WAMP Cannot access on local network 403 Forbidden

To expand on RiggsFolly’s answer—or for anyone who is facing the same issue but is using Apache 2.2 or below—this format should work well:

Order Deny,Allow
Deny from all
Allow from 127.0.0.1 ::1
Allow from localhost
Allow from 192.168
Allow from 10
Satisfy Any

For more details on the format changes for Apache 2.4, the official Upgrading to 2.2 from 2.4 page is pretty clear & concise. Key point being:

The old access control idioms should be replaced by the new authentication mechanisms, although for compatibility with old configurations, the new module mod_access_compat is provided.

Which means, system admins around the world don’t necessarily have to panic about changing Apache 2.2 configs to be 2.4 compliant just yet.

For Apache 2.4.9

in addition, look at the httpd-vhosts.conf file in C:\wamp\bin\apache\apache2.4.9\conf\extra

<VirtualHost *:80>
ServerName localhost
ServerAlias localhost
DocumentRoot C:/wamp/www
<Directory "C:/wamp/www/">
Options Indexes FollowSymLinks MultiViews
AllowOverride all
Require local
</Directory>
</VirtualHost>

Change to:

<VirtualHost *:80>
ServerName localhost
ServerAlias localhost
DocumentRoot C:/wamp/www
<Directory "C:/wamp/www/">
Options Indexes FollowSymLinks MultiViews
AllowOverride all
Require all granted
</Directory>
</VirtualHost>

changing from "Require local" to "Require all granted" solved the error 403 in my local network

If you are using WAMPServer 3 See bottom of answer

For WAMPServer versions <= 2.5

By default Wampserver comes configured as securely as it can, so Apache is set to only allow access from the machine running wamp. Afterall it is supposed to be a development server and not a live server.

Also there was a little error released with WAMPServer 2.4 where it used the old Apache 2.2 syntax instead of the new Apache 2.4 syntax for access rights.

You need to change the security setting on Apache to allow access from anywhere else, so edit your httpd.conf file.

Change this section from :

#   onlineoffline tag - don't remove
     Order Deny,Allow
     Deny from all
     Allow from 127.0.0.1
     Allow from ::1
     Allow from localhost

To :

#   onlineoffline tag - don't remove
    Require local
    Require ip 192.168.0

The Require local allows access from these ip's 127.0.0.1 & localhost & ::1.

The statement Require ip 192.168.0 will allow you to access the Apache server from any ip on your internal network. Also it will allow access using the server mechines actual ip address from the server machine, as you are trying to do.

WAMPServer 3 has a different method

In version 3 and > of WAMPServer there is a Virtual Hosts pre defined for localhost so you have to make the access privilage amendements in the Virtual Host definition config file

First dont amend the httpd.conf file at all, leave it as you found it.

Using the menus, edit the httpd-vhosts.conf file.

It should look like this :

<VirtualHost *:80>
    ServerName localhost
    DocumentRoot D:/wamp/www
    <Directory  "D:/wamp/www/">
        Options +Indexes +FollowSymLinks +MultiViews
        AllowOverride All
        Require local
    </Directory>
</VirtualHost>

Amend it to

<VirtualHost *:80>
    ServerName localhost
    DocumentRoot D:/wamp/www
    <Directory  "D:/wamp/www/">
        Options +Indexes +FollowSymLinks +MultiViews
        AllowOverride All
        Require all granted
    </Directory>
</VirtualHost>

Hopefully you will have created a Virtual Host for your project and not be using the wamp\www folder for your site. In that case leave the localhost definition alone and make the change only to your Virtual Host.

Dont forget to restart Apache after making this change

I got this answer from here. and its works for me

Require local

Change to

Require all granted
Order Deny,Allow
Allow from all
