ASUS RT-AC87U
Firmware: DD-WRT v3.0-r47900 std (12/20/21)

Firsttime setup

On WAN port im sending in tagged VLAN2 & tagged VLAN3 (TV)
dd-wrt switchsetup is configured to accept these tagged VLANs on WAN and to untag VLAN3 on LAN port4 (Internet access works on LAN port 1-3)

However the device connected to LAN port 4 receives a DHCP lease from dd-wrt and the TV settop box I try to use is thus not workning.

I then desperatly tried to create a bridge where I add the vlan3. Tried with L2Mesh and to also thow in eth0 to the bridge but dhcp keeps being provided by dd-wrt. tried expermenting with unbridged and disable NAT - but nothing worked.

How shall I configure in GUI to get TV passthru with untagging to work?

I have a feeling that port numbering in web UI is not the same as the port numbering on the plastics

The link status shown in "Switch Config" does not match the cables connected. The LED diods match the cable connection tho...

The internal numbering in the switch is usually backwards compared to the one on the casing.
