Hello,
Firstly, I'm not an expert in iptables or squid...I just use both on a
regular basis. :)
From my readings of the Squid man pages and other online resources, I
am led to believe that not all protocols are capable of being handled by
redirecting the destination ports (21, 443, etc.) to squid-proxy's
listening port (3128). I believe this method is called transparent proxying.
I'm quite confident that Squid can't transparently proxy FTP and SSL
protocols....however, I'm not sure about what other protocols could be
tranparently proxied (I only transparently proxy port 80 for myself).

helloo everyone finally im controlling all the input and output traffic on
my network
now i would like to control the traffic and internet /intranet access via
squid
example
10.30.143.1-internal network
10.30.142.1/server-gateway-and-iptables-firewall
10.x.x.x-external network
how can i redirect all the packets/ports to squid ? or at least control
the bandwith using iptables
Make 10.30.142.1 the gateway for all the PCs in the internal network.
Then on the gateway, use iptables and redirect all ports to the port
squid listens to.
eg : to redirect port 80 traffic to squid's 3128 :
iptables -t nat -A PREROUTING -i eth0 -p tcp --dport 80 -j REDIRECT
--to-port 3128
Ace.
