Yes that is true that i should give more information so:
this is from client inside LAN:
Non-authoritative answer:
Name:   google.com
Address: 64.233.187.99
Name:   google.com
Address: 72.14.207.99
Name:   google.com
Address: 64.233.167.99

Yes, clients can ping google IPs.

When i try connect by telnet i have smth like this.

telnet 64.233.167.99 80
Trying 64.233.167.99...
Connected to 64.233.167.99.
Escape character is '^]'.
GET / HTTP/1.0
Host: google.com


Connection closed by foreign host.

There is nothing happening after pressing enter couple times the connection
is closing by foreigh host.

I have tested 3 IP that indicates google.com domain and it is the same every
time.

What is wrong with this ?
