Dear Richard,
Thanks a lot for your answer!
I don't know anything about NAT in this modem. I suspect that it doesn't
support NAT. It's home modem for small company.
Its current configuration is following:
ISA server has 2 Ethernet interfaces - one for LAN (for instance,
10.x.x.x/8), the second is for ADSL modem Ethernet cable (it's connected
directly to the ISA computer - 172.16.0.1). VPN is established from ISA
computer to the 172.16.0.138 - ADSL modem.
So, as I understood you recommend to change all 172.16.0.x addresses to
the public addresses that our provider assigned for us?
Thanks,
Michael

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
