actually since you set up the port forwarding manually, just the bottom should be checked. I am afraid that I can't help you set up a DynDNS account since I have only done it once and I don't remember how I did it. You should be able to look online for a good guide though. There is one here that I used:

but I'm not sure how up to date it is anymore.
1. Try just unchecking that top part and seeing if entering
http://richard.subsonic.org:85/ in to the android client works.
2. If it doesn't try following the guide I gave you.
3. If that doesn't work, search online for a better guide.
