FS#2080 - Wan IPV6 interface with 6rd protocol reports bad mac address

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.

I think this is a display bug in the ui. The 6rd-wan6 interface is a tunnel interface, it should not have an ethernet mac address at all. Please provide the output of `ifconfig` and `ubus call network.interface dump`

I attach the ifconfig and ubus output.

Ok for the ui bug.
My trouble seems an IPV6 behavoiur that I didn't explain yet.

Should the ui bug be reported to luci team ?

The UI bug should indeed be reported to the luci team.
The ubus output for the 6rd interface looks fine and in line with the specified network config
