ebtables.post in the directory conﬁg/ebtables. Ebtables.pre will get executed before and ebta-

bles.post after conﬁguring the netﬁlter. Please remember that an error in the ebtables scripts

may interrupt the boot process of the ﬂi4l-router!

Before using EBTables you should deﬁnitely read the complete documentation.

By using EBTables the complete behavior of the router may change! Especially

ﬁltering by mac: in PF_FORWARD will not work as before.

Have a look at this page giving a small glimpse about how the the ebtables support works:

4.2.8. ETHTOOL - Settings for Ethernet Network Adapters

By setting OPT_ETHTOOL=’yes’ the ethtool program will be copied to the ﬂi4l router in order to

be used by other packages. By the help of this program, various settings of Ethernet network

cards and drivers can be displayed and changed.

ETHTOOL_DEV_N Specify the number of settings to set at boot time.

Default: ETHTOOL_DEV_N=’0’

ETHTOOL_DEV_x ETHTOOL_DEV_x indicates for which network device the settings should

apply.

Example: ETHTOOL_DEV_1=’eth0’

ETHTOOL_DEV_x_OPTION_N ETHTOOL_DEV_x_OPTION_N indicates the number of settings

for the device.

ETHTOOL_DEV_x_OPTION_x_NAME

ETHTOOL_DEV_x_OPTION_x_VALUE The variable ETHTOOL_DEV_x_OPTION_x_NAME gives

the name and ETHTOOL_DEV_x_OPTION_x_VALUE the value of the setting to be changed.

Following is a list of options and possible values activated by now:

• speed 10|100|1000|2500|10000 expandable by HD or FD (default FD = full duplex)

• autoneg on|oﬀ

• advertise %x
