From a 3rd Party company there is a Fibre link terminating into interface
GigabitEthernet0/2 – RR_VLAB – 192.168.#.100/24.

The IP Address of the 3rd party is 192.168.#.5/24

The 3rd Party is connecting to network 192.168.#.100/24 on interface
GigabitEthernet0/2 – RR_VLAB to interface
GigabitEthernet0/3 – DMZ_QUICK – 10.0.#.1/24 to access the server 0n IP 10.0.#.2

The 3rd Party is coming into network on interface GigabitEthernet0/2 using these IP Network
addresses :

10.121.67.64 255.255.255.192
10.253.119.251 255.255.255.255
160.50.100.0 255.255.255.0

We need to translate the incoming network address from the 3rd party to a private routable address from
within the network within the RR_VLAB interface network address.

All traffic from the 3rd party to get to the server on the internal network on IP 10.0.#.2 will have their
destination address NaTed to 192.168.#.101 and further translated to IP 10.0.#.2 of the internal server.

Here is the ASA Configuration :
interface GigabitEthernet0/3
 nameif DMZ_QUICK
 security-level 30
 ip address 10.0.#.1 255.255.255.0
!
interface GigabitEthernet0/2
 nameif RR_VLAB
 security-level 10
 ip address 192.168.#.100 255.255.255.0
!

Static Nat Translation :
static (DMZ_QUICK,RR_VLAB) 192.168.#.101 10.0.#.2 netmask 255.255.255.255
!

Routing Table :
S    10.121.67.64 255.255.255.192 [1/0] via 192.168.#.5, RR_VLAB
S    10.253.119.251 255.255.255.255 [1/0] via 192.168.#.5, RR_VLAB
S    160.50.100.0 255.255.255.0 [1/0] via 192.168.#.5, RR_VLAB
C    192.168.#.0 255.255.255.0 is directly connected, RR_VLAB

 

Note : No reverse static NAT translation is configured here. This only applies to 1 way traffic.
