I am having terrible problems getting my new ADSL modem set up under linux. Let me try to describe my setup.

My old ADSL modem was an Alcatel SpeedTouch (supplied by Bezeq). The new one is a SIEMENS SL2-141 (also supplied by Bezeq).

I have an internal network with a number of machines connected to a Linux server. The server uses iptables to enable certain machines on the local network (but not all of them) to connect to the internet transparently. Of course, the iptables script also sets up a firewall.

The internal network is all on 192.168.1.x and I have given the modem 192.168.1.8 (yes, I have set up the new modem to have this IP address).

With the alcatel, I connected with pptp. I have a script which starts or stops the pptp connection (ppp on or ppp off). ppp status gives me the current status of the ppp connection). When a connection is up the linux system runs its ip-up script which then calls my own ip-up.local script. This script changes the DNS script named.ca to point to the various internet root servers and then does a /usr/sbin/rndc reload. It also puts chronyc into online mode. When a connection is down the ip-down.local script puts chronyc into offline mode, sets named.ca to point to a null script, and does a /usr/sbin/rndc reload. I wrote a short graphical desktop utility which does the ppp on/ppp off graphically, and shows the connection's status on the status bar.

With this setup, the linux server runs DNS and also DHCP (to allow us to connect laptops to the network with a wireless bridge) and everything works smoothly and transparently. Running a short script allows or disallows internet access from certain computers on the network.

However, on upgrading to the SIEMENS modem I find that I cannot get things going. With the pptp script I get:

connect: Conection refused
Could not open control connection to 192.168.1.8

Even connecting via the web interface (which I do not want to do) I cannot connect from the linux machine. For the time being, all I can do for internet access is use my Windows XP laptop, which is configured to connect to any wireless network it finds (and the Siemens has wireless built in).

Is there any way I can get back the previous functionality that I had?
Should I ask Bezeq for my old modem instead of the new one? The main problem with that is that it does not handle the new faster speed ADSL which is not yet available in my area of the country, but soon will be.

Is there any other modem which handles faster ADSL and which can handle my requirements, or is there a way to get the SIEMENS working how I want?

Thanks in advance for any help,
