When you install a new D-Link router it is the same thing as creating a new network. Software firewalls and sometimes even the Windows firewall has to be told that you have a new trusted device on the network.

You can either set the D-Link router has a trusted network or it may require the MAC address from the bottom of the router. If you do not know how to change this in your firewall software, please contact technical support for whichever software firewall you are using for assistance in allowing the new router to be a trusted network.

This article teaches you VPN config about D-Link Firewall and DI-804HV,With the DFL-800 as an example.

1. Go to “System” → “DNS” and enter a working DNS server IP, here we use our ISP’s DNS server.

2. Go to “System” → “Misc. Clients” → “Add” to add a DDNS client, here we choose dyndns.org DDNS client.

3. Then enter the full domain name and your account info.

4. Go to “Objects” → “Address book”, previously, we use an IP on the remote gateway, here, just change the IP to the domain name, here we assume the other side (DI-804HV also uses DDNS and has the domain test1.dyndns.org setup). Click on the “remote-gw” object, and modify the IP to “dns:test1.dyndns.org”. Make sure “dns:” is entered before the domain name.

5. In DI-804HV, just replace the remote gateway IP to the DDNS domain name we set up in D-Link DFL-800 (test.dyndns.org)
