How to setup full NAT

liug
I am trying to setup a full NAT, eg: internal 192.168.1.5, outside 1.2.3.4

The GUI isn't very clear. 

Traffic Source: (when I setup SNAT, I need to put internal address here. When I setup DNAT, I put "Any" here. What to do with full NAT?)

Traffic Service: (Again, is this for the outbound traffic, or inbound?)

Traffic Destination: 

Nat mode: full nat

Destination:
Destination Service:

    So, FULL-NAT could kinda be considered as a FULL "spoof"..? Whatever matches the top section, the entire TCP header gets reset to whatever is in the bottom section.

    So, to make my 13 public IPs directly correspond to my 13 private IPs for ALL ports(TCP/UDP/ICMP,etc) I will need:

     13 DNATs saying Any,Any,Public ---> (Destination) Private, 

    and                                                                (one for each)

    13 SNATs saying Private,Any,Any ---> (Source) Public 



    Is that the gist of it?
