Modern VPN solutions have dramatically simplified deployment compared to traditional IPsec tunnels. WireGuard with just 4,000 lines of code offers speed and simplicity, OpenVPN provides broad compatibility, and Tailscale delivers a zero-management mesh network. The choice depends on performance requirements, number of users, and the level of automation you need.
WireGuard¶
sudo apt install wireguard
wg genkey | tee privatekey | wg pubkey > publickey
# /etc/wireguard/wg0.conf
[Interface]
Address = 10.0.0.1/24
ListenPort = 51820
PrivateKey = <server-private-key>
[Peer]
PublicKey = <client-public-key>
AllowedIPs = 10.0.0.2/32
WireGuard is implemented directly in the Linux kernel, which means minimal latency and maximum throughput. Configuration is simple — a key pair and allowed IPs. The downside: manual key management and configuration for each peer. For more than 10 users, consider automation via Ansible or switching to Tailscale.
OpenVPN¶
A traditional solution with broad compatibility across all platforms. It supports both TCP and UDP transport, certificate and user authentication, and complex routing scenarios. Configuration is more complex and requires PKI infrastructure. Ideal for enterprises with an existing certificate authority and audit requirements.
Tailscale¶
curl -fsSL https://tailscale.com/install.sh | sh
sudo tailscale up
Tailscale, built on WireGuard, eliminates all manual configuration. Automatic NAT traversal, key distribution, and mesh topology are handled by the control plane. You have a working VPN in under a minute.
Comparison¶
- WireGuard — fastest, lowest latency, manual key management
- OpenVPN — most compatible, slower, rich authentication options
- Tailscale — zero-config mesh, for teams, simplest deployment
WireGuard for Performance, Tailscale for Simplicity¶
WireGuard is the standard for new deployments requiring maximum performance. Tailscale for VPN without infrastructure management. OpenVPN for legacy and enterprise environments with existing PKI.
