I took a also a deep look into how to deal with VLANs so I restructed the network configfiles, to be split by ports * sw0 - switch * mgmt for mgmt access * ge0/ge1 for tagged & untagged trunk access * node[1234] for untagged access and if needed add further tagged vlans See https://github.com/j0ju/sbc-fw-alchemy/tree/main/turingpi2-alpine.Dockerfile.d/200_seed_config.sh.d/etc/network/interfaces.d
