network between multiple VirtualBox machines for my Mac

Hello
how can I connect the internet to the client machine in VM?
I am trying out to connect between two machines. the fedora  virtual machine which is the server and the ubuntu virtual machine which is the client.
the server has two adapters one is NAT and the another is internet network.
the client has one adapter that is internet network. Both has the same name of internet network in the adapter.

I am using Mac host mashine
Mac Ip 10.0.1.39

Fiest, Fedora virtual machine is connecting to the internet by using NAT:
ip 10.0.2.15/24
route 10.0.2.2
DNS 10.0.1.1
and in anther adapter using internet network has
ip 10.10.10.110/24
route 10.0.2.15
DNS 10.0.1.1

Ubuntu virtual machine
in adapter using internet network has
ip 10.10.10.112/24
route 10.10.10.110
DNS 10.0.1.1

it is pining between each virtual machines. fedora can connect to the internet but Ubuntu doesn't connect to the internet.
Can anyone help me out here?
how can I connect ubuntu as a client to the internet through using fedora as a server?
Thanks

use Bridged Networking Mode for ALL VMs.

IF Fedora got a new IP Address, that was from your DHCP server on you main LAN.

can you ping 158.152.1.222 ?

how was the fedora VM accessing the internet before?

do you use different IP Address and default gateway, than DHCP server gives out?

PCANWAuthor Commented:
fedora accessed the internet when it used NAT adapter. no it is not different because it got it automatic DHCP.

Andrew Hancock (VMware vExpert / EE MVE^2)VMware and Virtualization ConsultantCommented:
if it was using NAT it would received an IP Address DHCP from the NAT services, which then uses the Host networking to reach the internet.

Does the Host computer receive it's IP address from your LAN DHCP server, or does it use different IP address details than your DHCP server on your LAN

the host computer connects and receive the ip address from a wireless access point  (WLAN). it doesn't use different ip address. on Bridged Networking Mode used Wi-Fi.

Andrew Hancock (VMware vExpert / EE MVE^2)VMware and Virtualization ConsultantCommented:
so the IP Address received by the Fedora PC, is in the same sub network, as the host, when using Bridged Mode?

yes the same sub network as the host...

Do i have to use USB Wireless adapters/ card for Bridged Mode?

I meant different USB Wireless adapters/ card for Bridged

Andrew Hancock (VMware vExpert / EE MVE^2)VMware and Virtualization ConsultantCommented:
Now, I hate to have to mention this, but it would appear that WiFi devices behave different with the desktop hypervisors Virtualbox and VMware, and behave differently to fixed LAN cards, and cause issues. I suspect this could be the issue with your Bridged Mode.

When in Bridged Mode, the VM Network Interface should obtain exactly the same network information as the host, if the host works on the internet, so should the VM, it has the same mask, default gateway and DNS settings from the same DHCP/DNS server. The only difference is it has a different IP Address - unless this is restricted.

if this is true, bridging is not working correctly.

if you are using a WiFI device this behaviour is to be expected.

Hello
NowI have extra a wireless card for VirtualBox.  I changed the ip addresses I have some problems and I have mansion here
On VirtualBox, there is 2 OS. One is a fedora server and another is an Ubuntu client.
Fedora has 2 NIC one is external wireless, another is as Ethernet which is internal: adapter to internal network and Promiscuous mode allow all  
From fedora: When I ping to the client, it is pinging but when I ping to yahoo.com it don’t ping shows me “Destination Host Unreachable”
However when I disable the internal card, it is pinging to yahoo.com

I changed the file sysctl.conf as net.ipv4.ip_forward=1
# iptables -A FORWARD -i eth1 -j ACCEPT
# iptables -A FORWARD -o eth1 -j ACCEPT

Fedora
External ip 10.0.1.30/24
DNS & Getway 10.0.1.1
Internal ip 192.168.1.1/24
Getway 10.0.1.30
Clinet 192.168.1.2/24 getway 192.168.1.2
Please any idea.
