[K12OSN] transparent proxying with LTSP

[Brad Johnson]

Greetings everyone,

I am in the final stages of completing our first large LTSP lab.  In the 
past, I have been setting the proxy settings inside Firefox, but would 
prefer to do this transparently.  Does anyone have any experience doing 
this with ipchains, or any GUI-based firewalls?  What is your advice? 
I'd also prefer to redirect to an existing squid/dansguardian proxy that 
I already have, but I can live with setting up an additional proxy if I 
have to.

Thanks,

Brad
