i agree with keith_alabaster and here is how to do it :
open control panel >> network connections>> local area connection 2 (external network) >> properties >> TCP/IP V4>> advanced >> then add the IPs as you want.

Not a fool at all - we have all been there ourselves at some time.
If you are new to ISA, you are unlikely to be aware of this little nugget either. It is worth understanding before you spend another bunch of hours struggling with when you have multiple IP addresses on the ISA external NIC,
Firstly, on outbound traffic, you cannot select which IP address ISA will use, it is set to use the FIRST ip address bound to the nic and cannot be changed. this is important for your mail/exchange system when you set your MX dns records.
Secondly, when you publish servers, ISA - by default - listens on all IP addresses for that traffic - so once you add a second ip you need to select the addresses you want. For example, lets say that you have one address of 10.10.10.10 on the external nic and you have published an internal rdp server on port 3389 on the external ISA nic to the outside world. - all great and works fine. You now decide to publish a second internal rdp server on port 3389 and want to do so on a second ip address. The first thing you have to do after you have added the second ip address to the nic in the OS is to EDIT your existing rules.
Double click the first rdp rule and edit the properties. Whereyou selected the 'external' nic to listen on, you will now see that the addresses tab is available. In here you can select which of the two now available IP addresses thais rule should listen on. Once done you can create the new rule to publish the second rdp server, use the addresses tab a second time and select the second ip address. Now you have two rdp rules, each bound to its own rdp server and listening on its own external ip address.
Repeat as required.

Simply add them to the external nic of the ISA server in the operating system network properties for the nic under tcpip - advanced settings
