The other lines are superfluous because they changed the access-list to care about the 'real' IP in the destination instead of the 'mapped' IP. You can see that line 4 is the only one that has ever had permitted hits from my RDP attempts.

Nat (outside,inside) static 10.20.30.40 service tcp 5000 5000However, it doesn't work. Object network object name real_port mapped_port]This one is easy, as it's not dns, the service uses tcp and the real port I want to use is 5000, mapped to 5000 on the internal ip address, so it should be service tcp 5000 5000.Īccess-group letstuffin in interface outside
To not get into issues, I wanted to look at the access lists later, so I decided to completely open the port on the ASA.Īccess-list letstuffin extended permit tcp any any eq 5000Īccess-group letstuffin in interface outsideOn 8.3, NAT is changed, it now requires network objects: Machines inside can access resources on the public Internet. Internal server tcp port: 5000Regular NAT is enabled and working. My objective: to get a port on my external IP address forwarded to a machine in my internal network so I can make connections to it when I am not connected to my home network but somewhere on the Internet.įor the sake of the example here, let's put numbers to different parts: So I went into the command reference to find out what i need to do with the access-list, access-group and nat commands. Then you need the access-list to actually allow traffic from outside to go through your new NAT setup:Īccess-list outside-allowed-in extended permit tcp any interface outside eq 5000Īccess-group outside-allowed-in in interface outsideīut unfortunately that didn't work. Nat (inside,outside) static interface service tcp 5000 5000
