Unable to Access Apache from Local Network

[Kumaradevan]

I have installed XAMPP 1.6.6 on RHEL V 5. This is my first experience with XAMPP and Linux.
After running /opt/lampp/lampp start, I am able to access the XAMPP homepage through http://localhost and http://<server-ip> locally from the server.
But I am not successful in accessing the homepage from any other computer in the Local Area Network by giving http://<server-ip>. Internet Explorer says it cannot display the page.

I am able to ping the Server on the local network. I have used a Static IP for the Server.

I have tried the following:
1. Editing /opt/lampp/etc/httpd.conf and added the IP Address in the Server Directive
2. Apache is listening on the standard port 80
3. I have tried disabling SELinux totally

Can someone help?

Thanks in advance

Check your firewall and allow access on port 80.

Yes. The Issue was with the Firewall Utility in RHEL. Now it is working well. Thanks for the suggestion...
