NAT type error
Hey. I'm from Iran and I'm getting nat type error each time. It happens randomly but the chance to get the error is something like 80%. Also, I asked about 7 friends (they're all from Iran aswell) and they are all facing the same problem. I'm assuming Russia and Pakistan are facing the same problem (saying this because there was some speculation that we get this error because of sanctions). The only way to solve it is to use vpn but vpn costs alot and it also ruins our ping. I tried port-forwarding, changing DMZ, UPnP, switching NAT, changing dns but non of them worked. I'm also assuming this is dbd's problem, not our problem because I (and my friends) can play other multiplayer games without any problem. We really like dbd but we really can't play it with this problem, I'd appreciate any dev/cm responding and noticing this problem so much.
