[SQU] Squid time out problem?

Dear friends,

        I found a problem with my squid 2.3Stable1 proxy.
My Web access to USA sites (from machines with masquerade IPs)
return with message:

"The requested URL could not be retrieved"
...Unable to determine IP address from host name for ...

        The Web access to USA sites of machine with squid
is OK (with 10 seconds more or less). I'm using the
ipchains *redirect* of 80 port to squid port in all
hosts of my site.

        Brazil sites requests is OK. I'm needing of
very help. There are a solution???

Best Regards,

               Denis
