Description

The nat_open metric exposed via the /metrics endpoint and the lighthouse/ui/health endpoint doesn't seem to be reporting the status anymore on latest unstable. It seems to be related to the change from #5314.

Version

unstable (v5.1.0 release candidate)

Present Behaviour

• nat_open metric not available on /metrics.
• nat_open always false on lighthouse/ui/health even when the node is reachable from external nodes.

Expected Behaviour

nat_open metric should be available and should return true if node is reachable.
