[K12OSN] DHCP

[gKw-X]

The proxy is a redhat server, and I have root access to it. I'm not the 
one that configured it so I'm not sure what his reasoning was for 
setting it up the way it is, but transparent proxy sounds like it would 
be good... They have a lot of problems because of proxy settings, they 
always think the internet doesn't work when it's just that the browser 
settings were wrong...

Is it very difficult to set up transparent proxy? Anyone have a link 
handy that explains it? I found one and it talks about recompiling the 
kernel... I don't think I want to get into that.
