Infuse 3 blocked by my firewall

After upgrade to Yosemite, couldn’t connect to my shares. On the app, I went to available shares, and my iMac was there. Naturally I logged in as normal, saved it , and it timed out. It would never connect, even after deleting that share and repeating the process. So I went to my iMac, disabled the firewall, and instantly connected to my files. As soon as I turn on the firewall, blocked again.
So how can I fix this?
