Yes. There are two types of VPNs which are both supported:
Client VPNs
Client VPNs allow you to connect to your office or third party site from you Paperspace machine. This type of VPN requires you to setup software running on the machines you would like to bridge over a VPN tunnel and does not require any changes to your account. See below for recommended client software:
Recommended Client VPN Software
We recommend ZeroTier, Himachi, OpenVPN and the default VPN service within Windows for client VPN connections. You can view our tutorial on setting up ZeroTier here.
Note: When choosing a VPN service, make sure that the VPN does not modify the primary network connection on the machine, otherwise you may lose access.
Site-to-Site VPNs
Site-to-site VPNs allow two-way traffic between your office or third party site and your Paperspace machine. This type of VPN requires adding a VPN Gateway to your account and is only available to Paperspace for Teams accounts. The site-to-site VPN Gateway does not require an agent running inside the VM. Any machines added to a Private Network with a VPN Gateway attached will automatically become addressable by any device connected to the tunnel.See our Help Center article on adding a VPN Gateway.
Tip: Always be sure to take a Snapshot when there is a possibility that a change will cause problems. That way, you can always roll-back the machine in the event causes connectivity issues.
