[squid-users] redirect all ports to squid

[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
