Good day,
I would like your help regarding my simple topology. Here it is below:
I was trying out my failover by shutting down interfaces and seeing if an automatic failover occurs. All is working but one. When I shut down the Gi0/24 of the L3 switch and the Gi0/1 of the Primary/Active ASA going to the ISP, I am no longer able to access the Internet.
My goal is that when I shut these interfaces, the OUTSIDE interface of the STANDBY ASA should take over, knowing that the OUTSIDE interface of the PRIMARY/ACTIVE ASA is no longer reachable. However, I am unable to achieve this task as all the traffic is still being sent to the PRIMARY/ACTIVE ASA and is still routing the traffic to its own outside interface, even though it is down.
Here is my configuration below:
interface GigabitEthernet0/0
nameif outside

Thanks for your reply. So to solve this issue, I would need to configure Active/Active Instead?

I have tried configuring this on my ASA, sadly same outcome.
