Setup/IP-router-module
This menu allows you to enter settings for the IP router module. The menu has the
following layout:
Operating This option allows you to activate or deactivate the IP router module. In the default
configuration, the IP router module is activated.
Activating the IP router module also activates the TCP/IP module.
IP-routing-table
The routing table can contain a maximum of 128 entries of destination network
addresses or direct IP addresses with netmasks, and the names or IP addresses of other
local routers. Alternatively, you can enter a setting by means of which packets to specific
destination IP addresses are discarded and are not answered by proxy ARP. This is done
by entering 0.0.0.0 for the name of the responsible router.
The 'Masquerade' field indicates whether the route should be masked or not. The
following options are offered here:
쮿
On : IP masquerading is switched on and functions with dynamic assignment of the
IP address by the remote station. In this procedure the router queries the IP address
'0.0.0.0' at the remote station and is assigned a random IP address by the remote
station, which is then used for further processing.
쮿
Off : Masquerading is switched off.
쮿
Static : IP masquerading is switched on and functions with assignment of a static
IP address previously assigned by the remote station. In this procedure the router
queries the IP address entered under 'Setup/TCP-IP-module' at the remote station
