Explanation:
https://docs.microsoft.com/en-us/azure/log-analytics/log-analytics-oms-gateway
OMS Log Analytics Forwarder = OMS Gateway
If your IT security policies do not allow computers on your network to connect to the Internet, such as point of
sale (POS) devices, or servers supporting IT services,
but you need to connect them to OMS to manage and monitor them, they can be configured to communicate
directly with the OMS Gateway (previous called “OMS
Log Analytics Fowarder”) to receive configuration and forward data on their behalf.
