Hi all,
I installed Firmware: DD-WRT v3.0-r47911 on a TP-Link Ac1750 v5 and I configured the vlan tagging as showed in the attachment but I am not able to use the router connected directly to the ONT.
Could you help me to understand how I can configure the vlan tagging to use the router as third party router?

You're trying to tag VLAN 0 on the networking page; I would have to see if that is a display error or correct, but I think you have to tag VLAN 2. As I found out, you have to add VLAN 1 and VLAN 2 and then tag the proper VLAN, most likely. @egc: I think that should be selectable on add instead of starting at 0 and requiring unnecessary adds the way it does. _________________ "Life is but a fleeting moment, a vapor that vanishes quickly; All is vanity"

It seems to me that something changed here, I don't recall it being this way before, and I am not about to dial up every router in the wild that requires this to check it. I could've sworn this defaulted to the WAN interface before or there was a selectable option of which vlan to tag. _________________ "Life is but a fleeting moment, a vapor that vanishes quickly; All is vanity"

Yes it is very confusing and a wiki would be perfect to better understand.
I'm honest, the DD-WRT build on this TP-Link is not very stable, sometimes it shows to me the "Switch" tab other time not.
Anyway I think that the correct way to set the VLAN tagging is in network. The real problem is that when I go on basic setup, sometimes a new sqare to flag saying "enable VLAN Tagging" compares but other time for example refreshing the page, I don't have the square to flag. It is very stressful.
I have also read on this https://wiki.dd-wrt.com/wiki/index.php/VLAN_Support:
Only Broadcom based devices support port-based VLAN's, no Atheros or Ralink devices. Non-Broadcom platforms support 802.1q VLAN tagging via the Networking page options (Linux's vconfig utility is used internally for this) but it often does not work correctly and it is for tagging entire interfaces (the LAN ports are all one interface on these platforms).
