Sorry for crossposting into another subforum, but I think this needs to be seen! I did some analysis regarding permament network-issues when playing Destiny 2. Even if Destination NAT (aka Port Forwarding) and Firewall Settings (L3,4, IPS) were done properly, I was facing a lot of disconnects, lags and some general weird network related issues. Yesterday evening I found the root cause of this problem. Bungie Servers are not only talking with their public IP, but also with private IP´s with the PS4. I guess there´s some unencrypted Tunnel established, therefore the private IP´s are visible. Bungie Hosts belong to Network-Ranges like 192.168.0.x, 192.168.2.x. The problem is, that a lot of home-networks are using these networks - so we are facing routing issues due to overlapping networks. In my case I added a policy route to always use the WAN gateway for outgoing connections from PS4, but users with 'normal' equipment can´t workaround that easily. They would have to change the internal network-range in order to get Destiny to work correctly. Bungie, please change the network communication behaviour. Either use public IP´s, or in case of tunneled traffic, use uncommon private network-ranges so that users won´t experience such issues.
