Problem with DNS lookups (NAT)

Reported by: DragMZ Owned by:
Priority: major Component: network/NAT
Version: VirtualBox 4.1.8 Keywords: dns

Host type: other


NAT network adapter

Running the following shell script on a Debian VM causes DNS lookups to timeout after ~15s of execution


while [ 1 ]; do nslookup; done

The error is:

;; connection timed out; no servers could be reached

It doesn't occur with bridged adapter. It occurs on all network adapter types (i.e. Intel, PCnet, virtio-net) available in VirtualBox.

Tested on:

Windows 7 host - VirtualBox 4.1.6, 4.1.8

Debian host - VirtualBox 4.1.4

When the timeout occurs, the machine cannot resolve any domain for ~1 min.

This seems to work around the problem:

VBoxManage modifyvm "VM name" --natdnsproxy1 on
