VirtualBox host-only network, ping works only from guest to host
This could be a firewall issue. The Windows 7 firewall blocks ICMP echo requests by default. Try to disable the firewall or to add an exception rule for ICMP echo requests.

I have a Windows 7 VM running on a Ubuntu 15.04 host using the latest Virtual Box 5 release. I've configured a host-only network. The configuration of the host-only adapter is:
Adapter IP 192.168.56.1 Subnetmask 255.255.255.0 DHCP enabled Server 192.168.56.100 Mask 255.255.255.0 from 192.168.56.101 to 192.168.56.254
With the adapter being created by VirtualBox,
ifconfig vboxnet0
displays:vboxnet0 Link encap:Ethernet HWaddr 0a:00:27:00:00:00 inet addr:192.168.56.1 Bcast:192.168.56.255 Mask:255.255.255.0 inet6 addr: fe80::800:27ff:fe00:0/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:960 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:0 (0.0 B) TX bytes:112330 (112.3 KB)
The Windows 7 guest receives an IP from the DHCP Server and also seem to have a properly configured interface:
Ethernet adapter Local Area Connection: Connection-specific DNS Suffix . : Link-local IPv6 Address . . . . . : fe80::18e1:2f8e:907a:e280%11 IPv4 Address. . . . . . . . . . . : 192.168.56.101 Subnet Mask . . . . . . . . . . . : 255.255.255.0 Default Gateway . . . . . . . . . :
The issue I'm currently facing is that I can ping the Ubuntu host from the Windows 7 guest using
ping 192.168.56.1
. However, I can't ping the guest usingping 192.168.56.101
from my host system. Wireshark tells me that echo requests are sent just fine, but there are no replies coming back. The guest system is a fresh installed Windows 7. -
Roper over 8 yearsThanks. Disabling the firewall actually solved the problem. I never thought that the Windows firewall would block a simple ping by default.
