Re: [CentOS] Unable to configure squid transparent proxy on Centos4.0

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]



 I am trying to configure Squid Transparent Proxy on Centos4.0. The eth0 is
connected to the Internet and eth1 is for the LAN connection
I am testing this scenario with 2 machines one machine (Centos4.0 ) on which
squid is running and other machine which is debian is on the network
192.168.2.0 .

Centos4.0
   eth0:   192.168.1.125/24
   eth1:   192.168.2.126/24

Debian:
   eth0:  192.168.2.83/24  gateway: 192.168.2.126/24 (eth1 of Centos)

Squid works fine if I manually add the proxy settings in any browser for the
clients of network ( 192.168.1.0) but as I want to configure transparent
proxy I have added these lines to squid.conf
          http_port 5678
          httpd_accel_host virtual
          httpd_accel_port 80
          httpd_accel_with_proxy on
          httpd_accel_uses_host_header on

iptables configuration  Only one rule is there

iptables -t nat -A PREROUTING -p tcp --dport 80 -j REDIRECT --to-port 5678

Any pointers what can be the problem ?
The only difference i can see with my configuration is

iptables -A PREROUTING -t nat -s 10.1.1.0/24 -i eth1 -p tcp --dport 80
-j REDIRECT --to-port 3128
as you can see i have the -s option enabled, i just wonder if you are
creating a loop and making squid to go back to himself when "he" wants
to go for the webpage?

regards,

Guillermo.
