Cable IP address

IP netmask

Configuration via TCP/IP using Telnet and the IP router can only be used if the TCP/IP module is activated.

The IP address for the device as transmitted by the headend during the registration is displayed here. The default address on delivery is '0.0.0.0'.

This IP address is used by the cable modem for the connection to the provider's (cable network operator) network.

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 masquerading via a raw IP access. With such an access an IP address is not assigned to the router by a PPP negotiation, but it must have a fixed IP address registered in the Internet.

Cable-IP- netmask

LAN-IP- address

LAN-IP-netmask

The netmask associated with the IP address as transmitted by the headend during the registration is displayed here.

The LAN-side IP address for the device can be entered here. The second IP address enables 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 the LAN-side IP address and IP netmask are “hidden” behind the address assigned by the provider (or the cable IP address).

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 no LAN-IP address has yet 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.
