This is a DGL-4500 router?
First, I was wrong about DYNDNS. The DGL-4500 has a DYNDNS page that will connect back to DYNDNS, so if your IP changes it will change accordingly. Pretty cool. But lets not play with this now, just use the ip address returned from whatismyip.
Lets get the port forwarding to work.
First, you don't need UDP. You don't need port 443 (SSL). All you need is port 80, TCP. That is what http runs as.
Second, are you editting the screen for Advanced/Virtual Server? That is the one you need to Port Forward (this manual is crap, it mentions Port Forward but the function isn't named port forward.)
Okay, that one should be:
Enable (check)
Name (your choice)
IP Address (192.168.0.136)
Protocol TCP
Private port 80
public port 80
schedule always
inbound filter allow all
The public port is how you might get around your ISP hosting restrictions. So the default for http/web is 80.
If we pick a number, say 8000, if we change the public port to 8000 (we don't have to change the web server, it stays at 80, your router will "forward" the connection from the internet at port 8000 to port 80 internally) but now the URL would be:
(the :XXXX is for the port number)
But lets see if it works with 80 first, so you don't need the :XXXX
if you added rules elsewhere, they are wrong (access control or filtering).
