Asa Firewall Add default Route ASDM

We will discuss how to add a default route in the Cisco ASA firewall using ASDM. Using default route entry we can enable internet access for the LAN users. 

We assume that our gateway address is 2.2.2.2 that is provided by our internet connection service provider. Now we will add the default gateway or default route information. If the firewall not found any routing information for the specific network in its own routing table, then it will forward that network traffic via default route or default gateway.

We will go through the step-by-step process using ASDM. At first log in to your firewall using ASDM. Then go to the "Configuration" tab and click on the "Device Setup" button from the left panel.

Now expand the "Routing" tree from the "Device Setup" configuration list. Then click on the "Static Routes". Now click the "Add" button to add the default route.

Now select your outside interface from the "Interface" field. Here the outside interface means, the interface that is connected to your local ISP. I have selected the "outside" interface because this interface is connected to my local ISP. Write the destination network address in the "Network" field. Since I am setting the default gateway, so my destination network will be 0.0.0.0/0 or we can select "any4" from the "Network List" And finally, write the gateway address that is provided by your ISP. According to our scenario, our gateway address will be 2.2.2.2. Now click the "OK" button to close this window.

At last click on the "Apply" button so that the route entry will start work.

The default route entry process is done.
