I do not understand this rule. If you jump to KUBE-SVC chain from KUBE-XLB chain. Then it may reach any backend pods right?

Oh I see the bug now. You want to allow pods on the node to access the LB.

LGTM

cherry pick it for 1.4? Or since it is alpha, do not care.

@bprashanth you mentioned that this might partially fix #33081. Which part does this fix?

@kdima the blackholing part. You just get dnatted to your endpoints, not out to the public lb and back down to your endpoints.

@bprashanth I have just tried out this patch on our cluster and it still does not seem to work. Turns out I made a mistake in the setup. Everything seems to work! Thanks for fixing this

I didn't actually change anything, just rebased, so I'm re-applying lgtm

I would say the failure is from this pr at this point but I've seen identical failures across the board.

This change is prime suspect for drastic increase in flakiness of the [Feature:ExternalTrafficLocalOnly] e2e test.

Remove onlyLocal NodePort e2e till pr #33957

We were basically testing this bug: #30809
We fixed the bug: #33587, but forgot to remove the "test". 
This pr adds a test for the new feature: #33957 (ensure that nodePort with onlyLocal works only on nodes with endpoints and fails otherwise)

fixes #34124
