First Homelab in the making and it’s been an wonderful process learning everything. I am using a Protectli 4 port device running pfSense, an 8 port UniFi managed switch and a Raspberry Pi Cluster for now. I have an IoT VLAN created for these devices on a singular port on top of my already configured LAN setup by default. If I decide to create more VLANs, which I’m sure I will, what interfaces should I assign them too. I am having a hard time finding literature on when to create a VLAN and if you do should you put multiple on one interface or create them on separate interfaces. Like igc0 has my IoT VLAN and LAN should my other VLANs go there or like igc2 for example. Sorry for the long message just curious about industry standards and best practices.
depends on the amount of expected inter vlan traffic. If the Vlans don‘t talk much to each other you can all put them tagged on the same port on your firewall. If you expect a lot of traffic between the vlans put them on a separate interface on the firewall. then connect them to your switch on ports that are configured as untagged and have the correct vlan assigned.
