Peer relay forwarding high packet volume indicates suboptimal routing topology

How to detect:
The local peer relay instance is forwarding significant packet or byte volume, as indicated by tailscaled_peer_relay_forwarded_packets_total or tailscaled_peer_relay_forwarded_bytes_total metrics. This suggests the node is acting as an intermediary for peer-to-peer connections that cannot establish directly.
Recommended action:
Monitor tailscaled_peer_relay_forwarded_packets_total and tailscaled_peer_relay_forwarded_bytes_total by transport_in and transport_out labels. High relay volume may indicate network topology issues preventing direct connections. Consider reviewing firewall rules, NAT configurations, or enabling subnet routing for more efficient paths.
