Three Python scripts send real packets from the kind node through the full relay path (biscayne → tunnel → mia-sw01 → was-sw01 → internet) and verify responses come back via the inbound path. No indirect counter-checking — a response proves both directions work. - relay-test-udp.py: DNS query with sport 8001 - relay-test-tcp-sport.py: HTTP request with sport 8001 - relay-test-tcp-dport.py: TCP connect to entrypoint dport 8001 (ip_echo) - test-ashburn-relay.sh: orchestrates from ansible controller via nsenter Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
