[SOLVED] Virtualbox Guest Internet Access not working

[manuleka]

I've just installed VirtualBox 4.1.18 on LinuxMint 13 Cinnamon x64 and installed a Guest Windows 7 Ultimate x64 but the internet connection isn't working on the Guest

The network card is left on default which is NAT... help please

[oobetimer]

Did you reboot after the installation?

[manuleka]

yes... also reboot after installing guest additions

If you haven't done so, try setting the network settings to "Bridged Mode", not "NAT". Then, set it to eth0 or eth1, whichever is being used to connect to the Internet.

so is newbie to do with New User? or New to LinuxMint in experience?

I have used LinuxMint before then rolled back to Windows... Now i'm back and still with minimal experience hence posting in Newbie section

thank you so much... that fixed the problem... so i'm wondering why this is so? I remember running virtualbox on Windows and by default i get internet connection on NAT

I don't know either why NAT doesn't work with the latest VirtualBox. NAT used to work for me, too, but when it didn't work this time, I found that Bridged Mode let me connect to the Internet.

it's a version issue i guess... I've just installed the Ubuntu Software Center version on Xubuntu 12.04 which is Virtualbox 4.1.12 and NAT works perfectly fine... although i haven't installed this version on LinuxMint 13 (Which is the default version on Software Center) i think it is a version 4.1.18 (latest) issue

I posted this reply the first time a week ago, but it seems it never showed up.

The problem with NAT (at least for me) was that the vm machines weren't getting their DNS assigned from Virtualbox's DHCP service. The clients got IP's and routes, they just never got DNS. I suspect it has something to do with Mint now using the resolvconf package instead of using a standard resolv.conf file in /etc. I haven't taken time to confirm that suspicion.

However, the good news was that NAT works just great if I manually set my clients to use a DNS server of 10.0.2.2, the default IP gateway for the Virtualbox NAT.

Hope this helps.
