So I am currently developing a custom dedicated server in UE4 from scratch. I use RakNet as a networking engine and want to achieve the typical dedicated server that can manage adding players to the world, hitboxes, collision and verifying packets in general. What I mean by verifying here is e.g. if the server receives a movement packet it can decide whether the packet's sender can move there or not. I see the biggest trouble in verifying the e.g. movement packets and hitboxes because the server has to have access to the world and collision methods of unreal which I don't know how to do from scratch. Is it possible to get the base server from UE4 and equip it with your own networking engine and packet handling? Or is there a better way to achieve my goal?

You realize UE has its full source public right? You can just download the full source code and change anything you like in it, so the answer is yes!

I know that the source is public but I am lacking orientation in the UE4 code. So the server should e.g. not render anything because that is unnecessary for doing hitboxes calculations. Correct me if I am wrong.

AFAIK there is no out of the box solution for that. You need something custom. I can think of 3 solutions:
Just ignore collisions. Replicate what you get from clients, and that's it. Of course this is a cheap, low effort solution prone to hacking, but maybe it's sufficient for your case ?
Write custom collision handling on your server. This is a lot of work. Server would need to know all the colliders positions, dimensions, etc. You could then use a physics library ( i.e. Bullet Physics ) to check collisions or write a custom collision checks.
Compile UE4 as a dedicated server. You can find more info here:
https://wiki.unrealengine.com/Dedicated_Server_Guide_(Windows_%26_Linux)
Just use Raknet instead of a native UE4 networking.
PS. UE4 source code is over 2 milion lines of sophisticated C++ code so telling someone to "just download the source code and change anything you like" is not a viable advice.
PS.PS. I'm not sure if RakNet is a good choice at the present moment, this project was not updated since 5 years.
