Ok, I checked the post and it’s very helpful it is isolated to the UDP Messaging Plugin, after making the change in the UDP plugin file that stopped the traffic from being sent out from the editor and bouncing like discovery service to the other devices on the network and the bandwidth flooding stopped and all devices on the network are fully responsive now with normal speed test results.
I came across a few search results online about some older Unreal Engine network security issues and one related to the Google UDP Cryptographic Analysis Vulnerability Scanning and Unreal Engine 3, and result saying people recommend "blocking all UDP traffic to any device that has port 7777 enabled via the router."
The problem is I am working on a multiplayer game for the long term and experimenting with some smaller multiplayer projects and so this will require the editor and services being enabled to work properly if I am correct, correct me if I’m wrong?
Atleast we know it is isolated to the UDP plugin and via the UDP traffic, even if I set the port forwarding to isolate the service, I would assume it would still cause problems for clients connecting remotely to local service end points and possibly cause lag over the network, I do not know what the effect would be outside the network on third party routers and networks, it may produce similar results on their end as well lowering network performance of the clients, that would impact multiplayer game performance as well possibly giving a jittery network experience, I hope not.
