I have been playing with network stuff so I installed GNS3 network simulator.

I have deployed ASA 8.4 image and it has loaded fine.

I connected it with basic Switch


I have configured IP address on an interface and executed no shut. I then tried to ping itself but ping did not work :(

I have restart GNS3 also but didn't work :(

interface GigabitEthernet0
 no nameif
 no security-level
 ip address

Trying to ping itself

fw01# ping
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to, timeout is 2 seconds:
No route to host

Success rate is 0 percent (0/1)

You need to set the interface name otherwise the interface will remain unreachable.


interface gi0
 nameif inside
 ip address
 no shutdown

To verify your interface status

show int ip brief
  • You also need a security level configured. Although most code versions will automatically set a security level of 0 for you once you set the name. Except if you set the name inside, in which case it sets a security level of 100.

I believe you also have a set a security level for the interfaces in an ASA. From what I remember, there's three things that need to be configured for each interface:
Name Security Level IP Address
