maybe problem is from ebox firewall or someting..
i don,t know  how to redirect port 80 to ebox proxy port...

many thanks for help...

Hello Longthorn,
  if you want to use the  transparent proxy option you must have eBox as gateway. In this mode eBox takes care itself for the redirections so you don have to do anything special.

Don hesitate to ask more questions if this message doesn help you

make sure you have configured a DNS server for eBox itself.

Go to Network->DNS to check if you have any. If you have enabled the eBox DNS server you can introduce 127.0.0.1 or any other external DNS server.

[lonthong2002]

sure.... i already config dns....the problem is only if use proxy....because if proxy disable ..everything is ok...

Ok then, let's use the diagnosis tool

Go to Network->diagnosis and try to look up a domain, and ping it.

sorry , i think  is not from dns problem...
because if proxy disable ... everything is normal....

only enable and disable http proxy...no change with dns or firewall setting..
......

[javi]

Ok, it seems it's not a DNS problem then.

What's your global policy in proxy settings? Select 'always accept' and make sure you don't have any object with filter policy, save changes and try again

[lonthong2002]

Select 'always accept' and make sure you don't have any object with filter policy, save changes and try again<<< sure ... i do that....

but still got problem... proxy not working...
i check with ssh to ebox with command tail-f /var/log/squid/acces.log<<<<<no cache ((
