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

domestic hardware firewall?NetScreen Firewall is a pure hardware firewall, most of the domestic firewall is a combination of soft and hard firewall, not a pure hardware firewall. The NetScreen firewall uses ASIC chips to handle firewalls and VPN encryption, which is much faster than software programs that drive CPUs to achieve these functions.What is the difference between 20.Screen OS 3.1 and screen OS 3.0?Screen OS 3.1 differs from Screen OS 3.0 in

Problem description: When the SSG series firewalls of Juniper can access each other through VPN dial-in or direct mutual access between different network segments, sometimes PING can be reached, but the service cannot be accessed, such as WEB and shared files. Problem Analysis: These problems are often caused by the identification of data packet fragments by devices during data transmission. Generally, data packets are too large and nee

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
