VPN Connectivity

VPN Connectivity Reference

ZSoftly uses WireGuard for VPN access to private cloud environments.

Configuration details

Your WireGuard configuration file (provided at handover) contains:

• Endpoint: the public IP and port of the ZSoftly VPN gateway
• Allowed IPs: the private network ranges accessible through the VPN
• Private Key: your unique client private key (do not share)
• Public Key: the server’s public key

Troubleshooting

Cannot connect to VPN:

• Verify the endpoint IP is reachable: ping <vpn-endpoint-ip>
• Check that UDP port 51820 is not blocked by your local firewall
• Ensure wg-quick up wg0 completed without errors (sudo wg-quick up wg0 2>&1)

Connected to VPN but cannot reach management server:

• Check sudo wg show to confirm the handshake succeeded (should show a recent latest handshake)
• Verify the management server IP is within the AllowedIPs range in your config
• Try ping <management-server-ip> from the command line

Need a new VPN config (lost key, new device):

• Contact ZSoftly support. A new config requires generating a new key pair on the server
