ER605 + TrueNAS networking = containers on different VLANs than host?
I'm trying to configure my ER605 (10.1.1.1 on MGMT VLAN 1) with a TrueNAS (Scale 25.10) server (10.1.2.2 on INFRA VLAN 2). My Omada Controller (in a custom app using Docker Compose YAML) lives on the TrueNAS server - I want to move it (somehow) to VLAN 1. My Jellyfin server also lives on the TrueNAS server as a Docker (Compose) container (outside the TrueNAS Apps system) and I want to move it to my Media VLAN.
Can this be done? I've tried all manner of combinations of ER605and TrueNAS networking settings and so far, I haven't found a way. Unless someone can tell me otherwise, it would seem my options are:
Live with the Omada Controller and Jellyfin on VLAN 2
Move the Omada Controller to a different host (and/or buy an OC200) + move Jellyfin to another box. (I'd hate to do that since the whole point of my TrueNAS server was for holding all my media.)
Buy a managed switch that supports tagged and untagged VLANs, PVID assignment, trunk/access semantics, and multiple VLANs per port. (But I'm afraid that some ER605 limitation will still end up tripping me up.)
