pfSense with OpenWRT Guest logon with VLAN

Cool_Corona

You dont need OpenWRT to handle that.

Use a range extender together with pfsense and a VLAN capable switch.

This works like a charm creating the networks you need and letting pfsense handle VLANs.

@ramosel really? Sure why not - I could do that ;)

But why doesn't it show a little radio icon, when your lan shows 2?

BTW - why do you have guesttest on channel 10? Channels to use for 2.4 are 1,6 or 11.. That wouldn't be the reason for your issue - but not a good channel to choose..

John, you are so right.. But, it's my "testbed" for this guest network issue. I live in a Loooong house stretched out across a mountain side in a T shape with the vertical element of the T traveling up the mountain. My "production" WAPs ARE on 1, 6 and 11... at the end points of the T. That way I get pretty good coverage when I'm out on the tractor or excavator too. The "testbed" WAP lives in the TE closet under the house farthest from 11.

I'll get a WRT3200ACM loaded and configured up to my current working point. My email is on my profile page. Send me a shipping address and I'll get it off to you.

PS: I think I need to fix my profile... my age is off by about 40 years?!?!

WAP lives in the TE closet under the house farthest from 11.

If its farthest from where 11 is, then it should also be on 11 as well.. There is really no reason to ever use anything other than 1,6 and 11.

but since I don't see how you have any radio assigned to this new network your calling guesttest and on this port with .10 vlan ID - how would anyone connect to it?

stephenw10

Mmm, this sure looks like a bridge problem.

This shouldn't be that difficult, it something OpenWRT does all the time in comercial deployments. Been a while since I've tried it. But not so long I've never seen LuCI

When you associate the VAP with the LAN network clients are able to connect to it? So not a wireless issue?

Might be easier to spot the problem from the uci output at the command line. I'm betting there's a missing device on the bridge....

I agree Steve, it shouldn't. But it's been evading me and ideas seem to have dried up on 3 different OpenWRT specific forums... So either I'm a complete doofus newb, I'm trying to do something that can't be done or there is some nuance I and others haven't stumbled into.... yet. I fully take this as my screwup if someone finds the problem. The DSA is a good step forward but I admit I don't really, fully understand it. As far as bridging goes, one can only make changes on the br-lan device. But at this point, ANY change I make to "Bridge VLAN Filtering" causes a lockout condition... no big deal, you wait 90 seconds and revert when the option presents. Since I am not using the WAN, I assign it to the br-lan and use that for the back-haul connection. Currently I have the default SSIDs set with different names so I can readily test connections to them. But in production, they would be the same. I also have 802.11r on all SSIDs. I found if I had it on the default wireless everything worked fine. But once I built out the GuestTest, if I didn't enable 802.11r on the Guest wireless, the default wireless (on the same radio) would reject logons, not fail the password, just reject logon. DTIM is set to 3 as Apple products seem to like it better. I do not enable IPv6 anywhere in the home network. I've also removed the native (cut down) version of WPAD and installed the full version. dnsmasq, firewall and odhcpd are all disabled since these are run as dumb APs.

Ok, I need to test this but I think your problem here is that you only actually have one bridge device. You have created a VLAN device and named it br-lan.10 but it isn't a bridge device.

We can't see you're switch config there but can I assume WAN is eth0? Or that could be the internal port connected to the switch?

What I would do though is create a VLAN device on the uplink ethernet port. Then create a bridge device with that VLAN as a port. Then create an interface using that new bridge. And then add the VAP to that interface.

I have to wait until later to test it to avoid angry Facebook users.

No problem, I can wait. Lets not PO the Facebook folks... The ones in Berkeley are liable to call 911... again... (not joking). This isn't an urgent thing, just something that needs to get done. I've been banging on it for a while now... I guess it's a route few follow. But I prefer to let pfSense do all the routing, rules, vlans, dhcp, etc... as it does it so much better. I just need it to flow to dumb APs

What you describe is how I tested it under ver 19.07,9? But that was still SWConfig. Under the new version (now 21.02.3) and going forward, they are DSA you just don't have that path... that I see. I could very well be wrong.

Forgot I had an AP300 already setup.

