howto connect a speedtouch dsl lan modem with a hub so two computers can connect to the web?

                                                                                   bs"d

I'm a newbie in networking, so maybe someone here can help me.

I have an Alcatel SpeedTouch Home adsl modem with a 10 Base T connection to a WinXP Home edition pc for internet access.  I live in Israel where they use a VPN with hard coded ip numbers in the network setup to connect to the web.  I also have an 8 port Power Traf hub.

I want to connect my XP home machine through the hub so I can share the web with another computer at the same time.  A friend told me it is possible to do, but you need to program the alcatel modem somehow to do it  -- a friend of his, who works for the phone company set his up.  

Being a newbie in networking I need to know how to do the cabling between the computers, hub, and modem also.  :-)

Thanks.

if this is actually a VPN, you will need a router capable of being the VPN end point. otherwise if its a normal dsl and the alcatel is not a router, you will need a router to act as the static ip endpoint your isp gave you and it will create an internal network for your pc's to share / translate to the internet.

program the router by logging on to the default web page (usually the gateway address in your network configuration) ... so you have to check what IP you are getting by going into network connections, and lan adapter properties .. double clicking on TCPIP.. [or goto start/run type 'cmd' and enter...then type 'ipconfig /all' and see the ip configuration there]

once you have your gateway, goto your web browser and put the gateway in there... and enter.. you will get a id/password screen... which you should have documentation with the router about that- enter id/pw and configure the static info the isp gave you... or call the ISP.. they should be able to assist you in configuring the static IP as well.

I can login into the modem / router using the ip 10.0.0.138 -- it doesn't ask for a id/pw, and I get a whole 'website' of Alcatel setup pages - initail setup, system setup, routing, bridge, dhcp, ....  I don't know what to do from here though.  The local service provider (the phone company provides the connection to the isp's, who are independent) is singularly unhelpful as to how to program the modem/router unless you happen to know someone there who will help. :-)

ok so we are on the same page - what version alatel do you have?

http://www.speedtouchdsl.com/support.htm

you want to make sure that there is a dhcp server on, and NAT (network address translation) is also on. if your internet is working , then you only need to do those 2 things.

then plug a patchcord (ethernet) cable into the hub and connect to the LAN of the modem, also plug a cable into the pc's to the hub, and you should be good to go.

let me know what happens and the model # of the modem.

hi there

what i sould suggest is follow craigs instructions apart from that buy one additional lan card and place it in the computer with the internet access. try to give the ip address 192.168.1.1 to that particular network card and then connect that to the hub/switch.  give 192.168.1.XXX and gate way as 192.168.1.1 to all the other computer which want to share the internet.

this should help. if ur assigning ip address manually u dont need a dhcp server. u need to enable internet connection sharing in the computer connecting to internet which will take care of the NAT network address translation.

Hello Craig,

I apparently have the Speed Touch Home / Home for ISDN modem listed under discontinued models on the Alcatel support page -- the manual is http://www.speedtouchdsl.com/pdf/sthome_manual_04.pdf .

It looks simple in the manual to set up a network - just plug the pc's into the hub and the hub to the modem (pg. 19).  When I tried this, my desktop works ok.  The green lights on the 2nd pc and hub light up.  However the 2nd pc can access only the modem at 10.0.0.138.  The second pc is configured exactly the same as the first. If I put in a ip address from the web, I get a 'cannot find server' error message. I can turn on 'auto DHCP' in the modem, however, the help there says NAT is only supported in the Pro version, not the Home modem.  Is there a way to do this without NAT?  

I don't have an extra slot available in the desktop for another LAN card.

Which connection method are you using? The manual suggests PPTP is VPN.

It sounds like you need the modem to be the end PC and then the router part of the modem to share the connection via the hub. From what you have said so far you still have a connection direct to your PC.

Does PC connect to the web if you have PC1 disconnected?

if it does not have NAT, can you get a router and use it instead of the HUB in order to share the connection with the second PC. ?

just to make sure that its not some config preventing you access on the 2nd pc, can you shut off pc 1 and reboot (release/renew your IP)?? and does it get on then? if not then you may be looking at something on the 2nd pc preventing you access....like a firewall, antivirus sw... or something else.

the speedtouch home is not a router. You need to upgrade it to the pro firmware. Search the web on how to hack it.
The other alternative is to put it into bridge mode, and use a separate router behind it. A router usually includes a multiport switch which allows you to eliminate the hub.

Ok -

I found a web site that gives step by step info on upgrading the firmware to Pro for use with the local isp's.  

http://www.petri.co.il/upgrade_from_alcatel_speedtouch_home_to_pro.htm

I'll try it and get back -- it looks like it should work.

Hi - it works!

One minor problem still.  What do I do with the old VPN connection?  It still pops up occasionally and asks to connect  (which it doesn't do anyway now that I've changed the modem settings).

A second question -- can I (and how do I) share files and printers via the new ip/tcp connection via the hub/router/modem  -- or should I open a new question to ask this one?

My feeling is that the points for this question should be split between public and Craig -- is that ok?

Thanks.

delete the vpn connection from within internet explorer == tools/internet options / connections tab.. or check that box says never dial

open up a new question for the other one.... more people will jump in
