Configuring a Sagem modem

[technossomy]

Dear all

I have two computers (WinME and Win98) hooked up to a F@st Sagem 3202 ADSL modem. How do I access one from the other via the modem such that I have a LAN? Perhaps I should share folders and allow access from either? In that case I may be using the Internet after all, whereas it should preferably be a LAN with no outside line.

Thanks in advance

Hi technossomy,

Could you describe your set up a little better? Do you have NICs in both computers? How are these computers hooked up to the modem? Does the modem contain a switch or router? Are you using cat5 cable to connect?

The more info you provide the better...

[technossomy]

Steve

Thanks for getting back. The set up is as follows:
- PC1 has a NIC and is connected via UTP/Ethernet to the modem, but not sure whether that would be straight or cross (if that matters)
- PC2 has a NIC and is connected via UBS to the modem

Please enlighten me on how to check whether the modem in question has a router/switch/hub.
I am not familiar with cat5.
Also, if I need to ipconfig both computers, please let me know.

Tech, what country are you in? I've spent some time trying to find a manual for that modem with little success. It seems Sagem is located in every country except the USA, which is where I am. I've found reference to the 800/900/908 models but nothing about a 3202.

Seeing that you have at least two ports (RJ45) on the modem, I presume there is at least a switch if not a router built into the unit.

Go to a command prompt on each machine and type in ipconfig /all then hit enter and get the ip address for each computer. Then try to ping each one. At the command prompt type ping then a space and the ip address of the other computer and hit enter. This will let you know if you are networked.

Let us know how this turns out or if you have any trouble with the steps...

Hi Steve

Thanks again. Of course I meant "USB" as opposed to UBS, for the record.

I was once informed that the modem in fact does contain a router or switch, but since I don't know the difference, I quickly forgot the specifics. The manuals I found are all in French, but none of a technical nature.

The ipconfig /all failed, giving me the help file instead, so I tried just ipconfig instead.

PC1 (connected through Ethernet):

Windows ME IP-configuration
0 Ethernet adapter :
IP-address . . . . . . . . . . . : 192.168.5.10
Subnetmask . . . . . . . . . . : 255.255.255.0
Standard gateway . . . . . . : 192.168.5.1

1 Ethernet adapter :
IP-address . . . . . . . . . . . : 0.0.0.0
Subnetmask . . . . . . . . . : 0.0.0.0

PC2 (connected through USB port):

2 Ethernet adapter :
IP-address . . . . . . . . . . . : 169.254.175.246
Subnetmask . . . . . . . . . : 255.255.0.0
Standard gateway . . . . . . . :

3 Ethernet adapter :
IP-address . . . . . . . . . . . : 192.168.2.10
Subnetmask . . . . . . . . . : 255.255.255.0
Standard gateway . . . . . . . : 192.168.2.1

I've tried pinging all IP addresses and standard gateway addresses, but consistently a 100% loss. Of course, pinging the machine itself works and 0.0.0.0 I didn't try.

Hope this helps and thanks for your anticipated assistance

Without a manual for that modem, I kind of at a loss here. You seem to have two separate gateway devices.

You can enter each gateway address into a browser address bar and see if you can access the setup utilities for the device. We can get some information there.

Are you able to get on the internet with both computers?

A lot of questions, not many answers, yet... ;)

[technossomy]

Hi Steve

In fact, I accidentally entered an IP address into a browser bar and got to the config pages of the modem. A wonderful utility, because it seems I can set it up as either a DNS server or DHCP server. I'll do some research into the differences and benefits of both.

So suppose I select the latter. I open the DHCP relay, it will automatically configure itself as a DHCP server and all clients connected to it will need to be configured as clients to this server via some OS specific networking utility?

Also, what does it mean that I cannot use the attribute "all" for the ipconfig command?

As for your other question: both computers work fine and are web-enabled.

[Steve]

OK. We're making progress. I don't think you want to set it up as a DNS server but you do want to enable DHCP. Dynamic Host Configuration Protocol will assign ip addresses automatically. It's a good thing.

On each of your computers, you will want to access the network properties through the control panel. Make sure each is set to obtain ip address automatically. Make sure you have tcp/ip and NetBEUI installed under network protocols, for each computer. And of course, you must have shared folders on each computer.

EDIT: BTW, I have never seen a case where the ipconfig /all command didn't work. I don't really have an answer for this. Are you sure you are typing it in properly?

[technossomy]

Hi Steve

Thanks again for your responses. I haven't set up the network yet, although I had been researching the background of DHCP. One other thing, what is the difference between a DHCP server and DHCP relay. Do I need to have both simultaneously?

Also, the configuration screen asks for a from-port and to-port for the DHCP traffic. How do I typically find out the port numbers?

Tech

[Steve]

The DHCP server contains the IP addresses, lease duration, and TCP/IP configuration information and assigns them on demand by client machines.

DHCP relay is software that assists in forwarding the DHCP packets between subnets in a segmented (routed) internal network.

I haven't had occassion to use relay software and wonder if it's necessary in your situation. Neither have I had to assign ports for DHCP configuration. It might be part of the relay software.

[technossomy]

I have done the following:
Computers are connected via the router which came with the modem
Computers both have unique names under 8 characters
Computers are both on the same Workgroup name
Computers have the IP addresses for both PCs in the trusted zone for software firewall/connection
Both PCs are on
Both computers have at least one file that is shared and have been given access rights for those files.

So let's say I have an IP of 192.168.5.10 on computer 1 and type that into the browser's address bar of computer 2, I get a "connection refused" alert. What am I doing wrong?

Thanks in advance

[technossomy]

Does anyone have an answer to my latest questions? I would not like to start a new thread and I am still at a loss over how to remedy the situation.

