Wan IPV6 interface with 6rd protocol reports bad mac address
Username: Olivier Wuillemin
Origin: https://bugs.openwrt.org/index.php?do=details&task_id=2080
Device used is BT Home Hub 5 v1.2.
Openwrt release is 18.06.1,
6rd package version is 9-4
ISP
is Free (France)
“Wan” interface, IPV4, with Dchp client protocol is up and works fine on physical interface dsl0.836.
Mac address has to be overriden because
ISP
uses a fixed mac address, different for each Freebox, it’s own dsl modem/box.
“Wan6”, IPV6, interface with 6rd protocol is up but the mac reported in the not the same as those reported in “Wan” interface.
As you could see on the attached capture of the “Interfaces overview”, the mac address reported is the “Wan” IpV4 address !!!
Wan6 interface is up but frames are rejected by
ISP
because the mac address is not those one expected as for “Wan” interface. Mac address can’t be overriden on these interface.
network config is attached.
