The ASA does not allow ICMP echo by default. You can do it with an ACL or by turning on ICMP inspection.

Going by your diagram and your config PC1 is on the outside interface. For starters by default the asa blocks ALL traffic unless its told not to do so. I don't see any policies inspecting any traffic.

i.e:
policy-map global_policy
class inspection_default
inspect dns preset_dns_map
inspect ftp
inspect h323 h225
inspect h323 ras
inspect ip-options
inspect netbios
inspect rsh
inspect rtsp
inspect skinny
inspect esmtp
inspect sqlnet
inspect sunrpc
inspect tftp
inspect sip
inspect xdmcp
inspect icmp

You could also create a access list allowing that traffic in.

PC1 is on the outside interface you must look at it from a real world perspective. The outside interface would be pointing to the internet which means some computer on the internet can't just ping an internal host with a private ip address without specific rules allowing it to do so.

I also don't see a route or nat configured. In your exact setup you may have to setup static nat which will tie in PC2 to the address of the outside interface but that gets to complicated for a 'basic' config.

Google what you need to configure a basic configuration on a asa 5505 there are plenty of articles on it. You will learn how to properly configure it in the process because all you have configured is the password, asdm access and the ip addresses for the interfaces. Theres more that still needs to be configured on the ASA before it can be considered a "basic config".

Think of it this way if you were an electrician that was installing the power in a new house under construction all you did so far was install the outlets in the wall and light switches without running or connecting the cables going to the main and you are scratching your head wondering why when you try to turn on the light it doesn't work.

Good luck

Welp, so much for answering this thread..the real Security masters are all over it. MoP, shouldn't you be focusing on IPS and letting me come across as somewhat of a Security guy here? lol

I promise not to steal the spotlight anymore

I managed to arrange my schedule so that I can take the test tomorrow. I'll let you know how it goes.

Hi again

now I have another problem I can ping to the outside device but no to the outside interface of the asa? How this think can happen ?

When you find a solution to the problem you asked for assistance with its generally appreciated to share your answers with the group if you want additional help. Just a suggestion!

U can't ping outside interface from another interface network coz of asa architecture.

I don't know if it works on other ASAs, but on the 5505 there is a command to reset it to its original out of the box configuration. I use that as my base configuration and configure from there.
