Proxy Deployment

You can deploy Proxy Server in your network by enabling Web Proxy Auto-Discovery (WPAD) for use with DHCP servers or for when your Synology NAS operates in wireless router mode. WPAD is a protocol that allows client devices in the local network to automatically configure proxy settings. Users will not have to manually configure their browser proxy settings.

To enable WPAD:

  1. Check Enable Web Proxy Automatic Discovery.
  2. In Network interface, select the network interface you want Proxy Server to operate on. A wpad.dat configuration file will automatically be generated in the web shared folder. A DHCP configuration file for Synology DHCP Server will also be created.
  3. Click Apply to save your settings.
  4. Next, if you have enabled DHCP server on your own router, please disable it. The next few steps will show you how to enable DHCP server on your Synology NAS.
  5. Go to Control Panel > Network Interface. Select the network interface you chose above and click Edit.
  6. Go to DHCP Server and check Enable DHCP server. Then check Enable Web Proxy Automatic Discovery. You should see the filepath for your wpad.dat configuration file automatically appear in URL.
  7. Click OK to save your settings.

Note:

  • To use your own wpad.dat configuration file, please name the file as "wpad_custom.dat". Then save it to the web shared folder (\web in File Station) and restart Proxy Server.

Proxy Server can also operate as a transparent proxy, forcing all client devices which connect to the Internet via your Synology NAS in wireless router mode to relay Internet browsing traffic through Proxy Server.
