OK, I will merge the pull request when it's ready, leave the commits as is when I merge it, and leave the branch after I've merged it. |
When a pod is accessing a local host, it should not get SNATed as the host when it is in a nat-outgoing ippool. (a) it is unnecessary as the local node can be accessed and (b) there is no way to return the traffic as is it would return to the host itself. refs projectcalico#7252
