What have you tried so far?

I haven't even looked at my Cisco setup in a long time, so I may be a little rusty, but maybe I can at least give you some ideas. :)

I use this on my 515's (which I believe is similar syntax to the 501):

static (www,outside) tcp aaa.aaa.aaa.aaa www 192.168.1.2 www netmask 255.255.255.255 0 0
(forwards tcp port 80 from outside to the inside "www" interface)

access-list outside permit tcp any host aaa.aaa.aaa.aaa eq www
(enable incoming port 80 to the outside IP)

ip address outside aaa.aaa.aaa.aaa 255.255.255.224
ip address www 192.168.1.2 255.255.255.0

nat (www) 1 0.0.0.0 0.0.0.0 0 0
(And this one I can't remember -- just telling it to nat that interface, I believe)

I hope that helps a little bit at least. :)
