I am currently doing the preview of the V18 Certified Architect course. Working on the VPN training.
I am using EAP3R1.
I have an IPSEC VPN Tunnel running, and I go in and edit the subnet list.
When I click 'save' I get told that the PreShared Key needs to be at least 5 characters.
Checking the Config, and I am presented with the 'Change Preshared Key' so the key is there, but the Save after editing is not acknowledging the original key.
Pressing 'Change Preshared Key' and entering the key works,
This functionality will be an issue for sites where you may not know the preshared key due to other security reasons
