I've purchased rFactor 2 yesterday to drive with a friend. We have had a succesfull GSCE server running so i figured this would be fairly similar to set up. After some looking around (this forum could use a sticky) and finding dozens of ports i should forward i finally found the 2 ports, and that the game went from a ini to a JSON. So i've forwarded everything and disabled the windows firewall alltogether and finally got my server showing and joinable. Clients can download the mods (only standard stuff) and everything seems to be working. When another player joins he can race the AI without a problem. However when i join i can drive like normal, however other players and the AI don't see me. i have no influence on the physics of any other cars. This means i can just drive in front of an AI and he literally just plows through me. He will drive on without anything changing while i go flying. Same goes for other players. They do not see me and if i hit them nothing happens on their client. I have looked around for a while and saw a post somewhere where players thought it could be the server couldnt handle it. So i put the server on a seperate pc (a gaming rig, so a beefy pc) and reforwarded the ports again to run into the exact same problem. Like i said i have rebound the ports to different ports in the multiplayer.JSON file, and forwarded those but that doesnt change anything. To see if it might have been windows firewall i completely disabled that on both the server and client to test it as well, but no changes whatsoever. I don't know where to look anymore. I've tried the prototype server and the regular server. Both have the same problem. It seems i do not send packets to my local server. However as far as i know i can't join it using a local ip, and i have no idea what else the problem could be. Any ideas? I don't know what else to try anymore after 6 hours of tinkering.
