Description of the menu options
ELSA LANCOM DSL/10 Office
R33
Each of the maximum of 16 entries in the access list has the following structure:
Once an IP workstation with its IP address and the network mask 255.255.255.255 is
entered into the list, the internal functions of the router can only be accessed from this
computer. Any requests from devices with different IP addresses are ignored.
If a complete network has access enabled to an
ELSA LANCOM
, this can be done as
follows for a class C network:
With this entry all IP addresses in the class C network 192.234.222.0 are authorized to
use internal functions of the router.
DNS-default
The entry
DNS
(Domain Name Server) is required to announce the name server
responsible for their own network for computers that have direct access via PPP to the
router.
If the router is configured for access to the Internet via an Internet Service Provider, the
DNS server is usually given by the provider. There are then two possible settings in the
router:
K
'0.0.0.0' is entered as the address of the DNS server. All computers in the local
network can then use the provider's DNS server.
K
The router's own IP address is entered as the DNS server. Then he uses the
DNS information from the provider not only for its own local network but also
forwards this information (DNS forwarding). Remote stations such as computers
that dial in via remote access can then also access the provider's DNS server. This
proced ure is also referred to as DNS forwarding.
DNS-backup
With the entry
DNS-Backup
a second name server can be named, which is used if the
DNS fails.
NBNS-default
The entry
NBNS-default
(NetBIOS Name Server) is required to announce the NBNS
responsible for their own network for computers that have direct access via PPP to the
router.
NBNS-backup
With the entry
NBNS-Backup
a second name server can be named, which is used if the
NBNS fails.
IP-address
IP netmask
IP address of the authorized user (or user
circle)
IP network mask of the user circle
IP-address
