Asa 5506 version 9.5

[patrickernane]

Good afternoon, I have an ASA 5506 I'm having difficulty redirecting the public ip 200,188,213,171 ----> to get the IP address at 172.18.37.11:8080 that our Cameras nvr and get external access in the browser by typing;
Http://200.188.213.171:8080 Help?

Hello,

You will need a NAT for translation, example:

object network NVR-172.18.37.11
   nat (inside,outside) static 200.188.213.171 service tcp 8080 8080

[patrickernane]

I tried this setting but it gives me an error  

FW001(config-network-object)# nat (inside,outside) static 200.188.213.171 ser$
ERROR: empty object/object-group(s) detected. NAT Policy is not downloaded

[visco]

Sorry, the network object will need to be created first:

object network NVR-172.18.37.11

     host 172.18.37.11

Then add the NAT. 

You may also need to add an entry on your ACL that is applied to the outside interface to allow the traffic in from the outside. Are you wanting to allow it from anywhere, or lock it down to a specific Public IP? Do you have an existing ACL applied to the outside interface?

run the command:

show run access-group

Is there an ACL applied to the outside interface?

ERROR: empty object/object-group(s) detected. NAT Policy is not downloaded

I created the object but when I go to add nat it generates an error is not downloade

You do not have the access group 

[visco]

It looks like the network object is still not created, it says its empty. Do this first:

object network NVR-172.18.37.11
       host 172.18.37.11

After that host entry is added in the network object, you can add the NAT

[patrickernane]

You experienced the same error.

This is the start configuration show run of the wing

ERROR: NAT Policy is not downloaded

Also there is no in-use NAT entry for this IP...

fw-01(config)# sh nat 200.188.213.171 detail

No matching NAT policy found

[visco]

Thanks for the config. See if the following works:

object network NVR-172.18.37.11
nat (inside,outside) static interface service tcp 8080 8080

[patrickernane]

Now there was no error

Your add the line

Access-list NVR1 allow tcp any host 172.18.37.11 eq 8080 8080

It will be possible to access from a browser http://200.188.213.171:8080

[patrickernane]

It tested but did not open login screen without browser

Access-list NVR1 allow tcp any host 172.18.37.11 eq 8080

n my internal network this ip 172.18.37.11:8080 is of the NVR and I want to access defora here in not typing in the browser http://200.188.213.171:8080

[visco]

Have to apply your new NVR1 ACL to access-group on outside interface now:

access-group NVR1 in interface outside

[patrickernane]

Sorry, I do not understand, can you add me an example please?

[visco]

conf t

access-group NVR1 in interface outside

[patrickernane]

Ah I added this line but it did not work
