I need to remote control machines located on Private Network "A"
(14.x.x.x) from a machine located on Private Network "B" (172.x.x.x).
Addresses on "A" are NAT'd. I have no problems when connecting via the
User object, however, when I attempt to connect via the Workstation
object the connection times-out.

Ports are open.
I have selected Accept connections across NAT in the policy.

Any suggestions?
