D-Link ADSL DSL-500 Modem and Router
The DSL-500 from D-LINK is in my opinion a much better unit than the Alcatel
Speedtouch Pro. The software is more modern, with updates available over the
web from the D-Link WWW Site (http://www.dlink.com.au.
My Comments
Upgrade the Firmware
My unit came with v1.14 firmware. I found that this was too old to connect
to my ISP (AlwaysOnline). I downloaded the firmware (2.01b5) from D-Link and
installed this software on my computer. I then ran the software, and this
upgraded the firmare. At the end of the process it responded with a message
about a timeout, and when I connected the modem I found that the old version
of the firmware was running. Restarting the modem fixed everything.
Do Not Use Netscape 6
I tried to use Netscape 6 to configure the unit. This did not work well,
since the left hand menu is some type active component. Using IE6 worked.
Enter The User Details Correctly
This is not too hard. Just make sure you do it correctly.
Set Up NAT forwarding
Because I needed to use NAT to run a server, I went to the NAT menu, and
enabled it. The trick is to also enable DMZ STATE. Then I needed to enter
the IP address of my server on my network. Since this was not on the same
ethernet IP range I needed to change a few more things.
Change the IP Address of the Modem
In my case I use an addressing scheme where the interface number on my
firewall lines up to the IP addresses on that link (eth3 is 192.168.3.1).
Also my firewall uses .1 for the last octet address for all interfaces (see
the address above). Therefore I needed to change the IP address of the
unit.
I changed it to 192.168.3.250, and decided not to restart the unit at this
stage. I then went to DHCP and changed all the DHCP settings, just in case I
want to use it at some point in the future. I then restarted, but I needed
to do one more step
Create a Static Route
At this point things almost work. Outgoing services sometimes might work,
depending on the WEB PROXY in my firewall. Incoming services did not work.
To fix that I needed to create a STATIC ROUTE to point any IP Packets of
192.168.0.0/255.255.0.0 to use gateway 192.168.3.1 (my firewall). This fixed
most things so that they actually work.
Statistics
The statistics on the DSL-500 are good. They give you all the information
you need about signal to noise and error rates without needing to delve into
the internals of the modem. It also even states the distance from the
exchange to the nearest thousand feet.
And to top that off a graph is available showing the performance of the
entire link. All in all the DSL-500 is a good buy. Superior to the Alcatel
SpeedTouch PRO in every way.
