3. Base configuration
IP_NET_x_MAC Default Setting: IP_NET_1_MAC=”
Optional: MAC address of the network adapter.
With this variable you are able to change the hardware address (MAC) of your network
adapter. This is useful if you want to use a DHCP provider expecting a certain MAC
address. If you leave IP_NET_x_MAC empty or remove the variable definition completely,
the original MAC address of your network adapter will be used. Most users will never
need to use this variable.
Example:
IP_NET_1_MAC='01:81:42:C2:C3:10'
IP_NET_x_NAME Default Setting: IP_NET_x_NAME=”
Optional: Assigning a name to the IP address of a network adapter.
If you perform reverse DNS lookup of the network adapter’s IP address, the result is
typically a name like ’fli4l-ethx. domain ’. You can use the variable IP_NET_x_NAME in
order to change that name which will be returned when performing reverse DNS lookup.
If the IP address is globally accessible, you can use this setting to enforce that reverse
DNS lookups always return a globally accessible name.
Example:
IP_NET_2='80.126.238.229/32'
IP_NET_2_NAME='ajv.xs4all.nl'
IP_NET_x_TYPE
IP_NET_x_COMMENT Default Setting: IP_NET_x_COMMENT=”
Optional: You can use this setting to assign a ‘meaningful’ name to a network device.
This name can then be used in packages like rrdtool for identifying the network.
3.9. Additional routes (optional)
IP_ROUTE_N Number of additional network routes. Additional network routes are manda-
tory if e.g. other routers in the LAN exist which have to be used to access other networks.
Normally, you do not need to specify any other network routes.
Default setting: IP_ROUTE_N=’0’
IP_ROUTE_x The additional routes IP_ROUTE_1, IP_ROUTE_2, . . . are structured as follows:
