I deployed a cluster without enabling IPsec and tried to send ESP traffic between nodes. I was unable to do this which suggests that ESP traffic is being blocked. This is probably requires firewall rules to enable IKE, ESP and Nat-t traffic.

@anurag,  I guess this issue should be fixed according to above comment. could you help double confirm this?

Changes were made for the IPI installation path but not for the UPI installation path. Similar changes need to be made for UPI as well.
