LARTC - Jun 2004 - fairnat with squid + Squid with ZPH

Hi,

I''m trying to share internet on a LAN
I''ve a linux router with SQUID (with ZPH support) + FAIRNAT

The idea is:

- fairness sharing internet
- priorize interactive traffic
- if a web object is on squid-cache (HIT), user
  can download it, with a rate = LAN rate

I''ve:

- Last Fairnat Script: www.metamorpher.de/fairnat/
- SQUID 2.5STABLE5 with ZPH patch http://www.it-academy.bg/zph/
- pached kernel with:
	- netfilter connmark patch
	- netfilter ttl patch
	- htb "HYSTERISYS =0"
	- "sfq DEPTH = 16"
	- "PSCHED CPU"
	- and last HTB patch.


and...

modified fairnat script with:
