Answer
Do VLANs automatically keep Starlink guest devices away from my private network?
Creating different VLANs is only part of the job. Devices must be assigned to the intended networks, and the gateway's routing and firewall policies must enforce the separation you want.
For example, a guest Wi-Fi name should map to the guest VLAN through the access point and switch to the gateway. An incorrect port configuration can put devices on the wrong network or leave them without an address.
Define the intended behaviour first: guests need internet access, but usually do not need your file server, printer or router-management page. Configure those restrictions using your gateway's documentation, then test from an actual guest device.
Check both wireless and wired guest connections, and account for IPv6 if enabled. Keep a known working administrator connection while making changes. A new network name or colour in a dashboard is not evidence of isolation; a successful access test is.
