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.
