[Macpartners] mapping ports on http requests

[Mark Klein]

Thanks for the ideas. I tried the ssh trick too, couldn't make it  
work. The problem is that I'm not an IT guy, and don't have experience  
with all these features, so I need detailed instructions, or else  
someone willing to make the changes for me.
