NAT network on Adapter not working on Windows GUEST

[jwithana]

I opened a new ticket as a follow on to #2286 due to the confusion.

I Cannot access the internet from Guest after upgrading from VB 2.0.0 to 2.0.2. In the Win Guest, the network shows as connected but no sites can be accessed by IE or Firefox. Firefox on the Ubuntu host works fine.

I tried to downgrade back to 2.0.0 but this still does not fix the issue.

Can you PLEASE tell me any tests you would like me to run on the UBUNTU HOST or WINDOWS GUEST and post the output?

[jwithana]

also, shared folders DOES work so i wonder if the whole networking is inoperational or just part of it?

[Frank Mehnert]

Shared folders and networking are two completely different subsystems. Please could you attach a VBox.log file of such a session?

[jwithana]

sure. where do i find this file?

[Frank Mehnert]

Please go to the VM selector window, select the VM, click on the 'Machine' menu and select 'Show log ...'.

Log file after upgrading to 2.0.4, problem still happens (no network on Win XP Guest)

[Frank Mehnert]

Please have a look at your log file. There are the following lines:

NAT: passing domain name local
NAT: DNS address: 192.168.1.1
NAT: ignored DNS address: 68.237.161.12  

Is 192.168.1.1 a valid name server? Or should the other one used?

[jwithana]

192.168.1.1 is the router so prob not a good name server.

how can i make it NOT ignore DNS address: 68.237.161.12 ?

Replying to frank:

[Frank Mehnert]

Currently VirtualBox supports exactly one DNS server which is read from /etc/resolv.conf so you have to make sure the correct IP address comes first.

[jwithana]

many thanks, that worked. DNS could be configured for a different primary fromt the GUI

was wondering if you would support 2 DNS servers in VBox in the future? or if it could be submitted to the suggestion box?

[Frank Mehnert]

Starting with version 2.2.0 VirtualBox passes multiple DNS servers to the guest. So your problem should be fixed. You also might want to have a look at section 9.14 (Enabling DNS proxy in NAT networking mode). Though enabling the DNS proxy is not required to get this work.
