ADSL Modems

Hi,

Does anyone know of a linux compatible, external, non-USB ADSL modem
that's on the market today and that allows the real ip to be on the
machine which handles the connection, rather than on the modem? 

Historically the 3com Dual Link has allowed this with the use of PPPoE
and the Alcatel Speedtouch Home/Pro via PPTP of which i've used both,
but neither are sold new any more in NZ to my knowledge.

Can the Cisco 827 or 837 do this? (altho this would be an incredible
waste of hardware i know)

Thanks

Campbell

Re: ADSL Modems

Hi Campbell,

The Speedtouch 510 will do what you want, it has 2 options PPTP (like the
old ST Home/Pro) and DHCP spoofing. I have used these in both modes and can
recommend them.

I believe the DSE XH1149 will do this.

Re: ADSL Modems

I believe that any router supporting DMZ Host, would enable you to do that.
With DMZ host, you still get net connectivity via the router from other
computers.

Re: ADSL Modems

Nokia M1122's support this well, I have used one on my Redhat 7.2 server
quite a few times.

Re: ADSL Modems

DLink DSL500? I believe it has the functionality although I've never used it...

RE: ADSL Modems

I think a DMZ is quite different to what this person wants. (Dlink DSL50x
and Dynalink 220/300 both definately support DMZ's, many other Routers also
do)

With a DMZ the Router still has a real world IP address, and an Internal IP
address. All requests inbound from the real world are pushed towards a
certain host on the internal network. This internal host is still, as far as
it is aware on a private IP address. If you configure this internal host to
be on the same public IP address as your ISP assigns you, things will break
and jebus will not be happy.

Time for some text diagrams...

What a DMZ achieves:

ISP
 |
210.x.x.x
 |
DSL Router
 |
10.0.0.1
 |
DMZ
 |
10.0.0.2
 |
Internal Host

As you can see from the above, the Internal host still believes it is on

RE: ADSL Modems

The Dlink DSL 500 & 504 allow for DMZ between the external IP and the
internal IP, therefore allowing uncompromised access to the internal machine
from the internet. Although the internal machine still has an internal
address.

PPPoA allows this if you terminate the PPP session on the host you want to
have the external IP on. The 3com Homeconnect does this by turning the PPPoA
on the ADSL line into PPPoE packets on your ethernet, which you then terminate
at your convienience. Most of the other modems mentioned (Alcatel Home, Nokia
M1122) do the same thing but use PPTP as the modem - host protocol.

For obvious reasons all internal modems provide this because the host computer
effectivly is the modem.

NetGear DG814 Router MTU Setting

Recently  started using Netgear DG814 ADSL Routers 
(with built in 4 port switch and Dyn DNS support)

I reflashed the firmware to the latest version for VPN compatibility and 
did a factory reset as advised by Netgear support.

The routers worked well apart from problems with inbound POP and 
PcAnywhere, they became very hit or miss in the working department..

After much head scratching I set the setting "NON STANDARD MTU" to 1500
(it was I seem to recall 1458) suddenly the units started to perform as 
expected and all works well.
Resetting to factory defaults or auto detecting will NOT set this 
correctly.

Has anyone else used these and got anything to offer re 
problems/solutions?

BTW they support dyn dns in the router which makes them a very interesting 
unit.....
