| Doc Text: |
Cause: For hairpin traffic (traffic originating in a member of a Service, redirected by the load balancer to the same member) OVN changes the source-IP of the packets to IP of the LB. This affects OSPs with ovn-octavia-provider.
Consequence: If Network Policy is applied it may happen that such traffic will be unnecessarily blocked.
Fix: Kuryr, when handling a Network Policy will also open traffic from IPs of all the Services in the NP's namespace.
Result: Hairpin traffic will be allowed in OSP deployments using ovn-octavia-provider.
