The router (or ASA) giving different ports for a Dynamic PAT is what allow multiple hosts to share a single public IP address at the same time.
This answer will explain why a Dynamic PAT must change the Port number.
Either way, the ASA will allow you to configure two Static NAT's, but keep in mind the translation will only apply in the outbound direction. On the inbound direction, only one Static NAT will apply.
Meaning if you have two Internal hosts: 10.0.0.11 and 10.0.0.22, and you configure two Static NATs:
object network HOST1
host 10.0.0.11
nat (inside,outside) static 72.9.9.33
object network HOST2
host 10.0.0.22
nat (inside,outside) static 72.9.9.33
When either host makes a outbound request, their traffic will be translated to 72.9.9.33. BUT, if anyone external initiates a request to 72.9.9.33, it will only be translated to Host1's IP address.
So it isn't a true Static NAT. It's a true Static NAT for the first host (inbound and outbound), and a psuedo Static NAT for the second host (outbound only).
If you only need specific ports to access the internal servers, you're better off configuring a Static PAT.
10.10.10.1
is not a public IP address, it is in the10.0.0.0/8
Private IPv4 address block.192.0.2.0/24
,198.51.100.0/24
, and203.0.113.0/24
. That way people know you are giving an example, not that you are completely confused about public/private addressing.
