Vlan tagging in B1300 in the WAN port

likaroti · 2020-06-04T11:13:31.859Z

Hi! I just bought a gl b1300 router. I’m using stock openwrt.

My home internet configuration requires vlan tagging on the wan port in order to be able to connect to my isp. However, there is no vlan option for the wan port, only for the two lan ports (and cpu).

Why is this happening, and is there a way to do achieve what I want? I’m quite preocupied as I bought the router thinking everything would work out and now I’m not able to get vlans in that port .

I have no problem in doing this in the command line, if this is just a problem with the web interface.

Thanks!

it is available in Luci under more settings > Advanced.

Network > Switch

sorry, can’t seem to find “more settings > addvanced”. ( @reflector it seems you were talking about the glinet interface, but I’m already using stock openwrt, so I only have luci )

when I go to “Network > Switch” (http://192.168.1.1/cgi-bin/luci/admin/network/switch)

I see only

000sw1960×624 40.1 KB

which doesn’t include vlans for wan.

no help whatsoever? I’m really lost, every tutorial I see on the web allows for tagging the WAN port, I don’t see why my router doesn’t

my 750s has it. try tagging it on the CPU?

that doesn’t seem to work…

I found this IPQ40xx Switch Config "Strangeness" - For Developers - OpenWrt Forum, which is somewhat similar. But still, doesn’t seem to help.

If it’s some driver issue, this means that the hardware is incapable, or that the driver was written without supporting this option?

After burning a lot of time on this issue, I found out that with the stock firmware, vlans will probably work, as long as you don’t use id=1 or id=2.

Unfortunately my ISP requires vlan id=2.

From what I can tell, this limitation is partly due to the qualcomm chip, but mostly due to a poorly thought out linux driver.

So I flashed OpenWRT (snapshot version), where a workaround is possible. For instructions, see my post to the OpenWRT forum thread here: IPQ40xx Switch Config "Strangeness" - #66 by rvl - For Developers - OpenWrt Forum
