@grifo It hasn't worked out.

I had hoped I could just change the virtual NIC driver and do one change in the real NIC, like it is described here, but had no success. Now I probably have to install the realtek vlan software to get this going, although it might not support having no vlan...

Yeah Realtek NICs have a reputation of not so great VLAN support.

By the way, just the robocfg line should in fact be enough for this to work, you can try it after you've sorted your PC's NIC.
Code: 
robocfg vlan 199 ports "0t 4t"
 
Managed to get it working with some help.
I had to install Hyper-V to later use their vswitch with VMware Workstation... sounds crazy, right?
With an intel NIC I would be able to use their vlan virtual NICs instead of going with hyper-v ones. With realteks own solution, I couldn't get it to work with VMware Workstation.

Dear @grifo,
I would like to create a second guestnetwork with vlan id 202. Do I have to create a second bridge (br2) like so?
Code: 
#!/bin/sh
robocfg vlan 199 ports "0t 4t"
robocfg vlan 201 ports "4t 5t"
robocfg vlan 202 ports "4t 5t"
vconfig add eth0 201
vconfig add eth0 202
ifconfig vlan201 up
ifconfig vlan202 up

brctl addbr br1
brctl delif br0 wl0.1
brctl addif br1 vlan201
brctl addif br1 wl0.1
ifconfig br1 up

brctl addbr br2
brctl delif br0 wl0.2
brctl addif br2 vlan202
brctl addif br2 wl0.2
ifconfig br2 up

It is working. Something to optimize?

Yeah it looks ok, just the nvram set lan1_ifname should be nvram set lan2_ifname for the second bridge interfaces.
Code: 
nvram set lan2_ifnames="vlan202 wl0.2"
nvram set lan2_ifname="br2"
 
@grifo, thanks, this also works. :)
Interesting that it seems to work anyway.

Dear @grifo, I wanted to consolidate my networks. I removed vlan 199 and also added a 5GHz for vlan 201 and added one dedicated Port to vlan 202.
And with the latter I have problems. First, everything looked fine. But when I restarted the Asus again, the device on the Port lost its vlan 202.

I then added the vlan1 thingy, but after a second reboot, again the port lost its vlan 202.
I really don't get it, why it is always working for the first time...

Is there something I can do about it? Did I missed something? Also why a dedicated vlan for one port seemed to worked fine but having it together with the wifi is not?

Code: 
#!/bin/sh
robocfg vlan 1 ports "0 1 2 4 5t"
robocfg vlan 201 ports "4t 5t"
robocfg vlan 202 ports "3 4t 5t"

It shouldn't make a difference whether the port is in the same vlan as the wifi bridge or on one of its own. Can you post robocfg show after a reboot?

And again, on a second reboot, not working anymore...

@grifo It seems, after a reboot, it will get a non vlan IP and will stay on it. If I refresh dhcp on the device, it will get the vlan IP. First tried with a hue bridge, then switched to a laptop and I can see this behavior now. Any thoughts?
So there is no connectivity, if its on non vlan but it doesn't reconnect itself, which is bad. ^^

Yes the robocfg vlan 1 line needs to be there if you want the port isolated to just one vlan. This robocfg show looks good and it should work.
 
@grifo But it doesn't in the sense that the device on that port will stay in the non vlan if not un- and replugged or otherwise get a new IP.

It's probably because you were making the changes so the machine couldn't get an IP and it used a self assigned IP. This shouldn't happen in normal operations once the configuration is settled. I'd leave it with your latest config, reboot the machine and monitor it.

It happens that the DHCP lease needs to be renewed when an end device picks up a wrong (while making configuration changes) or self assigned IP.

EDIT: there is a possibility of the machine picking up a wrong IP if it boots at the same time as the AP and it makes its DHCP request before the services-start script has been run, so it gets an IP from vlan 1. It's rare but it can happen and to prevent that I have the robocfg vlan lines (only) on a different script, init-start, which is the earliest script that is run. It normally only happens during testing and config changes as even if the power goes off chances are the machine will take longer to boot and make its DHCP request than it takes the AP to run all its scripts, so to keep things simpler I didn't mention it earlier.

@grifoTried this now multiple times and also waited for some minutes (even 10) and that problem persists and it is not going away. So I guess there is nothing we can do about it and I will have to stick for wifi vlans only, which is still great.
I am thinking of blocking unknown client in the dhcp server on that non vlan in pfSense. But if I forgot that setting I will have a hard time next time plugging in something new...
Or maybe drastically reducing the Default lease time for this interface in the dhcp server?

So I somewhat fixed it in pfSense by making a DHCP Static Mapping for that devices MAC plugged in that port under the "wrong" network and defined a leas time of just 60 second just for that Mapping. This seemed to work fine. But I have to remember what I did there. ;)

Now reading your edit above, maybe have to test that. But I am only rebooting the Asus, nothing more and the problem persisted.

It's strange as it works on my RT-AC68U running in AP mode with the vlan to ssid config as per the posts above and an isolated wired port belonging to the guest vlan.

Not worth doing either IMO, if it still doesn't work after you've tried all else you can always create an extra wired only vlan like the 199 you had earlier. If it has to be on the same broadcast domain you can do the bridging on the pfsense.

Could you show it to me? Want to try that too the right way.

To be honest, I only had this for testing purposes, I often unplugged and replugged the cable for this so I can't tell, if it would had this problem too.

Yes, you create another script called init-start, also in /jffs/scripts/, with the below content, per your latest config:
Code: 
#!/bin/sh
robocfg vlan 1 ports "0 1 2 4 5t"
robocfg vlan 201 ports "4t 5t"
robocfg vlan 202 ports "3 4t 5t"

And you remove the same lines from the services-start script.
 
@grifo According to my laptop, this does it. Thanks again!! :D
Code:

robocfg vlan 1 ports "0 1 2 4 5t"
robocfg vlan 201 ports "4t 5t"
