Replying to NTP requests from a Virtual Server IP

Hi, I am trying to configure the F5 to function as a NTP server, but through a virtual server instead of a self IP. The KB only has information about setting it up on a self IP. Is this possible? ...

Big-IP as NTP server - DevCentral (f5.com)

may be useful... In the above use case, it's a Performance (layer 4), UDP virtual server with Pool created consisting of NTP servers. If things don't work, try toggling "Port translation", SNAT= Automap, and take tcpdumps at the BIG-IP and NTP servers to verify requests are reaching. Hope it works out.

Good stuff.. but unfortunately not quite the use case I'm looking for.

Due to the security requirements of our environment the NTP servers are unreachable from the data plane of the F5. So the goal was to hopefully have the F5 sync up to our stratum1 servers via the management interface, then service requests from clients via a VS.

Is there a way to have the F5 process NTP requests from a VS or to redirect requests from into the VS into a self IP?
