Dang thanks for this, I have vlans and use opnsense but I couldn't figure out how to connect to the printer from bambu studio. Ive installed the udpbroadcastrelay plugin on opnsense but it still doesn't seem to connect. Do you mind posting a screenshot of your pfsense config?
Thanks for posting this!
What's the latest firmware version that shittifies these printers? I have an a1 mini with version 1.4
