I haven’t tried OpenVPN, but I would be curious about the performance. Although it’s a small CPU, it does have some crypto extensions that might aid with OpenVPN/tunnel performance. Here’s the lscpu output, which shows that the CPU does have AES and several checksum extensions, so OpenVPN performance may not be too bad.
