pppe264-diag --test=full-compliance --duration=300s Look for the line: Result: FULL_COMPLIANT (All 47 test vectors passed) . If you see PARTIAL or CORE_ONLY , your stack is not true . Common Misconceptions Debunked Myth 1: "pppe264 full is just marketing jargon for 256-bit PPP." Reality: As explained above, the 264-bit space, dual authentication, and mandatory FEC create a measurable difference in both performance and security.
"You can run pppe264 full over Wi-Fi." Reality: Only if you have 160MHz channels and extremely low interference. The nanosecond jitter requirements fail on most consumer Wi-Fi 6 hardware. pppe264 full
"The 'full' version is always backward compatible." Reality: Backward compatibility is optional in the spec. Many pppe264 full implementations disable fallback for security reasons, so check your config.
