Zyxel T-56 WAN Port Flapping Issue with VLAN Tagging

[psherman]

From what I understand, I need to add the tag ID (300) manually in order to get the internet to work. It wasn't working after installation without it either.

The point I was making is that the specific 802.1q stanza I quoted can be removed (unless that mtu setting is required).

That is because this stanza uses dotted notation (eth1.300):

@daniel4999

config interface 'wan'
        option device 'eth1.300'
        option proto 'dhcp'

When the dotted notation is used in OpenWrt, it automatically creates the 802.1q device under the hood... no 802.1q config stanza required.
