I was told differently on this list.  The Edubuntu Wiki suggests that it 
is a solution.  If it is in fact deprecated, and I believe you, then we 
really need to get on the same page of what *does* work with 7.10.

I definitely need to echo that making changes to /etc/sysctl.conf *do* 
*not* have any affect on ip_forwarding.  It is annoying, it does not 
make sense, but I thought that it was just me.  I enable ip_forwarding 
through a line in rc.local.
