I mean from any other machine?
Your interception rule in iptables only applies to traffic forwarded, 
not traffic originating from the box itself.


Thanks a lot Henrik, it is working now. But it is slow. The page gets
loaded in say 30 secs instead of usual 8-10 secs.
What must be the problem with this? Is it dnsserver problem? I have made
no changes to that sectin at all. Also, I have my own name server on the
Linux (squid) box.
With warm regards,

Hi Payal,

If its a DNS problem you should take a look at the Cache Manager in 
general runtime information there is a section called ¨Median Service 
Times¨ if your DNS lookups are taking a long time you should see it here 
, for example below:

Median Service Times (seconds)  5 min    60 min:
    HTTP Requests (All):   0.02317  0.02899
    Cache Misses:          0.28853  0.25890
    Cache Hits:            0.00379  0.00379
    Near Hits:             0.24524  0.18699
    Not-Modified Replies:  0.00286  0.00379
    DNS Lookups:           0.00094  0.00094
    ICP Queries:           0.00085  0.00096
In some cases we have seen the DNS lookups @ 1.00032 or something like 
that and its usually been a local problem with named, either way the 
cache manager might be able to give you some other informaton that will 
help you find where your problem is, ive found it very usefull at times.

Hope this helps.

Richard
