When you first connect a computer to the Internet, it takes only minutes before it's attacked by a hacker, according to the United States Computer Emergency Readiness Team. This is why US-CERT recommends a firewall in addition to anti-virus software to protect your computer. If your D-Link's built-in firewalls are causing problems, disabling them may help, but it could also make computers on your network vulnerable unless they have some other firewall protection. D-Link routers have two firewalls -- Network Address Translation and stateful packet inspection. Disable both to turn off the firewall settings on the device.

Step 1

Type the router's IP address in your browser's address bar. For example, type "," which is the default address for D-Link routers. Check the manual for the exact address.

Step 2

Click "Advanced" and choose "Firewall Settings" from the menu in the left column of the page.

Step 3

Click the box labeled "Enable SPI" to uncheck it.

Step 4

Click the radio button labeled "Endpoint Independent" for both UDP and TCP Endpoint Filtering to disable NAT and allow all traffic to pass through the router.

Step 5

Uncheck the "Enable anti-spoof checking" check box.

Step 6

Click "Save Settings" and "Reboot Router" when prompted for the router to reboot without its firewall.
