OpenWrt failed to configuring FTTH VLAN based PPPoE

[xiaobo]

My china provider requires that the traffic over the WAN interface is tagged with id 3961, and the rest can be untagged (I don´t have other services like IPTV or VoIp). Anyone could explain how i must configure ?

config interface 'wan'
	option ifname 'eth1.3961'
	option proto 'pppoe'

and you probably want to make port 10 tagged too.

Both tagged.
