Question about D-Link NetDefend DFL-700 Firewall

1 Answer

Faulty DFL-700 image - missing FWCore.cfg

I've a problem with a used DFL-700 unit.
At boot time (checked via serial connection)
it continues prompting the text reported below.
Trying to reset factory default via button or console
brings to the same results: nothing.

Tried to read the mini-ide flash/ide card on a notebook
with Linux (installing it as a hard drive) without any
results (the flash card doesn't get recognized).

Any ideas?
Dlink support gives no help or solution, since the unit
is outside warranty coverage.

    The firmware cannot be upgraded until the Web interface is activated; an action that the error reported prevents to happen.

    Tried to remove the flash device from the board, and using a 44 pin male-male 44 to a USB<=>notebook hard drive adaptor but neither Windows nor Linux (latest Knoppix) cannot see the flash device.

    In the following days I'm going to try to attach the flash device via a 44 pin male-male to a 44 pin mini-ide to 40 pin IDE adaptor and connect all the things to a normal PC, not using the USB adaptor.

    IDE controller I suppose is working correctly, since it loads the serial console code.

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.

    The serial code might not be loaded on the flash, but on a EPROM or embedded chip.

    I will try and find out what the flash drive is formated with, so maybe you could update a normal hard drive and them clone it to the flash.

I have two different domains that are connected via VPN connection through two routers. I can ping from domain to domain via IP address on clients and servers. However I can only do a net view command 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.
Pay close attention to #s 4 and 5 - I suspect XP pro might not be open enough.

Connection to ftp closed by remote host

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.

Traceroute does not work

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.

Dfl-1600 sytem restart

Sounds like the firmware is looping for some reason. Try this to reset defaults:
Step 1: Make sure the unit is powered off.

Step 2: Press and hold the reset button located on the back of the firewall. While continuing to hold the reset button, power on the firewall.

Step 3: Continue to hold the reset button for 30 seconds after the unit is powered on.

Step 4: Release the reset button and the firewall will be at factory default settings.
