Title
(EN) Protecting network devices by a firewall
Abstract
(EN)

Systems and methods provide for scaling and management of a gateway. In one embodiment, a method includes: in response to a request from a client device, establishing, by a computer system implementing a gateway to a private network, a network tunnel between the client device and the gateway; and after establishing the network tunnel, starting a separate firewall service with a separate set of firewall rules on the computer system for selectively blocking and allowing network traffic between the client device and one or more network devices in the private network.
