Hi everybody,
i apologize for being quite a newbie (but willing to learn!)
Well, my problem is a decryption (or also decompression?) problem.
It's all about the config file of a D-Link DI-524, firmware version V2.04 april 28 2006.

The file is called "config.bin".
First i've been trying to understand which type of file is the .BIN i'm dealing with:
i would bet it's an encrypted (maybe compressed too) .XML file ...but i didn't understand which algorithm locks it.

I'm not able to reverse engineer the firmware to discover the routines and algorithm the router uses to write/read the config file.
I found a couple of tools (around on the net), which decompress/decrypt some .bin files and they are useful for the specific router they are developed for (Zyxel, Linksys, Cisco...) but, as expected, they do not work on my D-Link config file.
I also checked out this app called DOCSIS http://docsis.sourceforge.net/ but it seem to work only on cable modem...
Can you please help me?

here's the config.bin
