How to enable HTTP-based authentication requests only through the external ip?

Question

I have apache server on ubuntu 12.04 with virtual hosts and router forwarded 80 port to one of them. The directory is configured http-authentication. I need to provide authentication for the requests only when a request comes in the "outside", that is, only when the request comes through the external ip, and if I call from inside the network (or from the server at localhost), no authentication is required.

Thanks in advance for your help. Sorry for bad english.

You can use the allow from directive in conjunction with your http authentication directives in your httpd.conf file (or .htaccess file) to specify a range of IP addreses for which http authentication will not be required. See .htaccess / .htpasswd bypass if at a certain IP address for more info. Just specify your range of inside ip addresses in the allow from directive.
