I will be using the GUI and the CLI for each example (at least thats the plan). Summary. For example, on some models the hardware switch interface used for the local area network is called lan, while on other units it is called internal. So, yes if you have the proper nat in place between DMZ and inside (provided that nat-control is enabled) then you just need to apply the correct access list on the DMZ interface to allow web server to communicate with the internal SQL server. !

Hey guys..I would really like to thank Networkstraining.com for helping me nail down this thing. encryption aes (Assuming that I understand this correctly) If the dmz interface is on 192.168.10.x/24 subnet, the static NAT will look something like this; Now I ran into two separate problems with the Mgmt port IP assignment.

For such a communication to work, you need to have a Security Plus license for the ASA5505 firewall. Although practical QCs would pose a threat to crypto standards for public-key infrastructure (PKI) key exchange and encryption, no one has demonstrated a practical quantum computer yet.

You will need also to configure an access list which should be allowing traffic from outside to 100.100.100.6 on port 80.
