24.7.1 update killed my UniFi internet connectivity

[dwasifar]

I have two networks defined in the UniFi controller, one for the main subnet and another for a VLAN subnet (to isolate IOT devices).

After the 24.7.1 upgrade, nothing on either wi-fi network can reach the internet.  Wired connections are fine.

I can't spare the network downtime to troubleshoot it right now, so I reverted to 24.7 and reloaded the same configuration, and everything works again.  If anyone has any thoughts, it'd be welcome for when I can look at it.

i can't say i experienced the same issue.

i have a  primary 192.168.1.1  and then IOT is 172.168.69.1  network.       all IOT Devices and primary lan all function after the update

I feel like this time it has less to do with the VLAN and more with the firewall.  Wi-fi devices get a local IP on the correct subnet, but can't reach internet.

Not sure if related or not but I had a similar issue that was caused by Unbound not able to start anymore. I was caused by my Google Home generating a IPv6 network temporarily during opnsense reboot. Once opnsense had rebooted, I saw a ULA IPv6 address on my Google Home IoT network assigned to opnsense (interface / overview). This happens even though this interface IPv6 configuration is "None". This feels related to SLAAC which is impossible to disable it seems.

For some reason, that prevented Unbound from being able to start (I'm binding Unbound to specific interfaces, not ALL as they recommend). When that happens, there are a few things I can do

- Manually remove the ULA IPv6 in command line from the Interface where my Google homes are (it usually doesn't come back once they have internet access, I suppose they do this to talk to each other temporarily during outage)
- Enable dhcpv6 on the interface, save/apply. Re-disable IPv6 (set it back to none), save/apply. (This makes the IPv6 ULA go away and Unbound is now able to start)
- Remove specific interface binding from Unbound so it binds to everything, for some reason this makes Unbound able to start even with this problem.

This is reproducible every time I reboot opnsense and only happens on my Google Home interface (which is linked to Unifi Access points which have their own SSID for my Google Homes).

Next time you upgrade or reinstall, run ifconfig in command line or check in interfaces/overview to see if you don't have an IPv6 on an interface that shouldn't be there and check is Unbound is running or not. You should have IP address access to everything even without DNS running (to access opnsense UI or command line or even ping 8.8.8.

Like I said... Could be related or not to your issue but this is my case since the last few updates and I thought I could share in case it helps.

Appreciated, thanks!  I will look there first.

An update: I had reverted to 24.7 to solve the issue.  When I saw 24.7.2 was available, I upgraded directly to that from 24.7 with no problems.

So I guess I will never know why 24.7.1 didn't work for me, but .2 seems okay.
