# multi SSID with VLAN script, for ASUS AC86U with merlin
#
# 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
# this setup:
#       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

@robertr1229 tell more about your setup. Especially what you mean by trunk port? pfSense do not have trunk ports (I have heard some rack Netgate models have, but I doubt that you have one) nor Asus. You have Cisco switch with DTP/VTP? Maybe just tell which networks you have VLAN tagged/untagged and which ports.

I think the issue is not setting a static IP before running the script. As for Trunk ports. That is not a physical port. A Trunk port is used to transmit multiple tagged VLANS on a single port or "VLAN Aware" Asus Merlin may not be able to support it but PFSense definitely can. As well as any managed switch.

I also just saw your config for the RT-AX82U. I am using the same device and will give it a try. I would like to have Trunking but I can live with just setting it up on a Native VLAN.

Yes, I know what trunk ports are used for. pfSense definately supports tagging VLANs on single physical port, but if we are really talking about 802.1Q trunking it (DTP/VTP) is Cisco proprietary protocol. Other place where trunking word is sometimes used is link aggregation ("port trunking").

This thread was all very helpful in figuring this out.
I'm on an AX-58U. For some reason, all the wifi connections (guest networks and eth5-6) work without issue. Even though I have eth0-3 configured the exact same way and on the same vlan, they are only able to reach the AX-58U and other devices connected directly to it. Wifi devices can ping the gateway, reach the internet and opnnsense settings no problem.
I've been trying things for a couple days now. I'd love any help. Thanks in advance

Thanks @Jimmy-Z @Knud3 @demarey-baker !

I went with something a little different to also handle wireless restarts.

I run my RT-AX88U router in Access Point mode, with an OPNsense box upstream. Wanted to segregate the wireless networks into their own vlans.

The restart_wireless Issue

Initially, any restart_wireless event was:

• Reassigning all wireless interfaces back to br0

  # $ brctl show
  
  bridge name	bridge id		STP enabled	interfaces
  br0		8000.a036bcb34a28	no		eth0.10
  							eth5
  							eth6
  							eth7
  							wl0.1
  							wl0.2
  							wl0.3
  							wl1.1
  							wl1.2
  							wl1.3
  br1		8000.a036bcb34a28	no		eth0.20
  br2		8000.a036bcb34a28	no		eth0.30
  							eth4
  br3		8000.a036bcb34a28	no		eth0.40
  							eth3
  br4		8000.a036bcb34a28	no		eth0.50
  br5		8000.a036bcb34a28	no		eth0.60
  							eth1
  							eth2
  

• Resetting nvram for the following, to:
  • lan_ifnames=eth0 eth1 eth2 eth3 eth4 eth5 eth6 eth7 wl0.1 wl0.2 wl0.3 wl1.1 wl1.2 wl1.3
  • br0_ifnames=eth0 eth1 eth2 eth3 eth4 eth5 eth6 eth7 wl0.1 wl0.2 wl0.3 wl1.1 wl1.2 wl1.3

So intercepting it from the service-event-end script and reassigning wireless interfaces back to their original bridges fixed it. No more need to reboot after modifying something now.

Hope it helps!

This thread was all very helpful in figuring this out. I'm on an AX-58U. For some reason, all the wifi connections (guest networks and eth5-6) work without issue. Even though I have eth0-3 configured the exact same way and on the same vlan, they are only able to reach the AX-58U and other devices connected directly to it. Wifi devices can ping the gateway, reach the internet and opnnsense settings no problem. I've been trying things for a couple days now. I'd love any help. Thanks in advance

Eth4 is physically LAN or WAN?

I run my RT-AX88U router in Access Point mode, with an OPNsense box upstream. Wanted to segregate the wireless networks into their own vlans.

@05nelsonm
Could you please help me with a modified script? 🙏🏼
My setup is the same as yours... Internet -> OPNsense -> RTAX88U

I am looking for the following VLAN tagging on my AX88U, running latest Merlin software.

#
# VLAN10 (Tag - 10) [ LAN ]
#	br0	eth4		Physical ports 1
#		eth3		Physical ports 2
#		eth2		Physical ports 3
#		eth1		Physical ports 4
#		eth5		Physical ports 5-8
#		eth6		2.4GHz LAN
#		eth7		5.0GHz LAN
#
# VLAN60 (Tag - 60) [ Guest ]
#	br1	wl0.2		2.4GHz guest2
#
# All other guest wifi radios disabled

Requests:

1. Could you please help out with the scripts that work for my setup?

2. I am also running an additional AX56U (which acts as a Mesh node to the master AX88U). Would I need to change anything in the AX56U or would it just keep acting as a mesh node and use the same VLANs automatically?

Has anyone else had an issue attaching the
Asus AP LAN ports to the VLANS ?
Clients on wl interfaces come up with the correct VLAN subnet. However anything connected to the LAN ports cannot get an IP address no matter which VLAN I configure the port under. I am using an ax58 connected to a tp link managed switch.

Everything else works. Including GUI access but non of the LAN ports come up.
Any insight is appreciated

Did you ever figure out why lan ports are not running? I have the same issue

Are you sure the VLAN is configured correctly in the Netgear Switch? I have that same switch and it took me a while to understand how the VLAN works. If I didn't have another switch lying around I would have thought it was something else. Tell me how you configured the VLAN on the Netgear switch. For this to work you need to pass through all of the VLANs to the ASUS router and then it will then route it out correctly.

How did you manage to connect your ASUS AP to the PFsense box/via switch? I'm trying the same, I just want to VLAN my Guest Networks from ASUS AP. I've setup normal VLANS correctly with DHCP in OPNSense, and in Netgear GS308T Managed Switch I have connected my ASUS Router/AP to PORT 5. I've tagged Port 5 with VLAN 50 (only 1 vlan), but I can never achieve connectivity. Which port are you actually using from the ASUS to hookup to your switch? I've used the WAN port (eth0) to hookup to switch. It does not work for me. — Reply to this email directly, view it on GitHub <https://gist.github.com/6120988090b9696c420385e7e42c64c4#gistcomment-4461199> or unsubscribe <https://github.com/notifications/unsubscribe-auth/AHWKBERLAKTBEYYXC33BUXTWWCU2XBFKMF2HI4TJMJ2XIZLTSKBKK5TBNR2WLJDHNFZXJJDOMFWWLK3UNBZGKYLEL52HS4DFQKSXMYLMOVS2I5DSOVS2I3TBNVS3W5DIOJSWCZC7OBQXE5DJMNUXAYLOORPWCY3UNF3GS5DZVRZXKYTKMVRXIX3UPFYGLK2HNFZXIQ3PNVWWK3TUUZ2G64DJMNZZDAVEOR4XAZNEM5UXG5FFOZQWY5LFVA4TIOJQGAYTGOFHORZGSZ3HMVZKMY3SMVQXIZI> .

Did you ever figure out why lan ports are not running? I have the same issue

In AC86U, if using another interface for trunk port (instead eth0), then you need to apply this command:

ethswctl -c hw-switching -o disable

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

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.
