pfSense's new UI does not work for me...
After a review of the new UI, I already discarded it :
1-Despite SAML is listed as a type of Authentication Server, we can not configure one...
2-I use HAProxy for both Internet and local services but HAProxy is nowhere to be found in the new UI...
3-Despite I fixed the problem about the missing serial number in the BIOS of my Proxmox VM, the new UI keeps complaining that it is not licensed...
4-Basic tasks like package management are not accessible because the new UI says that this feature is restricted to properly licensed installations
5-Same for update management
So with all of this already identified, it is clear that I will have to use the original UI for many basic and essential tasks. As such, there is no reason to log in and out from new to old to new according to what I need to do. That new interface is far to be complete and ready, so I will stay with the good old one...
EDIT: Great! Now it broke my entire licensing, even in the old UI. I can no longer check for updates because pfSense says that my system is not properly licensed but when I go in Register in the System menu, it says that I do not need to register because the installation is already recognized as legitimate.
Really, do not even try the new UI or you may brake and lose your license like me!
