Implementation of transparent proxy

Basic implementation

1. Modify squid. conf

Http_port 192.168.0.100: 3128Transparent

2. Reload the configuration file

3. Add iptables rules to redirect internal HTTP requests to port 3128

Iptables-T Nat-A prerouting-I eth0-s 192.168.0.0/24-P TCP -- dport 80-J redirect -- To 3128

(Redirect port 80 requests from 192.168.0.0/24 to port 3128)

Enter 200.168.0.109 on the PC for testing.
