Ok so i hacked up nat so that it would compile on jaguar (os x 10.2) and i have it available for download here
i want to add it to the fink tree but i'm not sure where to start... the online docs didn't help me during the 10 mintues i looked at them... for now you can grab it off my site here. but
somday i'll figure out the right way to put it in fink...
oh well =]
