I am using OpenWrt 21.02.0 on TP-Link Archer C7 v5.
I have just started setting up a few VLANs and while my devices within the VLANs can talk to each other I am not sure what the best practice is regarding giving a client access to multiple VLANs.
As an example: I would like to run Home Assistant in a Proxmox VM and it should have access to almost all the other VLANs (especially the IOT VLAN of course).
I could add a virtual NIC with the right VLAN-tag to the Home Assistant VM for every VLAN Home Assistant should have access to. But (if I am understanding it correctly) I could also write a forward rule to forward packets between Home Assistant and the other devices.
Now I am wondering what's the best way of allowing inter-VLAN-connectivity.
This is probably a very basic question and I am sorry, but I am unsure what's the best solution here.
If I should do something else I am fine with that too, I'd just like to avoid having to redo my VLANs/setup later on.
Any help is appreciated, thanks!
