I've got a RPI4 w/4gb setup with a direct cat6 to the streaming PC, but Wifi to the internet. I'd like to bind Steamlink to only use eth0 and avoid using wlan0 for its connection. Is there a way to tell Steamlink to use a specific interface for streaming?

Worst case I can use iptables to try to block the desktop, but wanted to avoid introducing the firewall into the mix.
