Experiment 10: Exercise on installation and Configuring a proxy server for Internet

Access.

If you employ a proxy server for Internet connectivity, you can configure the Manager or your
devices to connect to that server for proxy service. This is necessary if you want to download
updates directly to Manager from the Update Server or if you want to download host reputation
and country of origin information during integration with TrustedSource.

The Manager supports application-level HTTP/HTTPS proxies, such as Squid, iPlanet, Microsoft
Proxy Server, and Microsoft ISA.

NOTE: To use Microsoft ISA, you must configure this proxy server with basic
authentication. Network Security Platform does not support Microsoft ISA during NTLM
(Microsoft LAN Manager) authentication.
NOTE: SOCKS, a network-level proxy, is not currently supported by Network Security
Platform.

To specify your proxy server, do the following:

Task
1. Login to the Manager instance.
2. Select Manager → <Admin Domain Name> → Setup → Proxy Server. The Proxy
Server page is displayed.
Proxy Server Settings

3. Type the Proxy Server Name or IP Address. This can be either IPv4 or IPv6 address.
4. Type the Proxy Port of your proxy server.
5. Type User Name and Password.
6. Provide the appropriate URL. You may test to ensure that the connection works by entering
a Test URL and clicking Test Connection.
7. Click Save to save your settings.
When the Manager or the device makes a successful connection, it displays a message indicating
that the proxy server settings are valid.

How to find proxy settings in Windows:

How to set up a proxy server in Windows:

Here's how to set up your Windows PC to use a proxy server on Windows 8 or Windows 10:
1. Press the Windows + I keys simultaneously to access the Windows Settings menu.
2. On Windows 10, click Settings > Network & Internet > Proxy. On Windows 8,
click Settings > Network Proxy.
3. Under the Manual Setup section, set the “Use a Proxy Server” toggle to On. Make sure the
“Automatically detect settings” toggle is also on.
4. By default, Windows automatically checks to see if your business, school, or local network
already has an automatic proxy server setup ready to run for you. If it does, Windows tells
you its name, and encourages you to follow its instructions.
5. Assuming that Windows finds a PAC file, in the Automatic Proxy Setup, set the Use Setup
Script switch to On.
 6. Enter the script address and click Save.
Congratulations! You're done and ready to proxy.

checkbox. Enter your account name and password in the Username and Password fields.
6. Click Save.
That's all there is to it. You're now set up to use your proxy server on Windows. The next time
you use the internet, you'll be using the proxy server.

How to set up a proxy server in Android:

With Android, you must configure proxy settings for each network you use. In addition, the
proxy will only be used by your web browser. Other internet applications may choose to use or
ignore the proxy based on their own internal settings. This is another reason why VPNs tend to
be better choices — when you use one, it covers all the internet traffic from your device.
1. Open Android’s Settings and tap Wi-Fi to view a list of Wi-Fi networks.
2. Long-press the Wi-Fi network name for which you want to change the proxy settings.
Tap Modify Network.
3. Tap Advanced Options.

4. Tap Manual to change your proxy's settings. Enter your hostname and proxy port.
OR
 If you have a Proxy Auto-Config (PAC) file, select Proxy Auto-Config and Android will
prompt you to enter the PAC address.
5. Tap SAVE.
