From what I have found out, it seems that your modem does not have a built in firewall but your router has. This is what D-Link says about it: So, I suggest that you first download a userguide and read up on your equipment, here is the URL:

D-Link DI-524 High Speed 2.4GHz (802.11g) Wireless Router

Finally, I could not find anything that could help you configure your router on the "Port Forwarding" site other than "PFConfig" an automated port forwarding utility which you may have to buy, here is the URL:

https://portforward.com/store/pfconfig.cgi

However, check out the site because something could be there that may help you:

Did LW ever work well with Java 1.6.0_02 installed? That version works fine for me but some people have had problems with it. You could try this older version of Java & see whether that makes any difference. Use the JRE offline installer & remove your current Java version before you install this one.

It wouldn't hurt to delete LW's preferences folder when LW's properly closed. See point 3 here & also point 2 if you've used older versions of LW in the past (there could be a folder in either location).

This will kill all of your settings within options, you'll have to go back through afterwards & reset things. If you're not sure of your settings, go through LW's tools > options & write them all down, so that you can reset things later.

These instructions should help you to set up port forwarding.
Port Forwarding for the Dlink DI-524
As LOTR said before, don't forget the step of setting up a static IP first LW's listening port, port in the 'manual port forward' box & port forwarded within the router all have to be the same number.

This will explain a bit more about a static IP address
