I have 5 subnets/vlans configured and 1Gbps cable Internet. I have this weird speed issue where if I'm on any subnet/vlan besides the default LAN (no vlan tag and the interface configured when installed from scratch) I get full speed a la speedtest. If I connect to LAN, I only get ~250Mbps. It's really weird. All the rules and settings are identical on the interfaces.

Thoughts?

Attaching some screenshot of the layout.

Heh. Does everybody try mixing tagged and untagged VLANs on an interface? And here I thought I and the other thousand folks here who've done it were special.

FreeBSD has trouble passing the correct entrance interface to pf when mixing tagged and untagged frames. What's surprising is your setup functions at all. I imagine it depends on your ruleset - a permissive one might work. But try switching LAN to a VLAN (tagged) interface (without locking yourself out...) and see if it helps. Also, virtual Ethernets can have some odd performance characteristics relating to "hardware" offloads, but not having used/planning to use such, I've paid limited attention.
