DHCP Helper does not work with "-b wlan0"

[jean-christophe manciot]

In /etc/default/dhcp-helper, if DHCPHELPER_OPTS="-b eth0", everything works fine: my virtualized devices on tap interface get their IP configuration from a DHCP server located on "eth0".

If I change this setting to DHCPHELPER_OPTS="-b wlan0", it does NOT work anymore with the same environment; the DHCP DISCOVER are sent on the tap interface, but no answers are received from the DHCP server located on "wlan0".

If you need more information, I remain available.
