    Having trouble getting ASDM working on my GNS3..


      Hi all,


      I have a problem using the ASDM for my ASA setup on GNS3. I am fairly new to GNS3 and CCNA security and trying to get ASA working so I can practice while studying. Here's what I have done so far..


      I have setup GNS3 0.8.5 on my windows 8 laptop. Also setup the ASA 8.4 firewall okay.


      Then I configured a loopback ethernet interface on my Windows machine and successfully conneted it to the ASA as shown on the image below.

      I can ping the host from ASA and the host can ping GiEthernet 0 interface(it's gateway, as shown above) without any problem.


      Then I uploaded adsm-713.bin to the ASA using tftp from my windows machine. It was okay too:

      ciscoasa# sh flash:

      I have setup the http server as well, giving what I think is adequate permission for the client(my windows machine) to connect via web-browser. But I cannot seem to connect via a web-browser. The ping seems fine. I even put wireshark on my loopback interface, and I can see that the pings are answered by the ASA but it's ignoring all the SYN requests to the ASA:



      Here's is my running confing. Anything I seem to have missed or done wrong?..
