I found this old thread ( LINK) - this is exactly the issue I am having. I can not access the Yun at http://linino.local - I am on Win 10 and added the rule to the Firewall for port 5353 , UDP.
Did a restart - still no luck.
Still - I will need to open this port on any device I want to access the Yun from? This does not seem to practical, or am I missing something?
