​
1. OpenVPN Configuration

If you provide an OpenVPN configuration file (.ovpn), we can securely load it onto your team’s dedicated test runners. These runners have built-in support for OpenVPN, allowing them to initiate a secure connection directly to your private network.
  • Typically UDP 1194 but up to you how you want to configure this as long as we have a client configuration file.
  • Expect source ips from our range 199.4.212.0/23.

​
2. Site-to-Site IPSec Tunnel

We support establishing site-to-site IPSec tunnels with customers whose network appliances or cloud environments support it. This method creates a persistent, encrypted tunnel between our infrastructure and yours. For context the tunnel will be coming from GCP Cloud VPN.
  • Tunnel protocols: UDP 500, UDP 4500
  • We will provide local subnet during configuration to ensure it doesn’t overlap
  • We will exchange a Pre-shared key (PSK) during configuration
  • We will exchange public gateway IPs during configuration
  • Supports IKEv2 or IKEv1

​
3. Linux Client-Based Solutions

If your organization uses Twingate, Tailscale, or similar VPN mesh services, we can install the appropriate Linux client on a dedicated proxy machine. This proxy can then securely relay traffic from your team’s test runners to your internal network. Known supported options:
  • Tailscale
  • Twingate
