Squid on OpenVZ CentsOs container [message #39559]

Hello,

A friend a has setup my first OpenVZ server on CentOS 5.4
One container is created using centos-5 template.
I then installed squid in the VM.

My ifconfig looks like this:

[root@vps-101-gw-LL ~]# ifconfig
lo        Link encap:Local Loopback
          inet addr:127.0.0.1  Mask:255.0.0.0
          inet6 addr: ::1/128 Scope:Host
          UP LOOPBACK RUNNING  MTU:16436  Metric:1
          RX packets:25 errors:0 dropped:0 overruns:0 frame:0
          TX packets:25 errors:0 dropped:0 overruns:0 carrier:0

          RX bytes:1364 (1.3 KiB)  TX bytes:1364 (1.3 KiB)

venet0    Link encap:UNSPEC  HWaddr 00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00
          inet addr:127.0.0.1  P-t-P:127.0.0.1  Bcast:0.0.0.0  Mask:255.255.255.255
          UP BROADCAST POINTOPOINT RUNNING NOARP  MTU:1500  Metric:1
          RX packets:226 errors:0 dropped:0 overruns:0 frame:0
          TX packets:229 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:0
          RX bytes:20076 (19.6 KiB)  TX bytes:41658 (40.6 KiB)

venet0:0  Link encap:UNSPEC  HWaddr 00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00
          inet addr:192.168.1.23  P-t-P:192.168.1.23  Bcast:192.168.1.23  Mask:255.255.255.255
          UP BROADCAST POINTOPOINT RUNNING NOARP  MTU:1500  Metric:1

I have added the following 2 lines in my rc.local:

echo 1 > /proc/sys/net/ipv4/ip_forward
iptables -t nat -A PREROUTING -i venet0 -p tcp --dport 80 -j REDIRECT --to-port 8080

The problem is here:
When a client PC's browser tries to access any website, I get "PAGE CANNOT BE DISPLAYED" error. Requests do not reach squid.

If I setup proxy setting in the browser as 192.168.1.23:80 then the requests reach squid and the pages are served well.

I am unable to understand why should I have to define PROXY settings in browser. Standard browser requests are sent to port 80 anyways, which should reach squid.

Note: in browser's proxy setting, the PORT is set to 80. Not 3128.

Any pointers or ideas are appreciated.

Thx
Sans

After reading various posts & how-to I am now beginning to give up.

Can anyone help me with the network settings to setup squid on openvz. The squid part is done and working.

I am unable to get the network configuration.

Thx in advance.

Best regards,
San
