Networking - Can't ping other hosts

Hi Folks,

I've installed Arch as a VirtualBox guest and configured network to use dhcp according to the wiki. I can only ping localhost, pinging other hosts 100% packet loss. What am I missing?

TIA

* ping does not work with VirtualBox NAT networking

    VirtualBox's implementation of NAT networking is done entirely in user space. This means in particular that it has no way of passing on the ICMP IP packets which are used by the ping command from the guest, as these require special privileges to send from the host. The upshot of this is that you can't ping anything outside the local 10.0.2.x subnet from a NATed guest.

same thing if you want to connect to guest opertating system to different ports

p.s ping isn't a good benchmark to see if connection is working. try to query dns. nslookup google.com instead

Give what you have. To someone, it may be better than you dare to think.

Ahhhh..... What I couldn't understand is why, although ping fails, its still gives me the IP of the destination host. Now I know.

Thanks a lot!

Re: Networking - Can't ping other hosts

If you are interrested in it, there is a guide that i found helpful, wich explains how to use TUN/TAP networking instead of the NAT-solution.

I'll look into that. Thanks.
