# setup before hand:
# set "router" to "AP Mode"
# this will put all ports and wireless in br0
# create 2 guest network
# enable Administration => System => Enable JFFS custom scripts and configs
# put this script in /jffs/scripts/, name should be "services-start"
# remember `chmod a+x services-start`
# I strongly suggest you use static IP instead of DHCP
# In my test, the "router" will pickup DHCP lease from VLAN 1 instead of VLAN 227
# reboot
# some basic info of the original AP mode:
# eth0 => WAN port
# eth1~4 => LAN port 4~1, they're reversed
# eth5 => WiFi 2.4G
# eth6 => WiFi 5G
# wl0.1, wl0.2 => WiFi 2.4G guest networks

# WAN port (eth0) will be repurposed as a tagged port
# LAN ports (eth1~4) and primary WiFi (eth5,6) will be on VLAN 227
# guest network 1 will be on VLAN 11
# guest network 2 will be on VLAN 12

Here is example with variables, so it is easier to adopt to different models.

Ports (example RT-AX82U)

eth0 = LAN4
eth1 = LAN3
eth2 = LAN2
eth3 = LAN1
eth4 = WAN
eth5 = 2.4 GHz
eth6 = 5 GHz
wl0.1 = Guest 1 (2.4 GHz)
wl0.2 = Guest 2 (2.4 GHz)
wl1.3 = Guest 3 (5 GHz)

Tagged to WAN port (for example)

Default network = br0, vlan id 50
Guest network 1 = br1, vlan id 60
Guest network 2 = br2, vlan id 70
Guest network 3 = br3, vlan id 20

Script

script="/jffs/scripts/services-start"

So I have an AC86U and AX86S on the same network connected with a TPLink switch. I setup vlan ID 227 and 11 on the AC86U and then tagged ports 1-8 on the switch for 227 and untagged 11 on port 4. Do I need to also setup VLAN 227 on the AX86U and just not setup ID 11?

I have 1x AC86 (main AP) and 2x AC68 (nodes, wired backhaul).
Does AiMesh still work?
Do I have to enable this script on the three AP's or only one the main AP (AC86)?

I too have the same question. Does the script need to be run on each router (customised for each) or just on the main AP?
I have AX88U as the AP and AX56U as a AiMesh node.

Hello,
I have the same MESH Qs. How can I get this nice VLAN script to work within wired-connected ASUS MESH routers?

bump - I have a successful AP VLAN setup with AX88U and AX3000 not in mesh mode. I currently have simple Guest 1 as VLAN 10 and Guest 2 as VLAN 20. If I were to put APs in mesh mode with wired backhaul what would the default traffic look like? Also while I am writting does anyone have a location where I can find a list of NVRAM variables. I notieced I have a some that I am curious about i.e. wl_vif*; wl0.4_ifname, etc.

ASUS router with Asuswrt-Merlin in AP mode and VLAN configured in services-start.sh script can be connected directly to pfSense without managed switch and will work as configured?

For these purposes, it would be better to use something in openwrt, but yes, it will work that way.
