Today to a customer in the Juniper SSG140 firewall debugging L2TP VPN, when established, the client asked me to establish 350 L2TP VPN users above the firewall, immediately dumbfounded, if manually set up 350 L2TP VPN users that will not be exhausted! A small program was written specifically to generate the L2TP VPN user command (pictured below) for the user's needs. With this applet, you need to fill in the relevant parameters, such as how many us

How to back up configuration files for Cisco, ruijie, And Juniper Devices For a company of a certain scale, network device configuration file backup is also a task that cannot be ignored, to prevent one day after your network device fails, you can recover in the shortest time, reduces losses for the company. The following describes the backup operations for several devices: I. Specific ideas: 1. Download ftp software and TFTP Software 2. Configure the

Obtain Juniper Netscreen webshells in batches using Censys Censys is a new search engine used to search information about networked devices. Security Experts can use it to evaluate the security of their solutions, hackers can use it as a powerful tool to detect attack targets and collect target information in the early stage. Its functionality is very similar to the popular Shodan, but its advantage over Shodan is that it is a free search engine, ini

The L2TP tunnel (L2TP tunnel) refers to the logical link between the second-tier Tunneling Protocol (L2TP) endpoints: LAC (L2TP access aggregator) and LNS (L2TP network server). When LNS is a server, LAC is the initiator of the tunnel and waits for the new tunnel. Once a tunnel is established, the new communication between this point will be two-way. In order to be useful to the network, high-level protocols such as Point-to-Point Protocol (PPP) are then passed through the L2TP tunnel. Today, j

To ensure the high availability of network applications, two firewall devices of the same model can be deployed at the edge of the network to be protected during the deployment of Juniper firewall to implement HA configuration. Juniper firewall provides three high-availability application configuration modes: master-slave mode, master-master mode, and dual-master redundancy mode. Here, we only describe the
