How to Block the Internet on a Router

by Ruri Ranbe

The Internet relies on the hypertext transfer protocol and HTTP secure (HTTPS) to transfer data over a network. HTTP communicates over port 80 and HTTPS, port 443; most firewalls leave these ports open by default. Although routers allow you to forward restricted ports in the firewall, not all devices permit you to block open ports. If you have a Linksys, D-LINK or TRENDnet router, however, you may be able to block the Web using access controls.


Open a browser, type "" into the address bar and then press "Enter." Log in to the router using "admin" as the username and password.

Select "Access Restrictions" from the main menu and choose "Internet Access Policy" from the submenu.

Create a name for the policy and then set Status to "Enabled." Click "Edit List" to open a new window.

Enter into the appropriate fields the MAC address, IP address or IP address range to block. Click "Save Settings," then "Close."

Click "Deny" to block Internet on the applicable devices. Check "Every Day" or select the days on which to prevent access.

Click "24 Hours" or set the time range during which access should be blocked.

Select "HTTP" from Blocked Applications and then click the ">>" button to add the protocol to the block list.

Repeat Step 7 to add HTTPS to the block list. Click "Save Settings" to restrict Internet access on the network.


Open a browser, type "" into the address bar and then press "Enter." Log in using "admin" as the username and password.

Click "Advanced," then "Access Control." Check "Enable Access Control" and then click the "Add Policy" button.

Click "Next." Enter a name for the policy and then click "Next." Choose "Always" from the "Schedule" drop-down menu to restrict Internet access permanently, or select a pre-defined schedule.

Click "Next." Select the appropriate computer from the Computer Name drop-down menu or click "Copy Your PCs Mac Address" to block the Internet on the PC you're using.

Click "OK" to add the device to the policy and then click "Next." Click "Block All Access," then "Save."


  • The steps to configure access restrictions on a D-LINK are almost identical to the steps on a TRENDnet; the interface is the same for both. Log in at "" using "admin" as the username and leaving the password blank. Click "Advanced," click "Access Control" and follow the steps in the TRENDnet section.
  • If you've yet to set up a schedule on your D-LINK or TRENDnet device, click "Tools," click "Schedules" and then choose the appropriate days and times from the options.


  • The steps to set up access controls may vary depending on the product model and firmware version.
