sends all other data packets into the cable network (insofar as these are not in forbidden areas):

	Enable local routing for this function.
Loc. routing	Local routing enables the router to forward data packets via the local network. The local
	routing is necessary if the router, as the default gateway for the workstations receives
	packets for destination networks to which it cannot establish a connection itself. If the

router cannot return the address of the appropriate router to the workstation via IMCP, it will forward the data to the corresponding router itself (see also 'Local Routing'). Since this setting increases network utilization in the LAN, the default setting is 'Off'.

Setup/IP-router-module/Routing-method

The router offers two methods for IP routing, which can be separately set for IP and ICMP packets. Both methods are based on the evaluation of the field 'Type-of-service' in the IP header.

The menu has the following layout:

/Routing-method	Routing method settings
Routing-method	Routing method for IP packets
ICMP-routing-method	Routing method for ICMP packets

Routing-method

ICMP-routing- method

This option allows you to define the routing method used for IP packets:

KIf you select 'Normal', all IP packets are handled in the same way as per the routing specifications of the Internet protocol.

KIf you select 'Type-of-service', IP packets are placed in the urgent queue or reliable queue, depending on the contents of the 'Type-of-service' field. All other packets are placed in the normal send queue. In this way, transmission is guaranteed, provided that it is possible.

This option allows you to define the routing method used for ICMP packets:

KIf you select 'Normal', the ICMP packets are handled like any other IP packets as per the routing specifications of the Internet protocol.

KIf you select 'Reliable', all ICMP packets received are placed in the reliable queue.
