Troubleshooting pfSense requires a systematic approach: starting from physical connectivity and interface status, progressing through firewall rule analysis, routing table inspection, and service log examination. pfSense provides comprehensive diagnostic tools through both the web interface (Diagnostics menu) and the console (shell, pfTop, tcpdump).
