DusselMauser 0 Posted March 17 Hello. So, I've been trying to host for friends for a while now but ever since I changed providers I've been limited to using hamachi and it's very awful ping to host, which has been grueling. Even after enabling UPNP, disabling it, opening the ports 2302-2306 UDP, and even testing to see the ports were open using a port tool (and getting confirmation they are infact open,) I get this same message "Port forwarding setup failed." When checking what ports arma tries to use, it doesn't seem to even try to use any of these ports, and instead goes for a port that seems to be completely random each time, though even with the ports in this range of random opened, I still get that same error. Turning off firewall and adding the ports as inbound outbound rules also produced no results. I checked to see if my new ISP was using Carrier Grade NAT, and that is also not the problem.
