Cisco ASA Port Forwarding Using Dynamic NAT

I understand NAT and I understand other routers.  Just not sure how these ASAs deal with Dynamic NAT. I have a Cisco ASA5505 and I need to forward SSL to an internal ip address.
I am already using 3 static NATs to other servers in my enviornment.  I have one IP address definded as my WAN interface and one definded for dynamic NAT for my other nodes on the network.  I only have 5 WAN IP Addresses. See below:

global (outside) 1 interface
global (outside) 1 [WANIPADDRESS #5] netmask 255.0.0.0
nat (inside) 1 192.168.70.0 255.255.255.0
nat (inside) 1 0.0.0.0 0.0.0.0
static (inside,outside) [WANIPADDRESS #2]  192.168.70.210 netmask 255.255.255.255
static (inside,outside) [WANIPADDRESS #3]  192.168.70.220 netmask 255.255.255.255
static (inside,outside) [WANIPADDRESS #4]  192.168.70.222 netmask 255.255.255.255
access-group inside_access_out in interface inside
access-group outside_access_in in interface outside

What I need to know is can I forward HTTPS to 192.168.70.3 for my [WANIPADDRESS #5]?  If so how?

Thaks for your assistance

Following line is the syntax for just doing individual ports (PAT rather then NAT)

static (inside,outside) tcp [WANIPADDRESS 5] 443 192.168.70.3 443 netmask 255.255.255.255

what BooSTid posted is the command for static and make sure you have :

access-list outside_access_in permit tcp any host [WANIPADDRESS 5] eq 443

another thing i noticed is you have:

global (outside) 1 interface
global (outside) 1 [WANIPADDRESS #5] netmask 255.0.0.0
nat (inside) 1 192.168.70.0 255.255.255.0
nat (inside) 1 0.0.0.0 0.0.0.0

i guess

nat (inside) 1 0.0.0.0 0.0.0.0
global (outside) 1 interface

should be sufficient for your other nodes considering 192.168.70.0 is your internal network.
so like that you get WANADDRESS#5 free for the static.
