Just a basic check....
Is your ADSL Router operating in NAT mode right now?
If you are to make use of these additional IP Addresses you will need to
use your router in Non-NAT mode.
The First Usuable IP address in the range is normally assigned to your
router, you can use any of the other IP Address you wish for you ISA Server's
External Network Card.
Eg. (ISP)----------1st public IP(ADSL Router in Non
NAT)unassigned----------2nd public IP(ISA Server)--------(LAN)
When the ADSL router is configured in Non-NAT Mode the first public IP in
your range is normally given to the router.
The DSL Side of the router is normally operating in whats known as "IP
Unnumbered to Ethernet 0"
which basically means it shares the same ip address as the Etherenet Port.
The Ethernet port is allocated the first usuable address in your range.
You would connect this directly to your ISA Server or via a hub/switch. The
ISA Server external NIC then requires an ip address from your allocated range
in the same subnet.
Hope this gives you a bit of an insight in to what you need to do to use
these extra addresses.

Rules.... create inbound rules and the outbound rules.... from the inbound
rules you can assign a static IP to an inbound internat private ip address...

Hello,
Our proxy server is running Windows 2000 server with ISA Server standard
edition. We use Alcatel Speed Touch home ADSL modem for internet connection.
It's plugged in to the ISA server network interface through its Ethernet cable.
VPN connection is established to the ADSL modem from ISA computer. Our Internet
provider assigned us one public IP address that appears like WAN (PPP/SLIP)
Interface after connection is established. We need more addresses. Our provider
said that it has assigned 10 IP addresses for our line. We asked how we should
configure our modem that our external users will be able to use these
addresses. It's said that we should only configure our Windows 2000 server that
hosts ISA server. We tried to ping that addresses from Internet but without
success.
Does anybody know how to configure our Server or modem such way that we will be
able to use that external IP addresses for Server's publishing in the ISA
server? We want the following scheme: one external address corresponds to one
internal address.
Thanks in advance,
Michael
