I am using LinuxMint17 (Host) and running another LinuxMint17 as Guest using Virtual Box.

My Guest LinuxMint is able to ping Host LinuxMint but vice-versa is not happening.

Network Setting in VirtualBox Network Adapter 1 - Host-Only Network (This i did so that Guest IP is aligned with Host) Network Adapter 2- NAT (To get my internet work on guest)

Can anyone suggest what i am doing wrong?

What set the IP of the eth0 interface on the guest? It doesn't look right; the IP's should both be in the same subnet.

Try (on the guest, as root):

ip addr del 192.168.56.103/24 dev eth0
ip addr add 192.168.50.2/24 dev eth0

That will delete the existing IP address, and add one that is in the same subnet.

  • @user1158351 Ah ok. I wasn't sure if the restriction applied to answers to your own post. – BenjiWiebe Jul 7 '14 at 17:34
