[squid-users] Transparent proxy with multiple protocols

I have squid running as a transparent accelerated cache proxy. I'm
wondering if I can use this same instance of squid to proxy https and ftp as
well as http (forget gopher and wais). The main reason why we're running
squid is for access control (using squidGuard). I'd like to be able to
filter ftp and https, too.

I assumed I could do:

iptables -t nat -A PREROUTING -p TCP --dport 20 -j REDIRECT --to-port 3128
iptables -t nat -A PREROUTING -p TCP --dport 21 -j REDIRECT --to-port 3128
iptables -t nat -A PREROUTING -p TCP --dport 80 -j REDIRECT --to-port 3128
iptables -t nat -A PREROUTING -p TCP --dport 443 -j REDIRECT --to-port 3128

then configure squid.conf with:

httpd_accel_port 0
or
httpd_accel_port 20 21 80 443

But I haven't had any luck. If somebody can tell me how to configure it for
this, I'd be a very happy person. :)

Thanks,

Nate
