forward all HTTP requests to the proxy

hi

howto redirect the whole HTTP traffic using proxy ?

I have tried using iptables:

Code:

iptables -t nat -A PREROUTING -p tcp --dport 80 -j DNAT --to-destination 192.168.0.3:3128

but it doesn't work !

this machine is a vpn gateway and should redirect the whole HTTP traffic to the proxy.

p.s
but I'm not using a transparent proxy.

greetings
cccc

the command there looks broadly correct, but you've said nothing useful about your setup. you say you are not using a transparent proxy? well that command IS a transparent proxy...

all i can say is that normally you'd either also specify a source address range or an incoming interface in addition to what you have there. probably useful to see what tcpdump says about what port 80 thrughput is doing.

according to tcpdump is not asking the proxy:

Code:

#tcpdump: listening on eth0
