SmartView Tracker logs show that DCE-RPC traffic on High Ports is dropped, although a rule with the ALL_DCE_RPC service exists.
Dropped traffic:
DCE-RPC
WMI
SCCM
Cause
Possible reasons:
The DCE-RPC traffic is matched to a rule that allows traffic on TCP port 135 or TCP port 111 and located above the rule with the "ALL_DCE_RPC" service.
The RPC initiator (traffic on TCP port 135 or TCP port 111) must pass through the Security Gateway on the "ALL_DCE_RPC", so the session "real" traffic on the higher port will pass.
