By default, there are two VLANs configured. One for LAN and another one for WAN. On the back of your device, there are 4 LAN ports and 1 WAN port, but they are all physically wired up to one switch chip. Therefore, two VLANs are necessary to seperate them logically. VLAN1 is eth0.1 (LAN) VLAN2 is eht0.2 (WAN) > Is that a synonym for upstream, or gateway? Yes, it is the connection between the switch chip and the SoC [1].
