[SLUG] ADSL2 modems that just simply work with linux -- existed for adsl1

[R.G.Salisbury]

Hi All

I don't know of  any adsl2 modems that just work in linux.

Any one know of any such modems for ADSL2 that play well with linux.
Any links to good sites, documentation etc

I have tried Netcomms NB5 which I could not get to work. ( i hope it wasn't 
a fault with the modem)
The NB5 supposedly works with adsl1 & adsl2  & supposedly works with MacOS & 
linux ... but no support documentation that I can find.



Never  was a problem with adsl  "one" .

I have been using an Alcatel "speed touch home" modem.
That just simply works with linux  ...
& with factory defaults set.

Using Roaring Penquin software 
rp-pppoe-3.5-32.1.i386.rpm
it is very simple to set up.
Just run  "adsl-setup"

Only needs two config files needed for it to work:

chap-secrets  & pppoe.conf as shown below.

Any help very much appreciated

Thx
Roger


## chap-secrets
## Secrets for authentication using CHAP
## client server secret IP addresses

That modem works fine for me with Linux. My father uses the same
modem, also with Linux.

Funny enough, the modem itself runs linux :-).

I let the NB5 do all the ppp and authentication stuff.

All the ones with an ethernet port just work with Linux.  It's really 
the best approach as it'll never be obsolete or unsupported with your 
OS, no matter what happens in the future.  I've had good experiences 
with Billion.

I use the Netcomm NB1 ok.

It has the mode that (pretty much?) all modems have now where it can do
the authentication and NAT setup etc itself. In this case, you plug your
Linux box into it via ethernet, pick up an address via DHCP and log into
its web interface to set it up.

If you want to have Linux do all the authentication etc you need to go
to the modem's web interface as above, put it in Bridge Mode, which is a
bit of a pain. But at least you only have to do it once. The best
directions I've found for setting bridge mode on the NB5 are

I use pppoeconf (the Ubuntu package) to configure authentication and
such from there, and it hasn't gone wrong on ADSL 1 or 2.

It sounds like your trying to bridge the modem to have the host behind 
be the www interface.


I used to do that with ADSL 1 as well, but since moving to 2, I just let 
the modem(/router **) do the negotiation work and set up port forwarding 
rules for those things I want to go straight to the linux server host 
behind it.


You can even set up the modem to forward simply everything to the host 
behind if you still want to use that as a router. Only thing I guess you 
lose there is the ability to mangle/hide your internal IP from the call 
that goes to the outside. Of course if you are doing that, you are 
effectively introducing an 'interim' subnet and can at least mangle to 
the interim subnet's address, thereby still protecting your internal 
addresses.


But by still having iptables running on the box behind AND enabling the 
firewall in the modem, you gain an albeit minimal additional security 
layer. Obviously, it's not going to stop anyone who REALLY wants to get 
in, but it just adds that little extra layer of complexity.


** It seems pretty much every ADSL2 modem is also a router these days 
and thus has an ethernet port. Of course, that also means you need 
another power outlet as opposed to powering over USB like the Alcatel 
stingray did.



Kind Regards

Most ADSL modems these day are designed to be wireless routers. So
powering them separately makes sense. You don't want to have to turn
a computer on to power the wireless to be able to use a different
computer.

If you buy a router without wireless, it's really just the wireless
design but lacking the wireless components.

I've never had trouble with Linux and a router with an ethernet
port.  I've always had trouble with routers with USB ports (and
not just limited to Linux, but Vista and MacOS as well).

As for port forwarding versus PPPOE from a Linux server, it really
depends what you want to do.  I do PPPOE myself so I can offer
IPv6 and videoconferencing to users of my House Area Network.
But it's a lot more complex to set up than configuring port forwarding
(since you've also got to set up the server to do DHCP and NAT).

Billion are great. You can get their older models cheaper under the
brand "Open". They can even be flashed with Billion firmware if you
like. You will miss out on features like Annex M if you go down that
route though.

Draytek are the most reliable if you want something really solid, but
you'll pay up to 2-3x as much for them.
