Re: redirect all ports to squid

    Hi,

    
    Yes, we can redirect the ports to squid through our firewall rules.

    
    Check below lines to redirect the ports.

    We have some different methods to do.

    1. In first Method:

        First, we need to machine that squid will be running on, You do
    not need iptables or any special kernel options on this machine,
    just squid. You *will*, however, need the 'http_accel' options as
    described above.

    
        You'll want to use the following set of commands on
    iptables-box:
    
      iptables -t nat -A PREROUTING -i eth0 -s ! squid-box
        -p tcp --dport 80 -j DNAT --to squid-box:3128
      iptables -t nat -A POSTROUTING -o eth0 -s local-network
        -d squid-box -j SNAT --to iptables-box
      iptables -A FORWARD -s local-network -d squid-box
        -i eth0 -o eth0 -p tcp --dport 3128 -j ACCEPT
    
    2. And have another method:

    
      iptables -t mangle -A PREROUTING -j ACCEPT -p tcp --dport 80
        -s squid-box
      iptables -t mangle -A PREROUTING -j MARK --set-mark 3 -p tcp
        --dport 80
      ip rule add fwmark 3 table 2
      ip route add default via squid-box dev eth1 table 2
    
            (OR)
        iptables -A PREROUTING -t nat -i eth0 -p tcp --dport 80 -j
      REDIRECT --to-port 3128
    Regards,

      It's possible to redirect all ports to squid ? thru iptables ?
For example port 25 smtp,143 imap, etc...
Can squid handle that. In transparent mode.
