20 Most Recent D-Link NetDefend DFL-700 Firewall Questions & Answers

You have both equipments with the same ip address. Connect the PC to the firewall, login and change the IP first.

If your cisco vpn client is behind the natted device then you need to allow nat traversal in the head office firewall and if you connect the vpn client through data card it will connect,

this will not be a problem of your firewall. it will almost certainly be a password problem. ftp uses ports 20 & 21 but if you have disabled the firewall this cannot be the cause.

To perform a factory reset using the reset button do the following:

Step 1: Make sure that the DFL-200/DFL-700 is on.

This is an excerpt from a MS Technet page for error 53:
Resolutions: 1) if it is domain environment, check your WINS; 2) if it is peer-to-peer workgroup, enable NetBIOS over TCP/IP; 3) make sure the machine is running; 4) make sure file and Printer Share enabled on remote computer; 5) make sure client for ms networks is enabled on local computer; 6) make sure you type the correct name. 7) Make sure no firewall running or any security setting.

What is the error you are getting?

Do you have an email server in place? If so, you need to setup port 25 for inbound access to the IP address of the email server. I would suggest that you don't allow all as that will open up everything and kind of negates the reason to have a firewall. Some ISPs block port 25 though and use port 587.

If you don't have an email server then the problem might be with your email client configuration.

Possible problems:
1. IDE Flash device is damaged
2. IDE controller is damaged
2. Firmware is corrupt

Try and download the firmware, and install. You should then get a better idea if the IDE device or controller is bad if it won't install or see the device.

Is the McAfee Firewall blocking incoming requests (netbios probably)

You have to allow the following:
ICMP type 8 (Echo) from your DMZ to the Internet (a.k.a outbound)
ICMP type 0 (Echo reply) from the Internet to your DMZ (a.k.a inbound)

This will be done by adding the rules in the firewall section of your DFL-700.

have you used the factory default switch?

I am sure it is now toast and you cannot downgrade if the wrong firmware has been installed. I would ask D-Link.
