Using Extranet Proxy Server
The second scenario is that a proxy server is placed in the Extranet (such as DMZ), which all users from
the Intranet or the Internet are able to access. For example, the following diagram shows that a proxy
server of an organization in the DMZ will be used.
Caution: A special scenario is that a proxy server is placed in a zone like Intranet – where users can
reach each other without going through the system. In this case, whenever any one of users in the
Intranet has been authenticated and connects to the network via the proxy server, other users using
the same proxy setting in their browsers will be able to access the network without any authentication.
Therefore, to stop the risk, it is strongly recommended to put all proxy servers outside the Intranet.
Follow the following steps to complete the proxy configuration:
Step 1. Log in the system by using the admin account.
Step 2. Network >> Proxy Server >> External Proxy Servers page. Add the IP address and
port number of the Proxy server into External Proxy Servers setting. Click Apply to save
the settings.
Step 3. Make sure that clients use the same proxy server settings. Please also configure
appropriate exceptions if there is any traffic which is not needed to go through proxy
server – for example, there is no need to use proxy server for the Default Gateway
(192.168.1.254).
