ASA1(config)# object network INSIDE
ASA1(config-network-object)# subnet 192.168.1.0 255.255.255.0
ASA1(config-network-object)# nat (INSIDE,OUTSIDE) dynamic 192.168.2.253
this tells our firewall to translate traffic from the 192.168.1.0 /24 subnet headed towards the OUTSIDE to IP address 192.168.2.253. If you configure the IP address like this then it has to be an IP address that is not in use on the interface. For example, when I try to use 192.168.2.254 (that’s the IP address on the OUTSIDE interface) then I will get an error
Hi Rene,
Can you please explain from the above statement if 192.168.2.253 is INSIDE GLOBAL OR DESTINATION IP in the packet that is sourced from INSIDE?
