Pi Alert VLAN issue (lemmy.world)

I recently discovered Pi Alert (and the various forks of it) and it seems like something that might be useful on my homelab.

I've decided to use this version, and have tried the others as well, but I can't seem to get it to discover things outside of the VLAN that it is installed on.

It is running on a Proxmox VM using a trunk'd interface that has several VLANs available to it. If I SSH into the VM hosting Pi Alert, I am able to ping the devices on the other VLANs without issues, so I know ICMP detection should be working.

Here is the config section. I am using SCAN_SUBNETS = [ '192.168.1.0/24 --interface=ens18', '192.168.2.0/24 --interface=ens18' ] To test 2 of my VLANs, and as mentioned, they are on the same interface, however this does not seem to be working.

Anyone have any suggestions?

Right. Most of my VLANs are set up that way; they're silos. The VLAN that this is running on is the "management" VLAN that can see the other ones
