Natting is only permissible inbound as part of publishing rules - outbound ISA ALWAYS uses the first ip address bound to its external nic - that cannot be changed.
In publishing, when you select the listening interfaces, you will see the Addresses tab - once there are more than on IP address assigned to the external nic, you can select the addresses tab and pick the individual Ip you want to use. the publishing rule asks the internal Ip address you want to move the traffic to (exchange, web, sharepoint etc).

ahh ok i think i know what you mean, what about port forwarding?

There is no difference. In ISA terms, port forwarding is the process of using one address and then using numerous ports and forwarding them sepeartely. NATting is for when you have multiple addresses and so you will have more than one instance of a port. For example, you may have two web servers with different domains both on port 80. in normal forwarding you would have one listen on port 80 and the second on maybe port 81 - you would then forward the ports internal to port 80 on each server (ISA does link and port translatioon also - maybe this is what you are meaning by forwarding?). With multiple Ip addresses you can listen for TWO port 80's - one on each address

Create a new protocol called ticketing or something using tcp port 4545 to tcp port 4545 - do this from the toolbox on the right (new - protocol) when you have highlighted the firewall policy on the left hand side.
create a new computer object in the same way and give it the ip address of 232.232.23.23 or whatever its real ip address is

Create a new publishing rule and select non-web service, allow and select the protocol you have made. When asked, give the 192.168.0.1 address when asked where to listen, select external and follow the instructions above. the users will be the computer object you created. just make sure you have also allowed 4545 through your external router to ISA.
