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

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

First, Juniper Open SNMP The steps to turn on SNMP are the same as yesterday's reference to configuration methods, which is skipped here.Second, install the configuration MRTG 1, installation MRTG's official page is http://oss.oetiker.ch/mrtg/, the latest version is 2.17.4. You can choose to compile the installation using the source package, or you can select the system source installation. The code is as follows Copy Code

Experimental environment: Company game online, need to build a VPN channel for authentication and billing system for different areas of internal communications, as well as daily maintenance server is also through VPN connection. To achieve a secure encrypted environment Solution: Using juniper netscreen SSG140-SB automatic VPN function to solve this problem, because to set up a lot of points, setting almost all the same, to Shanghai room and Changch

1 Juniper Router enters configuration mode for the first time, you must set the login password, or the commit prompts for a root-authentication password, and the login password method is set as follows: Root#set system Root-authentication Plain-text-password New Password: (the password here must be a combination of numbers + letters, at least 6 digits) Retype new Password: After the setup is complete, the root login password is set successfully.

First connect to Juniper NetScreen via web ssg140 Expand Configuration > Date/time sequentially First sync your PC with network NTP, so that it's relatively close to our hypothetical NTP server time, and then click the Sync Clock with Client button. A message prompts you to specify whether the daylight saving time option is enabled on the computer clock. Click Yes to synchronize the system clock, adjust the system clock according to daylight s
