I am finally after 20 years getting gigabit fiber in my house. My ISP allows me to use my own router, so I don't need their router/modem but it requires that I set up my own router to use VLAN tagging on 101. My router is a Buffalo WZR-D1800H running DD-WRT v3.0-r45563 giga (01/24/21). It has a Broadcom BCM5300 chip rev 1. I am a noob regarding how to do vlan tagging. I tried to look various forum posts but I am having issues running this command "swconfig" because I get this error:

sh: eval: line 1: swconfig: not found

do I need to enable something in DD-WRT first? Is there a to vlan tag via the GUI or is it only possible via command-line and scripts?

VLAN tagging is more or less platform dependent (in the past more, now less)

for Broadcom things changed a lot, update to the latest build 47117 as of today (research if that is suitable for your router, see forum guidelines)

To get the best out of DDWRT and the forum read the forum guidelines with helpful pointers:

I will transfer your post to the Broadcom forum

OK, I just updated my firmware to the latest dd-wrt. Here is a screenshot of the VLAN section in webgui. My ISP writes in their documentation on how to set up vlan tagging, that they send traffic out on VLAN 101 so the VLAN on my router needs to be tagged to 101 and the IP should be set to DHCP. I am a bit unsure on what to change here. Any advice would appreciated!

I am not a VLAN expert, I knew my way around the old Broadcom nvram method but this is new and shiny (and a WIP).

It could be as easy as just replacing the 2 (which is your WAN) with 101 and probably enable tagging but as said I am not the expert.

Trying to do this I discovered that the VLAN id input box only allowed two digits so it stops at 99 Sad

While I think that we should be able to go as high as 4096.

I patched it and send it upstream and the Big-kahuna already accepted and committed it Smile
https://svn.dd-wrt.com/changeset/47134

But to try this you have to wait till the next build.

In the mean time I hope some of our VLAN gurus will chime in.

That's not the latest DD-WRT. You have 15 vlans on that page, when you should only have 0, 1, and 2.

That's odd. I am running this build on my R6250 and I have 15 vlans on that page. Just the differences in the routers perhaps?

Maybe a leftover from earlier which will be gone after reset to defaults?

That's certainly a possibility.

I didn't have to do any resets, all I had to do was navigate to the page from the main setup page. Perhaps a CTRL+F5 or clearing of browser cache or even a reload of the page.

It is the latest DD-WRT. I just updated it today but I didn't do reset though.
