making a net from 1 ip

Hi, I have 3 computers connected to hub and the hub in its turn
connected to the internet using rj-45 cable. I have been told by
system admin that to use 192.168.3.48 as an ip address for one
computer and the gateway 192.168.3.1 and the submask is 255.255.255.0.
He told me to run DHCP on that computer so he can give other computers
dynamic IPs!!! I am confused?? how can I coonect the other computers
to the internet?! what should the sys admin should give me to make
these 3 computers work? I am running window 2000 prof on these 3
computers?? any help would be very much apprciated. Thanks

2000Pro doesn't have DHCP server built in asides from Internet connection
sharing. What does the hub connect to the internet through, an adsl router?
(presumably it has an IP of 192.168.3.1 from what you said?) If so, give the
3 machines addresses in the same range, i.e. one can be 48 as you said, the
others 49 and 50, same gateway and subnet. In theory that will work, but
hard to say without knowing a bit more.

Eh? I think basically your answer is assign the three PCs different IP
addresses. Although I'm not really sure what the question is so it
might not be.

You can't do that with a hub, you'd need a router. So I guess you're
actually connecting to a LAN

So presumably that's an address he's allocated to that machine on the
LAN

> and the gateway 192.168.3.1

and that will be the router that the LAN uses to connect to the Internet

(that's a subnet mask)

Running DHCP on _that_ computer won't enable him to allocate IP
addresses. I guess he wants you to run DHCP clients on the other
machines so that a DHCP server on the LAN can allocate their addresses.

Why doesn't the sysadmin come round and set it up himself - that's what
sysadmins do, surely?

Set up one computer with the IP 192.168.3.48, and gateway of 192.168.3.1 on
the interface with the other LAN. This machine will be a router for YOUR
machines. You will need two LAN cards in this machine. Plug one LAN card
DIRECTLY into the rj45 for the other LAN (internet). The other will go to a
hub, which plugs into your other machines.On the other interface card, put
an IP of 10.10.0.1

On the other machines, set IPs of 10.10.0.2, 10.10.0.3 etc, with gateway of
10.10.0.1

This should then set the other clients to route through your computer to the
internet. I suspect there may be another step involved here but I can't
remember it since I haven't used Win 2000 in a long time!

--------------------
BUT..................
--------------------

The much easier case is get the sys admin to give you more IPs for the other
machines, then you just need to set the IPs on those machines to the ones
he gives you, with a gateway of 192.168.3.1 and then just set up as below:


----PC 1
HUB ----PC 2
----PC 3
----'internet' cable

Hope this helps
