help: need to have W98 with two IP Address

[jmm]

I've one PC (windows98SE) with :
- usb port: -> modem -> nternet.
- network card: -> intern lan.

When I configure the IP Adresse, name, etc... of the network card, I
don't see anything with ipconfig (all are 0.0.0.0) because... the modem
on the usb port becomes an IP Address from internet provider.
So, I couldn't running the Internet connection + my intern lan.

That's a big problem and I've these questions:
1° It's possible with (windows98SE) to have one IP Address on usb port
and one other IP Address on the network card, without a second network card?
2° Could running a router software with NAT on windows98SE? if yes,
what're software to do that?
3° Are they other possibilities, other ideas????

Best regards,
jmm

This is not true. See, IP Address is assigned to the interface not
to the computer. Since you have 2 interfaces, modem and network card
you can assign 2 IP addresses.

What I see is that you are incorrectly assigning the IP Address to the
network card. Go to Properties of LAN and assign in TCP/IP Settings.

Also make sure that you don't assign the IP Address to the modem connection.
Set it to receive automatically that is DHCP.

Then paste here the contents of *ipconfig /all*

That's a big problem and I've these questions:
1° It's possible with (windows98SE) to have one IP Address on usb port
and one other IP Address on the network card, without a second
network card?

As said, there are 2 interfaces so 2 IP addresses can be assigned. But the
IP
addresses of your internet connection is usually determined at connection
time
i.e. when modem dials to server , it receives the IP addresses(DHCP).

2° Could running a router software with NAT on

windows98SE? if yes,
what're software to do that?

No need.

3° Are they other possibilities, other ideas????

Already mentioned.

Could you please tells me explain more about this config, because I've
assign the TCP/IP adapter for my network card and then...

OK, Since you are using win98, go to network control panel, Select the entry
which looks like this TCP/IP->Ethernet Adapter and set the IP address as
192.168.0.1 and mask as 255.255.255.0. Do the same for another machine
but give the IP as 192.168.0.2. Do not enable DNS and do not set any
gateways.

...ipconfig /all tells me ethernet 0 ip 0.0.0.0 ???

If you have successfully completed the above setup, then it should show the
IP address as 192.168.0.1. Please paste the contents of this command here.
Also run the command *winipcfg* and see that it doesnt show the status as
*cable disconnected*.

Could I really use NAT on W98?

Why do you want to use NAT. NAT is basically used for Internet sharing
within a LAN.

Apart from the answers you already have, is there a reason you need to
manually assign an IP address to the network card?? I used to run 2 x 98SE
machines, one also with modem, and the system assigned the IP addresses in
all cases... The modem was always the ISP assigned IP address, and the
network card would be assigned an IP address IF it needed one - i.e. if
there was no connection to the network card, there would be no IP address
assigned.

Is this what your problem is? Is there anything connected to the LAN? If
not, then that's why the ethernet hasn't got an IP address (and it doesn't
need one).

So, my 98SE machine has a connection thru modem (usb port) with Internet
(the ISP assigned IP address) and a network card connected with other
PC's thru a switch, that it!
When I put the command ipconfig /all I see the IP address from the ISP
because he take the TCP/IP drivers and not my other IP address.
I'd like to have two live connection, one to Internet, the second to the
intern LAN and both IP addres in two different subnet

I think that's not running with 98SE!!!? Perhaps do you have any better
idea ?

....this too!

Yeah, because I'll use two differents IP subnet (ISP + LAN) and I don't
want that other guys in Internet know my own IP subnet and address from
my Intern LAN

Does the network card have TCP/IP protocol installed? Check in control
panel....

If you've just added the network card, try selecting Add new hardware and
that should then install what you need to get it all running. If you go to
the TCP/IP protocol of the NETWORK card, you can enter a static IP address
as others have said, but if there is no TCP/IP protocol installed for the
network card then that is your problem.

I'd like to have two live connection, one to Internet, the second to the
intern LAN and both IP addres in two different subnet

Yep, no problem, it will do that no worries, but by the sounds of it your
network card isn't fully installed properly - TCP/IP protocol needs to be
installed on that one as well as the internet connection, and the two
configure seperately.

