Methods, systems, and computer readable media for receiving a clock synchronization message

Methods, systems, and computer readable media for receiving a clock synchronization message are disclosed. According to one exemplary method, the method occurs at a first node configured to operate on a protected side of a firewall device. The method includes sending, via the firewall device and to a second node configured to operate on a non-protected side of the firewall device, a clock lease message indicating an amount of time for clock synchronization, wherein the clock lease message triggers the firewall device to allow a clock synchronization message from the second node to the first node. The method also includes receiving, via the firewall device and from the second node, the clock synchronization message.