So, yeah, this works:

root@AP300:~# uci show network
network.loopback=interface
network.loopback.device='lo'
network.loopback.proto='static'
network.loopback.ipaddr='127.0.0.1'
network.loopback.netmask='255.0.0.0'
network.globals=globals
network.globals.ula_prefix='fd21:90da:7fd9::/48'

network.@device[0].name='br-lan'
network.@device[0].type='bridge'
network.@device[0].ports='eth0'
network.lan=interface
network.lan.device='br-lan'
network.lan.proto='dhcp'
network.lan.delegate='0'
network.@device[1]=device
network.@device[1].type='8021q'
network.@device[1].ifname='eth0'
network.@device[1].vid='1001'
network.@device[1].name='eth0.1001'
network.@device[2]=device
network.@device[2].type='bridge'
network.@device[2].name='br-guest'
network.@device[2].ports='eth0.1001'
network.GUEST=interface
network.GUEST.proto='dhcp'
network.GUEST.device='br-guest'
network.GUEST.delegate='0'

Then:

root@AP300:~# uci show wireless.wifinet2
wireless.wifinet2=wifi-iface
wireless.wifinet2.device='radio0'
wireless.wifinet2.mode='ap'
wireless.wifinet2.ssid='AP300-Guest'
wireless.wifinet2.encryption='sae-mixed'
wireless.wifinet2.key='1234512345'
wireless.wifinet2.ieee80211w='1'
wireless.wifinet2.network='GUEST'

Clients connect to that and pull a lease from a dhcp server on VLAN1001.

That's a 21.02 snapshot:

root@AP300:~# uname -a
Linux AP300 5.4.143 #0 Mon Sep 6 02:58:45 2021 mips GNU/Linux

There is no switch on that device so DSA doesn't come into play. I'm not sure how those devices you have are laid out in hardware but if it has only one internal NIC you would need to configure the switch. However it looks like you already did that bit correctly since the vlan assigned as an interface is pulling a lease in the correct subnet.

Steve

Ramosel

@stephenw10 The (network.@device[1].ifname='eth0') is throwing me. If you are in LuCI and select the dropdown for network, is there a "Switch" entry under Interfaces and Wireless? Or do you get Interfaces and Wireless with no Switch?

Sorry, botched that, had to edit.

stephenw10

No there's no switch in the AP300, it's an access point.

What's the hardware layout in the WRT3200ACM? Is this correct for your version?
https://openwrt.org/toh/linksys/wrt3200acm#switch_ports_for_vlans

If so and you are using the eth1 (WAN) port as the uplink you should be able to create the VLAN there and then add that to the new bridge device. I've used eth0 because that's the only port on the AP300.
You could create it on eth0 (the internal switch port) on your router but then you need to configure the switch to trunk that VLAN. Or use port based VLANs to just pass it.
It looks like OpenWRT will also allow you to create a VLAN on the bridge interface which is what you have done. For me that's less logical. YMMV!

There's probably several ways to do this. It's definitely possible.

Steve

stephenw10

Oh, wait think I read that switch diagram wrong. So the hardware actually has 5 physical ports? LAN 1-4 and WAN?
In fact both actual NICs (eth0 and eth1) are connected to the switch on internal ports 5 and 6?

If you're using port VLAN mode (not 802.1q) then all VLAN traffic is passed. So create a VLAN interface on eth0. Create a bridge device with that in it. Create an interface with the new bridge. Assign the guest wifi to that.

There are in fact numerous ways you could do this depending what you want.

Steve, I wasn't talking about the AP300 hardware, but in the OpenWRT LuCI, under the Network tab, does it show "Switch"?

Yes, the WRT3200ACM has 4 ports plus the WAN port.

stephenw10

No I don't see a switch menu in LuCI because there's no switch to configure.

What is your switch config currently?

Ramosel

@stephenw10 said in pfSense with OpenWRT Guest logon with VLAN:

I'm not really sure, there is no "Switch" function on a full DSA... that's where I think I was getting hung up on your suggestion. Ver 21 has moved to DSA... but only for some devices and the tell is whether you have the "Switch" function or not. But I digress. I follow your suggestion starting at "Create a bridge" device...". I'm not following you on "create a VLAN interface on eth0". Please elaborate.

Thanks,
Rick

stephenw10

Hmm, well there must still be a way of configuring the switch IC. Look at the full uci show output. What's in there that relates to the switch ports?

But since you already created VLAN device and then when you added it as an interface it correctly pulled a dhcp lease from that VLAN implies however you have switch configured it must be passing the traffic.
However you created it on the existing bridge device which is not logical to me. Maybe it could work.

