Cant see website in own network

[gnawz]

I have a Linux box (Redhat) which handles my network and mails.

However, sometime we cannot see our website within our network yet it is viewed outside.

What could be the cause of this?


My other question is how do I reverse my IP address in my Linux box?

can you still ping the webserver? even when the website is down?
also you might want to check your logs to see if the apache (I assume) has troubles with downtime.
