reverse router's Firmware (to decrypt config)

[essential]

hi everybpdy,
i got this problem:
i can't understand which encryption a router's config file has got.

The router is a D-Link DI-524 Airplus G
i tried to view the binary file...as far as i can see, it might not be compressed, maybe just encrypted

i already tried using some tools, but without any good result.
so i'm guessing the olny way left would be reversing the Firmware (to find the routines that read and write the config.bin)
The firmware is most probably written in C and compiled onto a MIPS or ARM processor...since i'm no good at reversing, i need your help!

Here's the config.bin

here's the firmware (version V2.04 dated 28 april 2006)

ftp://ftp.dlink.co.uk/di_broadband_gateways/di-524/
i also found a source-code of firmware (though i'm NOT sure it's exactly the same as mine V2.04...)

thanks a lot
