advice about ADSL

An advice about the following would be very appreciated.
Now having dialin i want to switch to ADSL.
Here in the Netherlands the main provider is KPN, who also is the
main telephone company.
I'm an avarage expierenced linux user, not a pro, can write some scripts
in bash (while read.... some awk,sed) but when it comes to networking,
reading this newsgroup ,i'm new. Can find the files, ppp, hosts etc.
but creating addresses,netmasks ,about iptables and so on, looks very
difficult to me.
What i want to do is order the, by the provider supplied ,modem/router
speedtouch 510.
I already downloaded the manual which says i can configure it with my
browser.
An ethernet card Dlink DFE 530 TX is installed ( according to the DSL-HOWTO
i can ping it).
My question is : Do i get it to work, or are there many more difficulties.

ADSL is about as easy as it comes. You have to configure DHCP on the
interface that talks to the modem, and you have to make sure your routing
tables don't get mangled. Other than that, it works automagically.

The only trick is if you have more than one interface, and one is DHCP
assigned, the other is fixed (as in my setup). You need to configure dhcp
to only use the interface that is talking to the ADSL modem.

This is a quite easy job, on your linux box you just need set up dhcp
for your network card (refer to you distribution's documentation). The
dhcp server on the Speedtouch will then respond and assign an ip adress
to it (along with broadcast, netmask, and gateway adress - you don't
need to worry about this). After that you can access the web frontend of
the Speedtouch (check the manual for the default ip), feed it with the
account data of your dsl provider and change configuration if needed.

Ok, I'm new to this, and trying to learn a little more; so, in this context,
would it be the same if his provider uses pppoe? (it is really a question
here).

For as far as i know ( i want to connect ,he he ) the provider uses
pppoe or pppoa ( all information about how fast, and easy inserting
installation disk, but about protocol hard to find ) simultaniously
with my normal phone traffic to come into my house.
Goes through the modem, comes into the router, and then i should use
dhcp (dhcpcd, client, dhcpd ...) the make a connection between the
router and my pc. The router handles the pppoe(a) signal.

Yes. The Speedtouch router is in fact a separate computer with its own
OS (probably even some kind of Linux ). It will take care about the
internet connection independently from its connected computers, thus
dealing with pppoe. If your provider sells this device together with
its dsl service I wouldn't worry if it can handle whatever protocol
is necessary. The computers connected to the router don't need any
ppp setup. They will just forward any internet requests to the router
through the local (ethernet) network. This is the benefit of having a
stand-alone router like the Speedtouch instead of a plain dsl modem.

Ok, thank you, I think that now I start to understand a bit more!

So, OTOH, if a given ADSL provider requires its clients to install an
specific "dialing" software (not really dialing, but emulating for ADSL
authentication purposes, softwares like raspppoe for Windows or, in, Linux,
the pppoe program provided by www.roaringpenguin.com), in fact the router
modem (in a case I especifically know, an Speadstream "something" router
modem) might be (currently) set in "bridge" mode instead, not having all
features of an standard "router". Could this be the case?

So, in fact, it seems also that it could be possible to reconfigure the
router into "router" mode again, have the pppoe authentication made
therein, the "router/modem" dealing with it. Could it be the case?

Thanks!

Paulo

I don't really get what you're meaning. A dsl router like the initially
mentioned Speedtouch device is basically a stand-alone computer with a
network switch and a dsl-modem built-in running a special OS with all
required software for routing, firewalling and ppp(oe) dial-in. And of
course it can handle these tasks simultaneously.

Never mind, maybe it is just different here. I was talking about dsl
"modems" and "routers", and "routers" being used as simple modems.

It is just that for some dsl providers, the dhcp approach works (and
knoppix, for example, can detect it from cd and go on-line immediately).

Others, especially when pppoe is implied, dont. dhcp directly won't put you
on-line. You need a software (like the rp-ppoe, from
www.roaringpenguin.com) to deal with the issue. I know this because have
already seem it happen, but was trying to understand better.

Never mind, thanks anyway!
