Connection timed out from pods within the same cluster

What Happened?

I had to reimage my system and therefore reinstall (rootless) Docker and Minikube. After this, I'm having an issue where my pods within the cluster cannot access each other via ClusterIP services.

I can access these same services from my host machine using kubectl port-forward. I have no issues when applying the same object configurations to a local Kind cluster, or very similar configurations to GKE.

Running Minikube v1.32.0 on Debian Trixie.

Can still reproduce in Minikube v1.33.1

After finding #16962, I ended up getting things working by setting net.ipv4.ip_forward=1 on my host machine. It looks like that issue may affect rootless Docker as well.
