juniper next generation firewall

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-availabili

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

The next generation of firewall wins the application layer, and the next generation wins the application layer. Why is next-generation firewall superior to application layer? Almost no one doubts about the important position of firewalls in the procurement of all security e

How to compare and select next-generation Firewall The security situation is changing every day. For example, changes within an enterprise include how applications are securely used and communicated. Although from the availability perspective, this change is a benefit in many cases. However, if improperly handled, it may also become a disaster for information security personnel. To cope with this change, E
