B. I'm kind of confused about what you are trying to do as what you
describe kind of looks like I'd expect. The DNS lookup and the tracert
give correct looking info

Perhaps you can give us some more information about what you are trying
to do.

I'm guessing that you are trying to access the Slimserver using the
external proxy address. Tracert will not show you a hop to the
Slimserver as it is stopping, as it is told to, at your router. With
port forwarding you can effectively consider that you are setting up
two connections, one to the router and then the router sets up one to
the Server. It then joins both bits together.

So if you are, for example, trying to get to the slimserver web port at
Slimserver:9000 then internally you would be using something like
192.168.1.2:9000 Your source and server would then communicate
directly.

To use the DNS name your router would have to have had port forwarding
set up for port 9000 to route to internal IP 192.168.1.2:9000 that way
a request to myhost.dyndns.org:9000 would get you the slimserver.
(myhost being the name you registered with dyndns.)

If you are just trying myhost.dnydns.org from a web browser you will be
incoming to the router on port 80 which probably doesn't do anything (it
may give you your router admin pages depending upon it's setup). You
could chose to forward port 80 but that isn't such a good idea. 

The other possibility is that you have port 9000 forwarded but haven't
specified it should be forwarded to port 9000 on the server. In which
case I'd guess what happens is undefined. If there isn't the option to
specify the port to forward to then it is likely just using the same
port number as inbound. If it can be specified then it may be trying to
go to port 80 (as it is the default HTTP port). Again this won't do
anything.

Having said all that it may still not work depending upon how clever
the router is. Since the response from the server would be going to an
'apparent' external WAN address the router may be applying it's port
forwarding rules looking for a way to get back to the 'internal'
source.
