Troubleshooting WireGuard Mesh Networking for Clusters (5180)
Technical Overview
Engineering breakdown of Troubleshooting WireGuard Mesh Networking for Clusters (5180). Bare-metal hardware performance requires isolated kernel parameters, proper MTU tuning, and deterministic routing tables. This guide walks through common failure modes—handshake timeouts, key rotation mismatches, and asymmetric routing—and provides systematic diagnostics using wg show, tcpdump, and eBPF tracing.
eBPF/XDP kernel filter evaluates TCP/UDP frames directly on server NIC.
