I guess that you would need to use third party software installed on a PC to get Remote Play on the Wireguard VPN, as I have seen on the Internet about this.
i analyzed gta online traffic on the playstation and figured out its just like pc with other words if you make playstation.net as bypass you won't leak it in games, since traffic does not use playstations api to communicate with p2p peers.
Only issue is maybe with playstations direct communications like microphone chat, i haven't checked this.
You can use something like this: tcpdump -i br-lan host ps5host
I want to try and stick to domain policies as I am already using that for things like accessing the FQDN of my NAS and not going through the VPN. This works perfectly fine.
Got it, it seems that a multiplex policy based on domain and mac together would be help in such scenario. I think we shall try to make it in the future.
Back to this issue, I asked the chatgpt and it told me these domains, maybe you can give it a try?