I suggest you remove the VLAN device you created and instead create on eth0. Then create the bridge on that. Then the interface as the new bridge device.
Now when you are adding the VAP to the new interface you are adding it to a bridge and not to a VLAN. And underneath the OpenWRT config Linux still needs to bridge the traffic between those interfaces which is I think what was failing for you.

I know YOU know what you are talking about and trust you are right. I'm starting to feel like an idiot. I can't even get to the VAP point of this as I can't make what you have lined out work (again, starting with the interface as a DHCP client to verify connectivity with the pfSense supplied VLAN and DHCP server).

Am I reading/following your suggestion wrong?

Create the VLAN 10 device 802.1q with eth0 as the base device = eth0.10
Create a bridge for software VLAN eth0.10 and Switch port WAN = br.eth0.10
Create the Interface for my Guest function as a DHCP client and the device is br.eth0.10

The Interface never gets an address. Lots of outbound packets, nothing inbound.

I'm sure I'm doing something wrong... just not sure what?

stephenw10

Ok, having read this and this, specifically this: https://openwrt.org/docs/guide-user/network/dsa/converting-to-dsa#wireless

I can absolutely see why you have it configured as you do and might expect it to work like that.

I also find myself beginning to hate the DSA with a fiery passion!
It seems like it hides half the ports presenting them to you as though they are interfaces and 'helpfully' adding all the VLANs and switch settings for you. Which I hate. But even more so when it doesn't do it correctly!
No idea how you know which eth ports the switch is using internally or how they are configured if you want change that....

So, according to that doc, you should be able create the VLAN device on the bridge as you showed. And you should be able to add the wifi network to it directly. But you will have to enable bridge VLAN filtering in order to have the VAP added to the bridge with the correct tags by whatever dark magic powers DSA.

Or just pretend the switch doesn't exist since we know without VLAN filtering enabled it just passes all VLAN (port based vlan mode) and do what I outlined above which still works fine in 21.X.

OK, I had to chuckle at "fiery passion"... but then the reality of "This is MY problem and I still haven't resolved it" set in.

The best clue I have as tho which eth port is in play comes from the Network/Devices.
It only shows "eth0". And, that does correlate with the information as you too found on the OpenWRT site regarding the WRT3200ACM.

stephenw10

Mmm, it does look like it's only using eth0 and eth1 is simply ignored. That's fine for you in an access point config since you're never routing traffic between Ethernet interfaces. Any traffic there should just be switched. Though we just have to hope that's happening since we can't see how the switch is configured. And the gui makes it look like they're bridged which would be a very bad setup! </rant>

Anyway it looks like you can do this two ways:

Enable bridge VLAN filtering and add the correct VLAN tags so DSA knows how to configure the switch for 802.1Q mode when you add the VAP to it.

Or leave bridge VLAN filtering disabled and treat it like a dumb switch. In which case setup the VLAN device and additional bridge as I outlined.

One interesting thing here is the screenshot in the doc here.

Wireless interfaces will automatically be included in the bridge and belong in the correct VLAN.

You can see that command they use shows exactly that. The VAP device, wlan1-1, is added to the bridge on a VLAN. I suspect that is what's not happening in your current setup. However I have no idea what command was used to check that. It's not anything default in OpenWRT. The closest I got to it was installing the bridge package and then running brctl show. That doesn't show VLAN info me though. [Edit: I see it's a standard Linux command to show the vlans in a bridge, just not included in openwrt]

Steve

stephenw10

Oh here we go you can install the ip-bridge package and then:

root@AP300:~# bridge vlan show
port              vlan-id  
eth0              1 PVID Egress Untagged
br-lan            1 PVID Egress Untagged
br-guest          1 PVID Egress Untagged
eth0.1001         1 PVID Egress Untagged
wlan1             1 PVID Egress Untagged
wlan0             1 PVID Egress Untagged
wlan0-1           1 PVID Egress Untagged
root@AP300:~# bridge link show
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 master br-lan state forwarding priority 32 cost 4 
10: eth0.1001@eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 master br-guest state forwarding priority 32 cost 4 
13: wlan1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 master br-lan state forwarding priority 32 cost 100 
15: wlan0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 master br-lan state forwarding priority 32 cost 100 
16: wlan0-1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 master br-guest state forwarding priority 32 cost 100

So you can see the two bridges I have and the members in them. And since I do not have vlan filtering enabled on either they are all set as VLAN 1 and passing all traffic. Which includes vlan1001 tagged packets here.
