Forza horizon 5

[japivee]

Have anybody been able to play two instances of Forza Horizon 5 with Aster? I was able to launch two Steams after I updated the Aster, and I can launch two Forza Horizon 5 games now that I have installed them to two locations. However, I cannot get both instances to online (Horizon Life) at the same time. Both game clients can get individually to online, but not when the other client is already online. I tried to tackle this issue by setting static IP addresses to my wifi network adapter and ethernet network adapter, and then assigning these IPs to the workplaces. Both workspaces have access to internet, and there are strong implications that it happens through the specified network adapter, since if I turn off the wifi, the other workspace has no longer acces to the internet. Nonetheless, I cannot go online on both clients simultaneously, I get an error message that reads "unable to join session" Is it possible that Forza still binds to the same adapter? I also wonder why changing the clientport on Steam launch options didn't help. Now that they have different IP:s and MAC:s I can't figure out why it is not working. Maybe I should have Steam installed on separate locations as well as the game?

Any help or thought would be welcome. Thanks in advance!

Edit: We have two legitimately bought Steam copies of the game.

Even with separate IPs and MACs, Xbox Live likely sees both games as coming from the same machine/network, causing conflicts.

1. Change interface priority (via adapter metrics).
2. Use a VPN or mobile hotspot on one workspace to isolate network traffic.
3. Install separate Steam instances for each workspace.
4. Use port forwarding or firewall rules to bind services to specific IPs.

Let me know if you want help with any of these steps.
