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,
Visolve Squid

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.
