Setup/TCP-IP module

This menu allows you to enter settings for the TCP/IP module. The menu has the
following layout:

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.

IP address

The IP address for the router may be entered here. The default address on delivery is
'0.0.0.0'.

If IP masquerading is used, this address takes on a special meaning in connection with
the Intranet address:

If the IP address is assigned to the router by the Internet provider by PPP, all computers
in the network linked by IP address and IP network mask are normally routed. These
computers can then also be accessed directly from the Internet.

IP-netmask

The network mask belonging to the IP address must be entered here. The default setting
is 255.255.255.0 (class C network). A network mask of 255.255.255.255 means that there
is only one computer in this network (the router itself). This setting (an IP address
registered in the Internet with a fully assigned network mask) can be used for

/TCP-IP-module

TCP/IP module settings

State

Activates or deactivates the TCP/IP module.

IP-address

Local IP address

IP-netmask

Local network’s matching IP network mask

Intranet addr.

Local Intranet address

Intranetmask

Local network’s matching Intranet network mask

Access-list

Restricts access to internal functions via TCP/IP.

DNS-default

Domain name server

DNS-backup

Backup domain name server

NBNS-default

NetBIOS name server

NBNS-backup

Backup NetBIOS name server

Table-ARP

ARP-aging-min.

Dwell time for entries in the ARP table

TCP-aging-min.

Time limit for configuration connections that are inactive

TCP-max.-conn.

Max. number of simultaneous configuration connections to the
