Fixed In Version: Doc Type: Bug Fix
Doc Text:
Cause: iptables rewriting rules Consequence: A client that uses a fixed source port and tries to connect to a service both via the service IP and directly via a pod IP may run into problems with port conflicts. Fix: An additional OVS rule was inserted to notice when this was occurring and do an extra SNAT to avoid the port conflict. Result: Connections work.
