Note: Even though HTTP is also enabled on the Web Server, doesn’t work for some reason. We can confirm this by opening an HTTPS connection from the ‘Inside User’ to the ‘Web Server’: Since the inside interface is on a higher security interface than the dmz, traffic from the inside to the dmz will be allowed by default.
Notice the word “ initiate” in that sentence? It means that even though the dmz VLAN cannot initiate traffic to the inside, the inside VLAN can actually initiate traffic to the dmz and the dmz will respond. In that lab, we restricted the dmz VLAN from initiating a connection to the inside VLAN. it will only be able to initiate a connection to only one other VLAN.
In the last lab, we said that due to the license that comes with the Cisco ASA in Packet Tracer (Base License), the 3 rd VLAN we created (dmz) will be a restricted VLAN, i.e. To test this configuration, we will ping the 8.8.8.8 IP address from the Cisco ASA:
However, this short form is not (yet) implemented in Packet Tracer so we must specify it in its full form. This interface name specifies the interface through which the next hop IP address is reachable.įinally, instead of specifying “0.0.0.0 0.0.0.0” like we do on the Cisco IOS, we can shorten it to “0 0” on the Cisco ASA. inside, outside) for any route statement. The route command, used to configure static/default routes on the Cisco ASA, is an example of this.Īnother thing to keep in mind with the Cisco ASA is that you must specify an interface name (e.g. interface Loopback0Īs I said in the last article, many commands that have “ip” in the Cisco IOS do not have “ip” in the Cisco ASA. The goal of this task is just to simulate an external host, e.g. Create a local user on the ASA to be used for authentication with the following credentials: Username – “insideuser” and Password – “userpwd”. Enable SSH access to the ASA from any IP address on both the inside and outside interfaces.
