4.4. DHCP_CLIENT - Dynamic Host Conﬁguration Protocol

With this package, the router sources IP addresses for its interfaces dynamically. The package

and its parameters are explained below.

4.4.1. OPT_DHCP_CLIENT

A DHCP client can be used to obtain an IP address for one or more interfaces of the router

- this is most used with cable modem connections or in Switzerland, the Netherlands and

France. Sometimes this conﬁguration is also needed if the router is behind another router,

that distributes the addresses via DHCP.

At the start of the router, for all speciﬁed interfaces IP addresses will be obtained. Subse-

quently, those are assigned to the interface and, if necessary, the default route on this interface

is set.

OPT_DHCP_CLIENT Has to be set to ’yes’, if one of the DHCP-clients is to be used.

Default Setting: OPT_DHCP_CLIENT=’no’

DHCP_CLIENT_TYPE At the moment, the package is equipped with two diﬀerent DHCP-

clients, dhclient and dhcpcd. You can choose which one is to be used.

Default Setting: DHCP_CLIENT_TYPE=’dhcpcd’

DHCP_CLIENT_N Here, the number of interfaces to be conﬁgured is neccesary.

DHCP_CLIENT_x_IF Here, the interface to be conﬁgured has to be speciﬁed as a reference to

IP_NET_x_DEV, i.e. DHCP_CLIENT_1_IF=’IP_NET_1_DEV’. The dhcp-client gets the apropriate

device out of this variable. In base.txt a placeholder ’dhcp’ should be entered instead of

an IP-address with netmask.

DHCP_CLIENT_x_ROUTE Here you can specify whether and how a route is to be set for

the interface. The variable can take the following values:

none No route for the interface.

default Default route for the interface.

imond Imond is used to manage the default route for the interface.
