ASAv not pingable in GNS3

Hi,

I have created a basic scenario on GNS3 with ASAv and a PC but there I am troubling in ping issue from PC to ASAv or vice-versa. I am attaching ASAv configuration

Further, for troubleshooting I have tried to capute the packets and in that FCS is incorrect message is showing up.

Attaching the screen shots for your reference.

Please help to resolve this issue..

I ran into a similar issue, but you are not going to believe what the solution is:

Check that out and let me know.

Basically what it does state is that the Gig0/0 in the GUI is not the actual Gig 0/0 on the Firewall. The gig 0/0 is actually the management interface.

Right now, if you connect gig0/1 it will work, cuz the mapping for gig0/1 on the GUI is the actual gig0/0 on the firewall you configured.

Hi Maykol,

Again I tried the same thing what you have suggested but still having the
same issue.

Hi,

After so many efforts now got the solution on it.

and it was very surprising to me that after downgrading the GNS3 to version 1.4.6 all things are working fine.

Thanks.

It's just because the dismatch of the interface' type - one's gigabitEthernet and another(the PC) is Ethernet.

Thank you Maykol, it works。My GNS3 version is 2.2.35.1, ASAv version is 9.18(2)5.

I even could't believe that, is this probably GNS3's bug that the port gig0/0 on ASAv in GNS'3 GUI is actually management0/0?
