Abstract
In one aspect, a computerized method includes the step of providing process monitor in a Gateway. The method includes the step of, with the process monitor, launching a Gateway. Daemon (GWD). The GWD runs a GWD process that implements a Network Address Translation (NAT) process. The NAT process includes receiving a set of data packets from one or more Edge devices and forwarding the set of data packets to a public Internet. The method includes the step of receiving another set of data packets from the public Internet and forwarding the other set of data packets to the one or more Edge devices. The method includes the step of launching a Network Address Translation daemon (NATD). The method includes the step of detecting that the GWD process is interrupted; moving the NAT process to the NATD.
