Congrats on getting it worked out!

I am at a loss, wish I could be of more help.

Ignore what I had before, just saw that you've already checked your public IP. I don't know why ubooquity would think it's something else. Jason may be right, it does look as though there is a space in your port number.

Match up your router here: http://portforward.com/english/routers/port_forwarding/Asus/

I've never had a Asus router, but that site has been very helpful whenever I try and get it set up with my previous Linksys router and now my Netgear router.

This is odd, I don't normally use Macs so I borrowed one and set up Ubooquity. It didn't ask for any permissions in OSX in relation to the firewall. All had I to do was redirect outside traffic from my normal plex/ubooquity server to the Mac and it was working immediately.

Do you have port-forwarding set up on your router?

Has anyone tried custom fonts?
