4. Packages

IP4 – IP address (ipv4) of the n’th host

IP6 – IP address (ipv6) of the n’th host (optional). If you use “auto”, then the address

will be computed automatically – either the address ::ffff:<IPv4> will be used,

or (if you activate OPT_IPV6) a “proper” IPv6 address will be set, consisting of

an IPv6 preﬁx (with /64 subnet mask) and the MAC address of the corresponding

host. In order to make this work, you will have to set HOST_x_MAC (see below) and

to properly conﬁgure the “ipv6” package.

DOMAIN – DNS domain of the n’th host (optional)

ALIAS_N – Number of aliasnames of the n’th host

ALIAS_m – m’th aliasname of the n’th host

MAC – MAC address of the n’th host

DHCPTYP – Assigning the IP address by DHCP depending on MAC or NAME (op-

tional)

In the sample conﬁguration ﬁle 4 hosts are conﬁgured, “client1”, “client2”, “client3” and

“client4”.

HOST_1_NAME='client1' # 1st host: ip and name

HOST_1_IP4='192.168.6.1'

Alias names must be speciﬁed with complete domain.

The MAC address is optional and is only relevant if ﬂi4l is used as a DHCP server

additionally. This is explained below in the description of the optional package “OPT_-

DHCP” Without use as a DHCP Server only the IP address, the name of the host and

possibly the alias name are used. The MAC address is a 48-bit address and consists of 6

hex values seperated by a colon, for example

HOST_2_MAC='de:ad:af:fe:07:19'

Note: If ﬂi4l is supplemented with the IPv6 packet, IPv6 addresses are not needed, if

the MAC addresses of the hosts are present, because the IPv6 packet calculates the IPv6

addresses automatically (modiﬁed EUI-64). Of course, you can disable the automatic

and use dedicated IPv6 addresses, if you wish.

Extra Hosts

HOST_EXTRA_N HOST_EXTRA_x_NAME HOST_EXTRA_x_IP4 HOST_EXTRA_x_IP6

Using these variables, you may add other hosts which are not members of the local do-

main e.g. hosts on the other side of a VPN.

4.5.2. DNS-Server

OPT_DNS To activate the DNS-server the variable OPT_DNS must be set to ‘yes‘.

If in the LAN no Windows machines are used or it has already a running DNS server,

OPT_DNS can be set to ‘no’ and you may skip the rest in this section.

In doubt, set (Default setting): OPT_DNS=’yes’
