IP Forwarding to DMZ

Hello everybody

I have a quick question I hope somebody could answer. I have assigned two IP-adresses to the external NIC. Lets call them 10.10.10.1 (main) and 10.10.10.2. What I would like to accomplish is to forward all traffic that goes to address 10.10.10.2 to the internal IP 192.168.1.10 (example).

I know this can be done on port level with RRAS, but I cannot find how to do it on address level.
