upgraded to pfsense 2.8.0, WiFi devices report intermittent 'no internet access'

You shouldn't have to you just need to make sure traffic is opening states on the correct interface.
Do you have bridge filtering set to the bridge members or the bridge itself?
Do you have the bridge assigned?

@stephenw10
I only have the bridge because when adding external AP the tutorials I looked at said I need it.
I don't have it assigned to anything. I don't filter on it. I don't explicitly use it for anything.In 'Floating' rules I had entries because under WiFi interface I have a rule that WiFi should not go out to 'LAN subnet'. I don't want WiFi devices to reach my LAN in general, unless explicitly allowed (via rules). Sometimes, the "WiFi Client" from the picture with Floating rules I posted reached my LAN and I wasn't sure why so I put a Floating rule to forbid it. The Floating rules are executed before any other in the firewall.
-
@skubany2 your last rule there where you say don't allow lan access is wrong.. That is a ! lan subnets - it would block everything that is NOT the lan subnets.
none of those rules show any hits..
-
I would guess that traffic from the clients is coming in the WIFI interface and going out the LAN because that's where the subnet is defined. The bridge allows that to work because everything uses the same subnet but pf sees that as asymmetric.
Unless you need to filter between the wired and wireless segments you should move filtering to the bridge, assign the bridge and add the subnet on the bridge directly with neither member having a subnet defined.

This is such a borked up config.. Why are you bridging? Why would you bridge if you don't want to allow wifi talk to lan?
I take it your again hiding your rfc1918 space where you put in wifi clients - so these are different networks - again why bridge?
What exactly are you trying to accomplish - there is almost never a good reason to bridge..
If you want to leverage a port on pfsense for your AP - then put it on its own network, and just allow what you want. If you want wifi on the same network as lan plug your AP into your switch.
If you want multiple networks on your AP via vlans and one of those is your lan network - then have a vlan capable switch and again plug your AP into your switch.
-
Commonly such a setup is used when you want to have wired and wireless clients in the same subnet but also want to filter traffic between them.
I hadn't, until now, considered how interface bound states might affect that.
But, I agree, it's almost always better to just use two subnets and not bridge them.

You are right, I misspoke. The "WiFi Client" is not supposed to go out to the internet. I almost never use that client though. -

The config is at least 8 years old. I used to have pfSense run on a laptop with WiFi adapter. When moving my pfSense to a custom PC I decided that it is more flexible to have an external AP rather than internal. That way I can change AP in the future easily. Also choice of AP would not be dictated by support provided by Unix on which pfSense is based. To add an external AP to pfSense I jumped online to see how others do it. The tutorials I saw used bridging and so did I. I didn't really understand why but it worked so I was happy. I'm more versed now at working with pfSense and understand networking better than in the past, though as you can see I'm far from an expert.
I will be going (attempting) the route of running AP off of a dedicated pfSense port. This will give me the separation of LAN and WiFi and should work with 'Interface Bound States' in pfSense. I have an idea how to achieve that, so we'll see if it works.
-
Yup that will work if you don't need them on the same subnet.
Or moving the filtering and subnet assignment to the bridge interface would also work.
-
I am now configured with 'Interface Bound States' and no longer bridged.
Thanks for your help guys.
I like this way better. Better organized and more precise.
-
Nice. Yes that's a much better setup if you don't need them on the same subnet.
