The following NAT rule statically maps the DMZ 172.16.1.10 webserver address to the 148.12.56.68 external address. Configure inbound NAT rule for 172.16.1.10 DMZ webserver access The source interface name is replaced by the DMZ named interface. The same configuration as for the LAN subnet is done for the DMZ servers subnet. Configure NAT to allow DMZ servers to access the INTERNET The name of each interface, configured with nameif, is used in the AutoNAT command : nat (inside,outside) dynamic interface object network LANĢ. In each of these objects, a dynamic nat rule is configured to conduct Port Address Translation (PAT) on these clients as they pass from the inside to the outside interface. AutoNAT suits best if the ASA external IP changes frequently (DHCP).ĪutoNAT configuration for the LAN subnet is done by creating a network object representing each LAN subnet. Network Address Translation makes the addresses so that they look like the ASA's outside interface IP address. Network Address Translation is needed because these internal hosts use private IP addresses which are not routable on the Internet. In this lab, the AutoNAT feature of ASA 5506-X firewall is used to configure the NAT rules that allow the hosts on the LAN segments to connect to the Internet. Configure NAT to allow LAN users to access the INTERNET
