I have two VirtualBox VMs running. Both are running CentOS. The first VM has 4 NICs that are bonded to together. All four NICs are using Host-Only for their config. The second VM has one NIC that is set to use NAT. Let me preface this by saying, I haven't setup any routes... Why am I able to ping from second VM (10.0.2.15) to the first VM (192.168.56.101) successfully? The routes for the second VM are as follows: Destination Gateway Genmask Flags MSS Window irtt Iface 10.0.2.0 * 255.255.255.0 U 0 0 0 eth0 link-local * 255.255.0.0 U 0 0 0 eth0 default 10.0.2.2 0.0.0.0 UG 0. 0 0 eth0 Thanks for your help in advance!
