Outbound VPN

Route your server’s outbound Internet traffic through a VPN for privacy. An outbound VPN is like sending your mail through a proxy — the recipient sees the proxy’s return address, not yours.

Use Case

You might want an outbound VPN to:

• Hide your IP address from external services your server connects to.
• Prevent ISP monitoring of your server’s traffic.
• Route sensitive services differently — for example, send Bitcoin traffic through Mullvad while leaving everything else on the default gateway.

Adding an Outbound VPN

To add an outbound VPN, add a gateway using a WireGuard configuration file. There are two options:

Both options hide your home IP address, and in both cases the provider knows who you are. The difference is that a commercial VPN shares IPs across thousands of users, making it harder for external observers to correlate traffic to a specific person. With StartTunnel, the VPS IP is yours alone, so all traffic from it can be linked together. The advantage of StartTunnel is that a single gateway handles both inbound and outbound traffic.

System Default

By default, StartOS dynamically selects which gateway to use for outbound traffic for optimal performance (“Auto” mode). You can override this under System > Gateways > Outbound Traffic by switching from “Auto” to a specific gateway. This forces all outbound traffic for everything on the server through the selected gateway.

Per-Service Overrides

You can override the system default on a per-service basis by navigating to a service and going to Actions > Set Outbound Gateway. This lets you route individual services through different VPNs while leaving others on the default.

For example, you could route your Bitcoin node through Mullvad for privacy while leaving Nextcloud on the default gateway for better performance.
