Help with Dynalink ADSL Config

[Dave Clarke]

I'm looking for some help with the configuration of my Dynalink RTA770 ADSL
Router. Currently I've got it hooked up for general net access. I would like
to use it to also connect a web server to the net and my networking
knowledge is fairly basic. The router has a built-in firewall, it supports
port mapping, static routes, and a DMZ. So I figure what I need to do is
attach my server on a separate subnet and direct all incoming traffic on
port 80 to that server, blocking all other incoming traffic using the
firewall. I realise there is a certain level of knowledge required to do
this and I'm happy to spend the time so long as I'm learning the right
stuff.

Unfortunately the documentation that comes with the router is extremely
rudimentary and I've been unable to find anything I would call useful. Has
anyone had experience doing this kind of thing, am I approaching the issue
correctly, and in particular is there anywhere I can get good information on
how to set this up? Are router configuration commands standard or are they
vendor specific?

Any helpful suggestions would be gratefully accepted.

Dave

Hi Dave,

I am not familiar with the RTA770 but I can let you know the gist of what
you need to know.

Your RTA770 should have two interfaces, a WAN interface and a LAN interface.
The LAN interface should have an IP address of something like 192.168.x.1
where x is most likely 0 or 1. This will mean your computers on your network
will have IPs that look like 192.168.x.y, where y is between 2 and 254.

Rather than throwing your web server on a separate subnet I would just throw
it in the 192.168.x.y range of IPs. To be nice give it an IP like
192.168.x.254. Now you have to decide what services your web server wants to
offer to the world. If you are only going to be serving normal webpages you
will probably just want to pinhole port 80 through to 192.168.x.254. You do
this in the Dynalink router. If the webserver is going to be offering many
services, eg. HTTP, HTTPS and FTP, you will probably want to set-up a DMZ.
Just tell the DMZ function on the Dynalink to forward all connections to
192.168.x.254 .

Hopefully this helps.

Cheers,
Dave
