[Vpn-help] DNS Proxy daemon blocks VM DNS requests

I installed the 2.1-beta-5 which supports the import of pcf files on my Windows 2008 Enterprise server x64 with Hyper-V.
The client worked fine to connect to a cisco gateway from thVe server.
But I noticed after the install that my VM could no longer resolve dns requests on the external virtual adapter.
I ran wireshark on my DNS server (separate machine DC01)  and could not see any DNS requests from the VM but did see traffic from the VM requesting browser notifications.
I had put the domain controller in LMHosts and hosts file.
I stopped the Shrew DNS proxy and the VM can now resolve DNS requests from the VM. The Hyper-V server had no problem resolving DNS.