Thanks all in advance

The F@st Sagem 3203 ADSL modem is a modem used by Wanadoo in France, Brittain and the Netherlands.

You can connect to it by USB cable or ethernet (RJ45 port). The cable used to connect ethernet and networking card is called a cat5 cable. In fact, it uses a crosslinked cable.

The USB connection uses 192.168.4.1 as IP address and hands out 192.168.4.10-192.168.4.20 to attached computers; and the ethernet uses 192.168.5.1 as IP address 192.168.5.10-192.168.5.20 to attached computers.

If anyone has/finds a manual I'd like a copy!

ipconfig /all works in windows xp (and 2000???), in win98 it is (in a dos window) 'winipcfg'.

Have you tried in windows explorer to type the IP address of one (say 192.168.5.10) on the other pc?

[technossomy]

Hi Emka

Thanks for your response. I don't have a technical manual either. But a lot of information can be garnered if you open up its admin page, which I believe is 192.168.2.1 and user admin/admin.

If I execute your suggestion, and in any direction (wireless to Ethernet, Ethernet to wireless, USB to Ethernet and Ethernet to USB), all I get is a "The page cannot be displayed" error page.

Thanks in advance

To whom it may concern, the chipset of the modem Sagem F@st 3202 is as follows:

Analog Devices AD6833KB 0442 545587.1-0.2
Tecom BT3014 Bluetooth Class1 HCI Module P/N: 231-251139 S/N: H4K31659

You need to buy a book on computing and networking and read it.
You cannot browse the other computer through Internet Explorer. You do not need a DHCP relay. Do a google search on DHCP Relay agent and you will see that this is not necessary with a two computer network. You can find port numbers for applications by simply doing a google search for "port numbers" you should really find a book on basic networking and read it. Your thought processes are too jumbled with irrelevant details. It is simple to fix, you obviously have the will to learn, so start with the basics and work your way up.

Thanks for your response. So far, I have been trying to work it out and your suggestions are welcome as are anybody's. There are really two threads here going on at the same time:
1. What are the technical details of the Sagem 3202 modem
2. How to set up a SOHO network for 2+ computers based on some specific details, such as router, OS etc.

The second is of biggest importance to me and no inroads have led to anything but "connection refused" or similar. If anyone could tell me which switch to flip or which toggle to alternate, that would be even more helpful.

tech,
A manual of the modem can be found at:
http://mathieu.marcantoni.perso.cegetel.net/livebox_EN.pdf

I have the same problem, every computer that connects to the router by a different route (wireless, ethernet or bluetooth), becomes part of a different subnet. My provider responded, when I asked, that there is no solution to this problem. I do not believe this, but have not found a solution yet.

So the big question remains, how can two computers in different subnets (192.168.5.x and 192.168.3.x) share the same workgroup?

[Variable]

Thats what a router does. It can route between networks.
Workgroup and subnets are two different things. Two networks could have the same workgroup name and be on different subnets. The problem you have is traffic destined for a different subnet will go out the address of the Default Gateway. That is what the default gateway is, a route out of the local subnet. Usually this is a router. Routers know how to route, hence the name routers. You can also add route statements inside a router. The problem you describe is not descriptive enough so I am not sure how a router will do bluetooth fo rinstance. But simply communicating together should be no issue if each device has connectivity. The networking problem is one of configuration, generally speaking. Unless you do not have the hardware...

[kpnnwc]

I think I have solved my problem:

I wanted to install a shared printer on the network with the Sagem 3202 as a router. The problem was that the Sagem 3202 modem defines different ranges of IP addresses to the different interfaces. So a computer or handheld linked to the router via a different interface is within a different subnet.

In the manual this is said that the default parameters are preconfigured like:
• Red Eth: 192.168.5.1/24
• Yellow Eth: 192.168.6.1/24
• USB 192.168.2.1/24
• WiFi 192.168.3.1/24
• Bluetooth 192.168.4.1/24 (according to version)

Two problems, I think, prevent file and printer sharing. Firstly normal domain browsing over routers is not allowed in windows unless you install a WINS server or add the addresses to the LMHOSTS file (see http://support.microsoft.com/kb/q150800/).

The second problem was that the firewall in Windows XP allows printer- and file sharing by default only in the same subnet. This can be edited in the firewall settings I changed the setting tot custom by setting the value to "192.168.0.0/255.255.0.0", which means all subnets within the 192.168.x.y network.

I forgot to mention that I stopped the DHPC server on the router and gave my computers in the network (the same) static ip adress

You'll need to assign different IP addresses to different machines on the same network. There is a parallel to mailing addresses. If you're shipping something from an address, and the destination address is the same, how do you get there?

The WINS setup you're talking about, NetBIOS over TCP/IP, is only necessary if you want to find machines by their name, such as \\computername. You'll still be able to find the different machines by IP address if File and Print Sharing are configured properly. You would enter the two slashes into your browser, followed by the IP, like this: \\192.168.5.11

I noticed this thread has seen quite a number of page views and would therefore warrant posting some material I have uncovered over the months:

The manufacturer's website can be found here (http://lgsagem.free.fr/drivers_fast3202.htm).

The manufacturer's reference manual can be found here (http://lgsagem.free.fr/Telechargement/DriverFast3202/Documentation/SAGEM%20FAST%203202%20(livebox)%20ENGLISH.pdf)

The procedure for port forwarding can be found here (http://www.portforward.com/english/routers/port_forwarding/Sagem/Livebox-Fast-3202/BitTornado.htm)

Drivers for wireless cards on Linux machines connecting to the Live box can be found here (http://ndiswrapper.sourceforge.net/)

Most forums on this particular modem are either in Dutch or French. From what I have read, I can make out that using the modem as a router is generally discouraged because it hasn't been designed as a router.

Hope this helps
