I am still having this issue running 13.1.0.2, in my situation the vs is running in a non-default route domain.

 

F5 confirmed we are dealing with bug ID 623036 - Native RDP proxy does not work if Virtual Server is in non-default route domain and CMP enabled. This bug is linked to bug ID6 17929 Support non-default route domains when connecting to other tmm over backplane.

 

Unfortunately no fix is available yet.
