I want to be able to switch between playing Destiny 2 on my PC and Xbox, especially with cross-save coming but based on the official networking recommendations I don't see how that's possible. The official firewall info at https://www.bungie.net/en/Help/Troubleshoot?oid=13610 indicates that for Xbox you are supposed to forward ports TCP 3074 and UDP 88, 500, 1200, [b]3074[/b], 3544, 4500. However that same guide also indicates that for PC you are to forward UDP [b]3074[/b], 3097. How are you supposed to forward UDP 3074 to two different destinations? Is TCP 3074 meant to be a fallback if UDP 3074 doesn't work? If that's the case should I just forward TCP 3074 to my Xbox and UDP 3074 to my PC? By definition (at least as I understand it) port forwarding takes all incoming traffic on a given port and sends it to a specific internal IP. It's not possible to send all incoming traffic on a given port to two different internal IPs and maintain the same port number. Furthermore without port forwarding you can't just open the port if communication on that port is initiated from the internet, likely why Bungie wants you to forward that port. The firewall/router has no idea what internal client to send that traffic to if communication isn't initiated from a LAN client, hence the value of port forwarding. UPnP is not the answer; that's a big security risk and Bungie should know better than to tell people to rely on it. So based on that how in the world are you ever supposed to have a PC and Xbox client on the same network and both be able to play?
