Step 2: Create a CA, an server certificate, and a server instance
Step 3: Configure server settings protocol, port, tunnel network, local subnet
Step 4: Add client certificates for each user/device
Step 5: Create firewall rules to allow OpenVPN traffic and set up NAT if needed
Step 6: Export client configurations and import on client devices
Step 7: Test client connection and logs for troubleshooting
Quick tip: OpenVPN uses UDP for better performance; consider TCP only if you’re in a restrictive network.

C. IPsec on OPNsense

Step 1: Configure a new IPsec tunnel phase 1 and phase 2
Step 2: Set up proposals encryption, authentication, DH groups
Step 3: Create a tunnel interface and assign it to relevant networks
Step 4: Add firewall rules to permit IPsec traffic ESP, ISAKMP, NAT-T
Step 5: For site-to-site, configure matching settings on the remote gateway
Step 6: Test with ping and verify tunnel status in the IPsec status page
Quick tip: For site-to-site, ensure MTU considerations are aligned across sites to avoid fragmentation.

Performance and security considerations

WireGuard typically delivers higher throughput with lower latency, especially on modern CPUs with hardware acceleration.
OpenVPN is versatile and reliable but can be more CPU-intensive. If you’re on older hardware, WireGuard may outperform.
