I’d recommend something like a split tunnel then. And I’m only saying that because I’m not well-versed in networking like this, especially when containers are involved.

But I do have containers routing their traffic through a VPN via gluetun, and it’s worked flawlessly.

I think I’m missing something…why bother with SOCKS5 if you’re using a gluetun container? I’ve never done what you’re trying to do, but I’d assume gluten by itself is the solution
