[ale] network question with a little linux

[Mark Walters]

Thanks Bob and DragOn,
I setup a linux router yesterday and I'm in the process of putting my 
wireless router behind that. I think this will be the most secure solution 
and one that works, provided I secure it properly. :-> Thanks for the 
help.
