protocol that works with all
common types of DSL connection.
