I’ve configured the ZTE 931Dll VDSL modem to be used with our standard DD-WRT router. This required modifying the ZTE settings to perform VLAN bridging for the DD-WRT router.
The general steps are outlined in another blog.
However, the critical last step is different. I tried the steps at the blog but it didn’t work. Using my head, I decided to try a different setting, which worked.
Set the LAN4 trunking to:
Enable VLAN trunk: Checked
Supported VLAN Number: 0
Then, configure the DD-WRT router to perform PPPoE as normal.
