Networking configuration problem

[pappin]

Hello everyone,

I am trying to test a small network inside Virtualbox (4.2.12 r84980)

I have installed VirtualBox on a windows 7 (sp1) laptop with wireless internet access via a Broadcom 4322AG 802.11

a/b/g Wi-Fi adapter and Wireless Modem/Router with ip 192.168.0.1.

I have set up 2 windows 2003 servers (sp1) and a windows xp (sp3) client in VirtualBox

============================
2003 Server 1

Domain controller DNS & DHCP server

1 network adapter

NETWORK ADAPTER SETTINGS
Internal Network
intnet
Promiscuous Mode - Allow VMs
Static ip 192.168.1.1
Mask 255.255.255.0
Gateway 192.168.1.2

============================
2003 Server 2

2 network adapters

NETWORK ADAPTER 1 SETTINGS
Internal Network
intnet
Promiscuous Mode - Allow VMs
Static ip 192.168.1.2
Mask 255.255.255.0
Gateway 192.168.0.150

NETWORK ADAPTER 2 SETTINGS
Bridged Adapter
Broadcom 4322AG 802.11 a/b/g Wi-Fi adapter
Promiscuous Mode - Allow All
Static ip 192.168.0.150
Mask 255.255.255.0
Gateway 192.168.0.1 -- modem/router

============================

I can ping all the virtual machines on the internal network from each other.

I can ping the modem/router (192.168.0.1) from 2003 Server 2 and I have internet access from 2003 Server 2.

I can ping the second adapter on 2003 Server 2 (192.168.0.150) from any of the virtual machines.

I can't get internet access or ping the modem/router (192.168.0.1) from any of the other virtual machines on the

network.

Can anyone advise me what I have done wrong.

Thanks very much

Please try the same setup but connecting with cabled connection, not with Wifi.

If it still doesn't work :
Run the following on your host for each VM name :

Code: Select all

vboxmanage showvminfo VmNameHere --details

and on the host and in each VM :

Code: Select all

ipconfig /all
route print
arp -a

Also include the ping you talk about in your post.

Attach as a zip file the complete outputs.

Have you configured RRAS/NAT on the second server to route domain traffic to the Internet? Have you modified the DNS server on the DC to forward to a public DNS service so that it can resolve foreign URLs for domain users? (The domain users should use the local DNS only).

Hello and thanks for the reply,

Tried the cable connection without success.

I have uploaded the zip file

Thanks again for your help,

Hello noteirak,

Just realised after I posted my last that I changed the static ip address of the second adapter in windows server 2 to 192.168.0.151. It was 192.168.0.150 in my original post.

Thanks,

Hello BillG,

Thanks for your reply.

I had already configured the DNS server.

At the moment I am just trying to ping my modem/router from within the virtualbox network

As I said in my first post I can ping the modem/router Gateway 192.168.0.1 and external public ip addresses from server 2 but not from any of the other virtual servers or workstations.

Thanks

Hello again BillG,

You were right - I hadn't configured RRAS/NAT correctly. - Could kick myself !!

Thanks very much for your post
