OPNSense training? (official or otherwise)

[granute]

Hey, folks.

I've been using OPNSense for increasingly more complex tasks starting about 2 years ago. I have fairly solid (decades) experience in networking. However I've been struggling to get some of the Wireguard site-to-site stuff to work as I expect even when working against both the official docs and various YouTube examples. I've come to the conclusion that I might have more luck if I were able to go top-to-bottom on some training; either paid in-person or some sort of remote (YouTube) training that was not aimed at a specific task but instead at understanding all of OPNSense from Interfaces, Gateways, and all of the other pieces in the "object model".

It terms of any attempts to go top-to-bottom I've only found the video series from PhasedLogix IT Services on YT. Hopefully not much has changed in 2 years since the series was started.?.

But perhaps others have advice on comprehensive resources?

ty!

Given that I did not get any response from my previous question about OPNSense training...

Curious if anyone who has a lot of experience with OPNSense and pfSense has any insight as to how training in pfSense might translate to OPNSense? Now, let me be clear... Obviously there are some dramatic differences in the UIs and some less dramatic differences as to how things might vary in terms of general management and available packages. I'm talking more about core concepts. So as an example, I would like to understand the inner workings for a use-case such as:

1) multi-WAN set up with load-balancing and sticky sessions
2) site-to-site VPN layered over top of multi-WAN
3) for that VPN, assign a preference for the higher speed WAN link

Appreciate any input. Thx.
