Any suggestions

firewall since windows update?

Hi Perryg,

Thanks for a reply; the firewall settings are the same on the host and router as before, I have tried to turn off the firewall but still had same issue.

Something is blocking it. One way pings are only caused by firewalls, which included the ability to use ICMP, which Windows usually shuts down.
Some virus software also trap ICMP.

What you need to ask yourself is what changed, what was installed.

Tonight, I can uninstall the McAfee to see what happens, but I installed virtualbox and created the VM's with the McAfee already installed.

OK but you said it did work and now it does not. If McAfee was already installed then it should not be the cause. I would really check that ICMP was still allowed first if it were me.

Or better yet set a rule for it http://www.sysprobs.com/enable-ping-reply-windows-7

Actually that was not the issue due to I have the microsoft firewall turned on and have McAfee firewall, I uninstalled virtualbox and re-installed and now able to ping the host from VM's. Perryg, thanks for your help

Ah then it really was a firewall issue. When you removed and re-installed VirtualBox Win will re-register it.
Look the firewall can be off and ICMP will not work unless it has been allowed. VirtualBox does not control this at any level is uses a simple hook to the hosts Nic drivers and lets the host deal with it.

In any regards it is working so case closed.

Perryg, thanks.

i have the same situation "cannot ping host" but i have firewall enabled on both guest and host.
Both host and guest is on windows.

Which side to check first, guest firewall? or the host firewall?

btw i checked both and all protocols, ports, IPs and programs are allowed for both inward and outward on both sides for host-only-network 10.0.0.1 (host) and 10.0.0.2(guest).

Hit and trial makes it work, by diagnosing network problem, enabling disabling Virtualbox-hostonly-network adapters and couple of restarts.

Problem is that i still unable to figure out why ping does not work from guest to host and what really makes it work?

second why host always ping guest without any issue while firewall rules look ok to me?

I have to fix the same problem every time i run VM. The guest Vm is for webserver which do need network at startup without issues. Please help me to get rid of this issue.

Locking.
