I have setup a seperate vlan for iot stuff. Everything has been working fine until recently, but now devices on the iot vlan can no longer communicate with the other network. I have setup firewall rules around this to specifically only allow them to connect only to the mqtt server on the other network. But even removing all rules and adding additional rules to allow absolutely everything to every private IP does not fix it. From the regular default network I can however access the devices on the vlan just fine. So it works one way.
Can’t pinpoint what changed tbh. I do not remember changing anything recently. Only noticed that all the things that connect via wifi in home assistant are gone.
I did reinstall the controller now. Used the linuxserver.io docker container. Previously it has been on some debian 10 vm that I now retired. Restored from backup, re-adopted everything. Same issue, but now running the most recent controller version.
The firewall rules are setup like this
(there are a few more rules below that, but they are all system managed can´t edit them)
I did try to disable the block inter vlan rule, added an addtional rule to allow the iot network to connect to all private ips (it´s gone now) and tried to disable the gateway management rules too. I connected my notebook to the network. Same thing cannot connect to anthing. Can connect to the internet if I disable that rule. Can connect to the gateway management ui’s (if i disable those rules) also the one on the regular network. Can also connect to devices on the same vlan, but not devices on the regular network (except management ui).
Not really sure what to share tbh. I do not believe that this is a firewall issue at this point, but something else that is not working out.
