go-pcap2socks functions like a router, allowing you to connect various devices such as an XBOX, PlayStation (PS4, PS5), Nintendo Switch, mobile phones, printers and others to any SOCKS5 proxy server. Additionally, you can host a SOCKS5 proxy server on the same PC to use services like a VPN or a game booster/accelerator for reduced latency
It works on L2 OSI model, and can't not support something, please show config file and screenshot from network settings in nintendo switch (where you enter ip, dns etc)
Do you have a Switch that can do the test?
