It is kubernetes environment, there is a Cluster scope service with 2 backends, 2 pods. The rule for this service program a load balancing between 2 chains representing each backend pod. When I curl the service, only 1 backend pod replies, second times out. If I delete pod which was working, then second pod starts replying to curl requests. Here are some logs and packets captures. Appreciate if you could take a look at it and share your thoughts. Please add counters to your rules to check if both dnat statements are hit. You may also switch 'jump' in vmap to 'goto' and add a final rule in k8s-nfproxy-svc-M53CN2XYVUHRQ7UB (which should never see packets). Did you provide a dump of traffic between load-balancer and pod2? (No traffic is relevant info, too!) A dump of /proc/net/nf_conntrack in error situation might reveal something, too. Cheers, Phil
