Hi,
I have problem to create static NAT between public IP address range (ie. 222.222.222.2 - 222.222.222.6) and private IP address range (192.168.101.2 - 192.168.101.6). When I try to ping the PC (192.168.101.2) in my private network from the public network (ping 222.222.222.2) or vice versa nothing happend. The "debug nat" command shows the following error message: nat: untranslation - outside0:222.222.222.2/0 to inside0/3:192.168.101.2/0.
Here is my configuration:

Solved! Go to Solution.

Your config is right, there is something else that is happening.
Try packet tracer
packet-tracer input outside icmp host
And see what the ASA will do with the packet.
Also use
capture capin interface inside0/3 match icmp host
capture capout interface outside match icmp host
sh cap capin
show cap capout
to capture packets and see if they are sent.
I hope it helps.

Please remove the following lines as there is no need for them:
access-list Traffic_in extended permit ip any 222 222.222.2.255.255.255.248
object network MAPPED_JULKINEN
nat (outside0,inside0/3) static MAPPED_INSIDE
(actually removing the network object should also remove the nat statement)
Once you have done this, you may have to do "clear local-host" , "clear xlate" .
Then try again.

Thank you for the answer! Unfornately it did not help me. I removed unnecessary lines from my configurartion but the NAT not works. Below is my current configuration:

Hi,
Thanks for your help! I used the command "packet-tracer input outside icmp host
There was also another mistake in command " nat (inside0/3,outside0) static MAPPED_OUTSIDE" because I use subinterface "TAC-verkko". So the right command is " nat (TAC-verkko,outside0) static MAPPED_OUTSIDE.
