And with a small or medium-sized business network, it makes sense to use a separate, dedicated appliance to minimise configuration time. The alternatives are either to run a software firewall on one of your servers, which can lead to high configuration requirements, or hope that the firewall in your router is up to scratch.
You would normally relax your Internet traffic filters for the DMZ, as they are applicable only to externally-accessible servers, not the whole network. This means uninvited traffic from the outside world never traverses your local network, making the LAN just that bit safer.
The DFL provides complete firewall functions. Setup can be performed mostly using drop-down boxes for instance, you select the IP service whose packets you want to either drop or allow , which makes setup easy and quick. You can create separate rules for any combination of the three ports in either direction. If you want to delve deeper, all service filters are configurable. Should unauthorised traffic get as far as the LAN, an intrusion detection system allows you to log attacks, locate the source IP address, notify you by email and set up policies to restrict incoming traffic from specific IP address sources.
Now we need to find the port forwarding section in your router. Here's how you do it. Starting from the first page in your router:.
Put a name for this forward in the Name box so that you can remember why you set this forward up. The name does not matter so pick something that has meaning to you. Use the Service dropdown box to select the protocol type of the ports you are forwarding. These ports can be entered as a list 23,24,25, a range , or a combination of both 23,45, Enter the IP address to forward these ports to into the Pass To box.
If you are forwarding ports so you can run a program on a device other than your computer then you can enter your device's IP address into that box.
Now that you have forwarded ports on the Dlink DFL you should test to see if your ports are forwarded correctly. To test if your port has been properly forwarded, you can use our Network Utilities tool, which includes a free Open Port Checker. Then slide the top-cover forward and it will come off.

The files extracted from the above image. I'm no longer sure on how the CF-card is partitioned and formatted as I don't have a working original anymore, and I may have fucked it up while trying to write other versions to the card. If you have the possibility read your card and give me some more information about this it would be most appriciated.
The Partition-table and MBR may be a little odd - as it's not recognized by linux fdisk. However I do now believe that it is possible to use TFTP to get a remote image and write that in memory..
Bandwidth management guarantees bandwidth for different services. The DFL protects your network from attacks. It can be configured to log all attacks, locate the source IP address generating the attack, send the attack report notification to a specified e-mail address and establish policies to restrict incoming traffic from specific IP address sources.
