  • Using VM Ware and GNS 3 for Internet access

    Hi,

    I m working on VMware server and installed on win 2003 server as a guest OS. Normally when trying to access internet from vmware guest OS it will access internet via host adapter to which it is connected. But what I did I divert this from normal process. I used GNS3. Used GNS3 router and on host I used 3 NIC. one is physical NIC and another virtual NIC provided by VMWARE and another one to which vmware guest nic is associated to. Can be understood by example:

    1) vmware win 2003 installed.
    2) vmware 1 guest VMNIC ip add 10.81.199.3/24 gateway 10.81.199.2/24 of GNS3 router.
    3)GNS3 router having NM-2FE card installed. Fa0/0 Ip add 172.19.27.2/24 and Fa0/1 10.81.199.2/24
    4)GNS3 router is now associated to host vmware NIC 172.19.27.1/24 and host vmnic 10.81.199.1/24.
    5)Done NAtting on Fa0/0 as ip nat outside and Fa0/1 ip nat inside.
    6)one physical nic 192.168.1.10/24 which is a doorway for internet.
    7) Now the point is here where traffic coming from vmware guest OS via GNS3 router. I am using Host OS WINxp.
    I add route for diverting traffic which was disturbed by host based vmnic to which vmware guest nic is associated. What i did, I added route like this:
    route add 10.81.199.3 mask 255.255.255.255 172.19.27.2
    It worked.Try to use arp -a ,also. note on xp ip forwarding is enabled.

    Internet is working on vmware guest os via GNS3. By this u can able to play not only with natting but also with nbar based qos. And many other features of cisco IOS.