OK - go to Control Panel then open up Network. Scroll down the list of
protocol's and services installed - you should find a TCP/IP entry for the
internet connection AND a second TCP/IP for the ethernet card. If not, then
there is your problem and you will need to either add TCP/IP protocol for
the ethernet card OR as I said above try Add New Hardware and install the
ethernet card again.

If you find the TCP/IP for the ethernet card, highlight it and select
Properties. This will then let you either configure Auto IP or specify IP
address. I find mine worked OK allocating it's own IP address, but you can
allocate if you want - as other said, try 192.168.0.1, subnet mask
255.255.255.0. Then make the other PC 192.168.0.2 with mask 255.255.255.0

I've always found 98SE to load all required software and protocols OK for
networking, but I have had to manually go to Add New Hardware and even
manually select the network card... after that all worked fine. Remember
with 98 to reboot after changing IP details, etc (it should prompt you).

Did any of that make sense??? What you are trying is very possible as I
have had the same config running in the past with 2 x 98SE machines. The
TCP/IP settings for the internet and LAN are seperate - and there should be
the two TCP/IP settings visible in the network settings...

Yeah, because I'll use two differents IP subnet (ISP + LAN) and I don't
want that other guys in Internet know my own IP subnet and address from my
Intern LAN

99% of home type LAN's use the same IP address anyway!!!

*Technically*, this statement has got no meaning. What do you mean by
/he take the TCP/IP drivers/. I have said again, that please exactly
paste here the contents of *ipconfig /all*.

I'd like to have two live connection, one to Internet, the second to
the intern LAN and both IP addres in two different subnet

I have the same configuration as yours and its working for years without. Do
not use the term subnet. subnet exists in the same networks while your modem
and the LAN network are completely different networks.

I think that's not running with 98SE!!!? Perhaps do you have any
better idea ?

This is completely incorrect. They are completely different networks and
no one from outside will able to peek into your LAN network. Be sure, not
to enable services like File sharing on the modem network.

You tells me that is completely incorrect! Do you known something about
routing, networking and so on?
When you send a packet from one network to Internet thru your ISP, your
origin IP Address travelled to Internet. NAT is using to hide your
origin IP Address. With the routing technologies we have the
possibilities to known all IP Address in Internet (I means, all IP
Address not protected by Firewall and NAT).

Sure, I am a computer Engineer and have studied networking.

When you send a packet from one network to Internet thru your ISP,
your origin IP Address travelled to Internet.

This is where you are mistaken. When you send a packet from your lan network
to the internet. The source of the packet will not contain your LAN IP like
192.168.0.1 but instead the IP which is used by the computer for connecting
to
the Internet. This technique is performed by the Network Address
Translation(NAT).
This is not a technique to hide the local network address , but NAT is there
since
this is the only way to access Internet from the local LAN.

This is because if the packet will contain source address as
192.168.0.1(which is a class
C address), upon reaching to the Internet, the internet will try to send the
destination
packet to 192.168.0.1, however the address 192.168.0.1 is only local to your
LAN and not to
the Internet(since it doesnt uses class C addresses). Thus the packet wont
reach its destination
and you will not be able to connect to the internet.

NAT is using to hide
your origin IP Address. With the routing technologies we have the
possibilities to known all IP Address in Internet (I means, all IP
Address not protected by Firewall and NAT).

Read a few sites on NAT, or post here if you need more information.

It's what I means too! The internet see the IP address from the computer
connecting to Internet and not from the IP LAN, because this address
was translate thru NAT. What I had defined by the word "hide"

right, but If you enable IP routing in your last gateway connecting to
the Internet and disable NAT. Then your internal LAN address will be
known (propagated) by the Internet and it will be confused with the
others same IP address (official one)! Do you understand what I means?
It's why I spoke to use NAT...

I think that we speak the same thing...

My question is how to use NAT with W98SE an how to use (active) it
between the two IP address (modem + ethernet)? Is NAT still active in
W98SE? I feel myself better with unix/linux it's why I put these
questions about W98SE!

Win98SE has built in Internet Connection Sharing(ICS) which you can use
for sharing the Internet. You can install it from Add Remove Programs.
However ICS provides very basic functionality. You can also use third party
windows rograms :
