A network management (NM) computing system generates a first work zone associated with a first remote network and a second work zone associated with a second remote network. Each work zone includes a respective virtual firewall and a respective virtual jump host. The NM computing system establishes a first and second communication path between the first virtual jump host and the first remote network via a multiprotocol layer switching network system, receives a data packet including a firewall identifier associated with the first virtual firewall and a local address associated with a destination device within the first remote network, routes the data packet through the first firewall to the first virtual jump host based on the firewall identifier, and transmits, by the first virtual jump host, the data packet to the first remote network using the first communication path and/or the second communication path.
