Cannot ping/connect to guest from host, host-only
Cannot ping/connect to guest from host, host-only
Hello,
after an upgrade of VirtualBox (not current version, but previous one) I found that Host-Only adapter was deleted, so I just added it via Preferences -> Networks -> Host-Only networks. When I run the guest (Ubuntu 14.04), the IP of Host-Only network is right (192.168.56.101) but I am not able to connect to guest even ping that IP. But what is interesting, I am able to ping the IP of host (192.168.185.1) from guest. I tried to delete file /etc/udev/rules.d/70-persistent-net.rules as mentioned in topic which I cannot link now, but this file does not exist in my guest.
Hope I fill find finally solution here, thank you for any help.
The guest log file and output of VBoxManage showwminfo command are attached below.

Re: Cannot ping/connect to guest from host, host-only
post the ifconfig of the guest.

Re: Cannot ping/connect to guest from host, host-only
I would investigate a firewall issue.
Re: Cannot ping/connect to guest from host, host-only
Do you mean firewall on guest or host? On host I tried to add IP 192.168.56.101 to "always allow list" (I don't remember how it is called, I tried it few weeks later) but no effect then.

Re: Cannot ping/connect to guest from host, host-only
Since you have a one way link that works then you must assume that the pipe is valid. Only think that I can think of is a firewall issue or virtual software that restricts the LAN in some way. Temporarily disable the firewalls and virus software and see if it works. Then turn them on one at a time and see where it fails.
Re: Cannot ping/connect to guest from host, host-only
I've disabled firewall & antivirus on host, in Ubuntu I am not sure how (I don't have iptables installed) and still no change - cannot ping the guest.

Re: Cannot ping/connect to guest from host, host-only
Post the following from the hosts command window:
Note: you must be in the directory that has VBoxManage
Also in the guest, did you leave it set to DHCP or have you used static? If the latter change it to DHCP and test.
Code: Select all
VBoxManage list hostonlyifs

The second question, I am not quite sure, do you mean this (image in attachment, because I cannot send links yet)?

Re: Cannot ping/connect to guest from host, host-only
No I actually meant what I said. The way you configured the guest itself. Did you leave it set to DHCP or did you enter a static address?
Re: Cannot ping/connect to guest from host, host-only
In Ubuntu I have Automatic (DHCP) for IPv4 set for both Ethernet adapters. I wasn't setting IP manually in my guest.

Re: Cannot ping/connect to guest from host, host-only
You show IPAddress: 192.168.185.1 but the address of your DHCP is 192.168.56.100 ( 101-254) which will never work.
The default is 192.168.56.1 for the host-only. Double check that you have set it properly and make sure to cold boot the host.

Re: Cannot ping/connect to guest from host, host-only
Thank you so much!
The problem was here, it was set by default when I created this adapter, so changing the IPv4 address in Adapter tab (Preferences -> Network -> Host-Only Networks) to 192.168.56.1 finally fixed the issue. Thank you again.

+1. Thanks. Works for me.Perryg wrote:You show IPAddress: 192.168.185.1 but the address of your DHCP is 192.168.56.100 ( 101-254) which will never work.

Linux Mint Guest OSes use DHCP (10.0.5.100, 255.255.255.0, 10.0.5.101-254). Host is Windows Server 2008.
I changed the default IPv4 address of the adapter to 10.0.5.1 via Virtualbox manager > File > Preferences > Network > Host Only Adapters > Edit button.
Re: Cannot ping/connect to guest from host, host-only
I have the very same problem but I cannot go forward to solve it.
My data is the following:
Windows host: Ethernet 2: 192.168.56.1(this is on the host-only network adapter)
Windows guest: Ethernet 2 (Host-only interface): 192.168.56.101
I can ping from guest to host, but not from host to guest.
The DHCP server of the host is 192.168.56.100, the DHCP host range is from 192.168.56.101 to 192.168.56.254
This range seems to be OK.
What else do you need to solve this problem?
