Using SDM to allow access to internal servers

I need to know how to allow access to a server inside my network from the internet using SDM. I have a 837 router. I need traffic that comes in on port 8001 to go to ip address 192.168.1.1 on port 80. I know I need to use some combination of ACL and NAT to do this, but I don't know what should be in the access-list. How do I set up the NAT, and where do I apply it? I have a DSL connection and there is the ATM0 interface as well as a virtual Dialer1 interface.

I am familiar with PIX firewall. Basically, what I want to do is a static translation (if any ip comes in on port 8001, send it to 192.168.1.1 on port 80) which would be static (in, out) tcp [outstide-ip-address] 8001 192.168.1.1 www netmask 255.255.255.255

. How do I port this over to the router???
