I plan on filling this page with weird configuration notes for various things. Hopefully someone will find this useful.

Ubiquiti notes regarding using the LAN2/WAN2 port on a USG firewall.
- In the VLAN config, you have to add the VLAN to the LAN2 "Network Group".
- Even after you do this, the LAN2/WAN2 port will use TAGGED packets, not the native VLAN. So the port you are using on your switch needs to have native VLAN 1, tagged VLAN 2.  (Assuming your VLANs are numbered 1 and 2.)
