Question

I have two Virtual Machines on VMBox, I am configuring and connecting these machines. I set the two interfaces to each machine with NAT and Internal, also, IP addresses are set. While when I ping "test1" 192.168.1.2 and ping ubuntu with "192.168.1.1", it both shows destination host unreachable. How to fix it? PLease

buntu@ubuntu-desktop:-$ ip addr 1: lo: <LOOPBACK, UP, LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group defaul E qlen 1000 link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 scope host lo valid_ift forever preferred_ift forever ineto ::1/128 scope host valid_ift forever preferred_ift forever : enpos3: <BROADCAST , MULTICAST , UP, LOWER_UP> mtu 1500 qdisc fq_codel state UP gr up default qlen 1000 link/ether 08:00:27:99:40:e8 brd ff:ff:ff:ff:ff:ff inet 10.0.2.15/24 brd 10.0.2.255 scope global dynamic noprefixroute enpos3 valid_lft 71637sec preferred_lft 71637sec inet6 fe80::f5e0:f9b9:6d4f:f910764 scope link noprefixroute valid_lft forever preferred_ift forever 3: enpos8: <BROADCAST , MULTICAST, UP, LOWER_UP> mtu 1500 qdisc fq_codel state UP gr up default qlen 1000 link/ether 08:00:27:fc:c3: fo brd ff:ff:ff:ff:ff:ff inet 192.168.1.1/24 brd 192.168.1.255 scope global enpos8 valid_ift forever preferred_ift forever inet6 fe80::a00:27ff:fefc:c3f0/64 scope link valid lft forever preferred lft forever

Answer 1

I believe there is issue with IP 192.168.1.1 in most of the cases it is the default gateway address so I would suggest take another IP address available like 192.168.1.5 to 192.168.1.10 make sure it is available.

Second in network section add new NIC briged network or host only network on each VM

Lubuntu - Settings X General Network System Display Adapter 1 Adapter 2 Adapter 3 Adapter 4 Enable Network Adapter Attached to: Host-only Adapter Name: VirtualBox Host-Only Ethernet Adapter Advanced Storage Audio Network Serial Ports USB Shared Folders User Interface OK Cancel

Then try to ping it will be reachable.

If you still have any issue then you can also remove the static IP and let the VM get the IP from DHCP server.

Please do comment if you have any issue.
