values entered are propagated as follows:
– All networks which can be reached while a connection is established to a
destination network are propagated with a distance of 1.
– All non-connected networks are propagated with the distance entered in the
routing table (but with a minimum distance of 2) as long as a free transmitting
channel is still available.
– The remaining networks are propagated with a distance of 16 (= unreachable) if
there are no longer any channels available.
– Remote stations connected using Proxy ARP are an exception to this. These
”Proxy hosts“ are not propagated at all.

Mask.
Use the 'Masquerade' option in the routing table to inform the router which IP
addresses to use when transferring the packets.
– 'Off': No masquerading.
– 'On': This entry requests a random IP address valid in the Internet from your
provider which is then used for the connection and masquerading.
– 'stat.': Use this entry to request the assignment of a specific IP address from your
provider as entered in the 'TCP/IP' configuration section on the 'General' tab or
in the
/Setup/TCP-IP-module
menu. This address will be used for the
connection and masquerading.
For further information see the 'IP Masquerading' section.

Following entries have a special meaning:
– IP address 255.255.255.255 with a network mask of 0.0.0.0: This is the default
route. Any data packets which cannot be routed by other routing entries are
transmitted to the remote station listed here.
– Network mask 255.255.255.255: Entries with completed network masks
frequently only identify individual workstation computers (remote access) and
not actual networks. A network which is only visible by a single IP address using
IP masquerading may sometimes be concealed behind this.
– Router name 0.0.0.0: Exclusion routes. Data packets for this ”zero route“ are
rejected and are not routed any further. This is how routes which are forbidden
on the Internet (private address spaces, e.g. 10.0.0.0), for example, are excluded
from transmission.
Examples with explanatory notes:
IP address Netmask Router Dist. This is what happens:
192.168.1.9 255.255.255.255 FIELD SERVICE 2 The FIELD SERVICE remote station
can be reached at IP address
192.168.1.9.
