It’s easy with Safe Surfer to install an effective porn blocker on a Netcomm NF4V modem. Along with protecting your privacy, we also use our own behind-the-scenes technology to block porn and other harmful online content. This guide will efficiently walk you through how to install protection.
Step 1: Install DNS
Enter the address 192.168.20.1 into the top search bar of a web browser (such as Google Chrome or Firefox).
Type admin into the username box. Check the bottom of your Netcomm router for a sticker containing the login password—this is different to the Wi-Fi password.
Installation for a fibre connection
Note: if you have an ADSL or VDSL connection, check the corresponding section further below.
Click the Advanced Setup section, then click the WAN Service menu. Click the Edit button.
Untick the checkbox found next to “Enable IPv6 for this service”. Click the Next button.
Click the Next button.
Click the “Apply/Save” button, then click the DNS section > DNS Server (this is found on the left-hand sidebar).
Click the button found next to “Use the following Static DNS IP address”.
- For “Primary DNS server”, copy and paste the following address into the text box: 104.197.28.121
- For “Secondary DNS server”, copy and paste the following address into the text box: 104.155.237.225
Click the “Apply/Save” button.
Installation for an ADSL / VDSL connection
Click the Advanced Setup section, then click the LAN menu.
- For “Primary DNS server”, copy and paste the following address into the text box: 104.197.28.121
- For “Secondary DNS server”, copy and paste the following address into the text box: 104.155.237.225
Click the “Apply/Save” button. If you have an ADSL or VDSL connection, restart the devices connected to the modem.
Verify the protection installation by visiting ExampleAdultSite.com inside a web browser. This is a safe website designated for testing if pornographic websites are being blocked. This site should be blocked.
Step 2: Sync IP (optional)
The Safe Surfer dashboard gives you access to comprehensive parental controls. The dashboard has a feature where you can create custom block rules for your Netcomm modem.
Pro tip: this feature requires a Pro Surfer subscription and works best when you have a “static IP” (that is, a non-changing public IP address) with your Internet service provider. If you would like to use the sync IP feature rather than downloading our easy-to-use apps or getting a Wi-Fi Lifeguard router, contact your ISP regarding how to get a static IP.
Open the Devices menu (found on the left-hand sidebar) on the Safe Surfer dashboard. Click the “+ New Device” button.
Click Wi-Fi & network > Use my existing router. Enter a name, then click the Accept button.
Go back to the Devices menu and click the Connect button found under the device listing just made.
Click the Plain DNS field, then click the Link button. This will sync any custom block settings.
You can now open the Blocking menu, select the router device from the blue bubble, and block categories. Click the Save button once you’re done. These changes might take a minute to sync over.
Protection complete
Great work! The devices connected to this home router should now be protected. Visit our easy-to-use online dashboard to start monitoring traffic and blocking content from our premium categories with an affordable Pro Surfer subscription.
