Multiple IP assignment

[Guest]

Hello friends,

My problem is a little different from the ones that have been queried by
others. Here it goes:

My ISP has provided me with a block of 8 IP addresses for my use. (As per my
understanding I can use 6 as the lowest and the highest aer reserved)
I have to Map my ISP Router with a different IP.

I have 7 systems to be connected to the Internet all are WIN XP Pro.
1 of these I have config to have ICS (yes it has 2 NIC one for external
network and other for internal)

I tried adding all IP given to me by the ISP in the advanced settings of
TCP/IP protocols. But lost connectivity between external and internal
networks. (Yes Internet connectivity is working fine on the so called server)
so i removed the same.
I am connected with my external network through a LAN extender XDSL modem.
and have a Linksys Switch for internal connectivity.

If more info is needed please do not hesitate to tell me!

May I request you good people to help me out.

Thank you for your time in advance!

ICS is a software based NAT router. A NAT router lets you use one external IP
address to run an entire LAN. ICS will require you to use the 192.168.0/24
subnet for your LAN, not the public IP addresses.

If you have multiple addresses, and multiple computers, all that you need to do
is to attach the Linksys switch to the DSL modem, and assign each computer a
fixed IP address. BUT please secure your computers if you do this. If you're
going to be running a LAN, with all computers attached directly to the Internet
(thru a switch is the same as direct connection), do not use NetBT based file
sharing (the default) - use IPX/SPX.

OK, if you don't want to buy a router (and that's your decision) then please use
IPX/SPX for file sharing. You'll need a firewall on each computer, but there's
no way that you can open a firewall, to allow file sharing between the
computers, and not share everything with the Internet in general.
