Sony PS3 can't see Serviio on iMac

I have Serviio set up on my iMac. My router is a Linksys e3000. I have a static IP of 192.168.1.107 assigned to my iMac with TCP 8895 and UDP 1900 forwarded to it. I upgraded to Serviio 1.4 and my OS to Mavericks. Now my PS3 can't see Serviio. I have the same problem on Windows (dual boot via Bootcamp) as well. All ports look fine and my PS3 still can't see the server (yes I changed the forwarded IP on the Windows side). I tried putting my PS3 in a DMZ and that didn't work either. Does anyone have any ideas? What am I doing wrong?
