Using the networking system with a dedicated server

I want to use UE4’s networking and Actor Replication system, but with a dedicated server (not running UE).

The idea is that I don’t need the physics, nor any of the big precision UE brings, so I want to build a simple server that would communicate with my client through sockets.

The only think I don’t know is if it is possible to take advantage of the synchronization mechanics of the networking features if we are not using UE’s Dedicated Server. Like, if I make my own server, is there some sort of way that I can interface to networking features so I can for example send the players positions to clients, and they will be correctly interpolated by the engine and so on?
