Operating The TCP/IP module of the router may be activated or deactivated here. In the default
configuration, the TCP/IP module is activated.
Configuration via TCP/IP using Telnet and the IP router is possible only if the TCP/IP
module is activated.
Intranet- A second IP address for the router may be entered here. The second IP address enables
address
the device to be used as a router for two logical IP networks and also this address has a
specific meaning with the use of IP masquerading:
In this case, all computers that are in the network linked by Intranet address and Intranet
mask are hidden behind the address assigned by the provider (or the IP address).
Intranetmask
The network mask belonging to the IP address of the local network must be entered here.
The default setting is 255.255.255.0 (class C network).
If neither an IP nor an Intranet address has been specified, the device responds to a
default IP address, the first three digits of which are identical to the first three digits of
the sending device XXX.XXX.XXX.YYY. The device can then be reached by dialing the IP
address XXX.XXX.XXX.254.
In the event that such an address already exists in the network, a different address must
be entered via the keyboard (ELSA LANCOM Wireless IL-2 only) or via outband
configuration (terminal program).
If both an IP address and an Intranet address have been entered, the network defined by
an IP address and IP network mask must contain only workstations (i.e. no routers).
