Dynamic vs. Static IP -Internet Connection/File sharing

Hi
I have a number of PCs on a small peer-to-peer network. Each PC has a static
IP so that I can share resources over the network.

However, I have been keen to share an internet connection with some of these
PCs but if I remove the static IPs (as the Windows help files suggest) and
dynamically allocate IPs to each of these clients - will I still be able to
share resources over the network? When are these IPs allocated (when each
node connects to the network?)

My firewall has each of the static IP addresses defined presuming the IPs
are dynamically assigned in ascending order I can stipulate a range of IPs
for which the firewall sees as trusted nodes...???

One further thing, not all of these PCs should be able to use the Internet
connection - how do I prevent users from using this connection when it is
shared on the host computer short of removing all shortcuts to IE etc. on the
clinet PC???

Thank you for any help you can give.

Regards
Guy

It should not matter whether the IP addresses are assigned dynamically, or
whether they are static. Windows file sharing is based on the NetBIOS names
of the computers, and the network handles the process of locating shared
resources with ARP broadcasts. Or something like that.

Is it a firewall, or a router; they aren't quite the same thing. It is not
a function of a firewall to manage IP addresses.

OIC. You have one computer set up as an ICS gateway. That computer is,
functionally, a router. I don't know how I would do it with an ICS gateway
computer. I know how I would do it with a router.

Both static and dynamic IP addresses allow computers to share
resources over the network.

What firewall program do you have? Every firewall program that I've
seen lets you specify a range of trusted IP addresses, so you don't
have to specify individual computer addresses.

However, your desire to prevent some computers from accessing the
Internet might make static IP addresses the best choice.

When you enable Internet Connection Sharing on the host computer, it
automatically assigns IP address 192.168.0.1 to the host's local area
network connection. The host acts as the default gateway and DNS
server for the other computers.

You can assign static IP addresses to the other computers:

IP Address: 192.168.0.x (1<x<255)
Subnet Mask: 255.255.255.0
Default Gateway: 192.168.0.1
DNS Server = 192.168.0.1 or your ISP's DNS server

To prevent a computer from accessing the Internet, only give it an IP
address and subnet mask. Don't give it a default gateway or DNS
server address.
