If you have a home router, you will have to do a portscan to see what ports bryce lighting uses. Then, find out how to configure your router (should be 192.168.0.1, just type that into explorer. The username is admin and there should be no password.) You then need to setup a port redirect or else bryce lighting will only see the local network. So, set the local ip to whatever your computer is. Then set the local and public ports to the same thing. (on a mac, bryce lighting is port 8000) This tells the router to scan public IP's for the port 8000 channel instead of just the local LAN connection. See the image for a snqapshot of my touter's config. The madmax thing is the one redirecting to bryce lighting.
