VPS for OpenVPN: Universal VPN Hosting with Maximum Compatibility

WireGuard gets the headlines, but OpenVPN solves problems WireGuard cannot. TCP mode over port 443 is indistinguishable from HTTPS traffic, making it nearly impossible to block on corporate networks, hotel Wi-Fi, and in countries with deep packet inspection. WireGuard's UDP-only design fails in these environments.

OpenVPN also supports a wider range of cipher suites and authentication methods, including certificate-based auth with a full PKI infrastructure. For organizations that need per-user certificates with revocation capabilities, OpenVPN's X.509 PKI is unmatched.

Two decades of security auditing, CVE tracking, and real-world deployment have hardened OpenVPN into one of the most reliable VPN solutions available. It may not be the newest, but it is the most proven.

The fastest way to deploy OpenVPN on your AnubizHost VPS is Nyr's openvpn-install script. It handles certificate generation, server configuration, firewall rules, and client config creation in a single interactive session. Adding new clients later is a one-command operation.

For enterprise deployments, install OpenVPN Access Server, which includes a web admin panel, LDAP/RADIUS integration, and per-user bandwidth controls. The free tier supports two concurrent connections; paid licenses scale to thousands.

Docker users can run kylemanna/openvpn, a well-maintained container image that stores all state in a Docker volume. This makes backups, migrations, and upgrades trivial — just move the volume to a new VPS and start the container.

OpenVPN's default configuration is conservative. A few tweaks can double your throughput on an AnubizHost VPS. Switch from the default BF-CBC cipher to AES-256-GCM, which leverages hardware AES-NI instructions on our processors. Enable fast-io and sndbuf/rcvbuf tuning to reduce kernel buffer copies.

For the best performance, use UDP mode. TCP-over-TCP causes head-of-line blocking and retransmission storms under packet loss. Reserve TCP mode for restrictive networks where UDP is blocked, and use UDP everywhere else.

On multi-core VPS plans, run multiple OpenVPN instances on different ports and load-balance clients across them. Each instance is single-threaded, so splitting clients across 4 instances on a 4-core VPS quadruples your aggregate throughput.

A 1 vCPU / 2 GB VPS handles OpenVPN for up to 30 concurrent clients at typical browsing speeds. For heavier use — video streaming or file transfers through the tunnel — step up to 2 vCPU / 4 GB.

Install takes under 5 minutes with the automated script. Download the generated .ovpn client config, import it into your OpenVPN client on any device, and connect. The server handles NAT, DNS forwarding, and routing automatically.

AnubizHost's offshore infrastructure ensures your VPN exit point is in a privacy-friendly jurisdiction. Combined with OpenVPN's strong encryption and our no-traffic-logging policy, you get a VPN that you fully control and can fully trust. Set yours up today.
