Dear Matt and All
        Actually i just realized that telnet is also not working ... only ssh is working from the internet.... I am really sorry for the wrong information... I have tried everything possible after searching the internet but not able to find any solution.... I dont know why simple telnet is not working over the internet when all the security if turned off... my telnet config file looks like:

[root@ecgrid ~]# cat /etc/xinetd.d/telnet
# default: on
# description: The telnet server serves telnet sessions; it uses \
#       unencrypted username/password pairs for authentication.
service telnet
{
        flags           = REUSE
        socket_type     = stream
        wait            = no
        user            = root
        server          = /usr/sbin/in.telnetd
        log_on_failure += USERID
        disable         = no
}

I CANNOT TELNET FROM THE INTERNET BUT I CAN TELNET THE WEB SERVER FROM THE SAME COMPUTER.... AND THIS IS WHAT I GET ....

[root@ecgrid ~]# telnet 133.xx.xx.xxx 80
Trying 133.xx.xx.xxx...

[root@ecgrid ~]#

ERROR LOG: there is not entry in the error log for an access attempt from the internet....

I am using the IP address of my web server instead of its FQDN ...

I am trying to solve the problem with the telnet before coming back to apache... in case you have any idea please let me know....

Thanks
Asim

You say you have an internet Static IP, does that mean you are running
on a modem with a software firewall and that you really DO have a static
IP, or do you use a firewall router on which you have setup port
forwarding for port 80. That is does your NIC bind to the public IP, or
does it bind to a static LAN IP which you have forwarded port 80 from
outside?

If you can telnet to apache from the internet then apache is answering
on the LAN _and_ internet NICs then you are almost there

If you used the following _from the internet_ and received the homepage
then all is well with the apache setup
telnet your_internet_IP 80
GET / HTTP/1.1
User-Agent: firefox
Host: yourservers_fully_qualified_domain_name
[enter][enter]

However if when you do this, you get a default page of some kind, maybe
even an error then apache needs setting up to serve that FQDN, perhaps
you need a servername directive in the vhosts section if you are serving
more than one site.

If you get nothing, "host not found", then you need to add a public A
record for that FQDN pointing at your internet IP.

So more details about the error are needed, what does the apache error
log say, what is the error you get when trying from the internet? Have
you set up a public DNS record, or can you add a hosts entry on the
machine you are connecting FROM
YOUR_PUBLIC_IP fully_qualified_domain_name
so that even without DNS you know that your servername is matched to the
correct IP address for that machine.

Rather than have us suggest an endless stream of options, why not give
us a bit more info?
