If you subscribe to a VPN Business plan and have added dedicated VPN servers to your account, you can use them to set up gateways and IP addresses for your organization.
To delete a gateway:
1. Log in at account.protonvpn.com with your Proton Account username and password.
2. Click on Gateways in the menu on the left. Select the gateway you want. Click the vertical three dots (⋮) → Delete.
3. You’ll be asked to confirm that you want to delete this gateway. This action cannot be undone. To continue, click Delete gateway.
You’re done. That gateway will be removed from the gateways page, and the servers assigned to this gateway can be re-assigned to new or existing gateways.
