Routing back to Direct Access Clients - is this possible?

Hi,

We have been using direct access for the past few months successfully, however the one problem we are still having is we can't use programs that require a route back to the Direct Access client (such as managing a Hyper-V machine on the local lan), using SourceOffsite or even using Remote Desktop to remote onto a direct access client or ping the direct access client.

Our local LAN uses Ipv4 and we can route fine to the Direct Access clients from the Direct Access Server where the tunnel terminates but not from any other machine on the network. Do I need to change the direct access configuration to allow this or do I need to somehow create a route on my LAN for the direct access clients?

Thanks in advance

David
