Hello Oracle Community,
The documentation on the website: https://docs.oracle.com/en-us/iaas/Content/File/Tasks/securitylistsfilestorage.htm indicates that 4 sets of rules must be configured for mount a File Storage (Scenario A):
- Ingress Rules for the Mount Target with configured TCP/UDP destination ports (Necessary Rule)
- Egress Rules for the Mount Target with configured TCP/UDP source ports (Unnecessary Rule)
- Ingress Rules for the Instance with configured TCP/UDP source ports (Unnecessary Rule)
- Egress Rules for the Instance with configured TCP/UDP destination ports (Necessary Rule)
I consider that rules 2. and 3. are unnecessary since the documentation indicates that they are Stateful Rules, to verify this I made a use case (attached) and I verified that it is possible to mount an NFS without adding the mentioned set of rules, I also came across a YouTube video from 6 years ago in which explains the inbound rules to configure from the Mount Target perspective where rules with source ports are not required, the video is the following: https://www.youtube.com/watch?v=oW21K3eg_Qg My question is: Why was it not previously requested to configure Egress Rules with Source Port from the Mount Target perspective? Is it possible that ruleset 2 and 3 are not required?

1. Ingress Rules for the Mount Target (Necessary Rule)

2. Egress Rules for the Mount Target (Unnecessary Rule?)

3. Ingress Rules for the Instance (Unnecessary Rule?)
