Firewalls are often deployed on the edge of our network environment to isolate the network and protect the security of the Intranet and Internet. For example, in the edge network, MIP a public IP address to a VPN device on the Intranet, for the sake of security, EDGE networks need to have selective open ports or Protocols. MIP is as follows: 650) this. width = 650; "border =" 0 "alt =" "src =" http://www.bkjia.com/uploads/allimg/131227/0FP912P-0.jpg "/>

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
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
Juniper to implement the redistribution function like Cisco is to be implemented by policy, here is an example of me: its function is to distribute static routes to OSPF, the following is the topology map

It is undeniable that Juniper is a company with excellent technical capabilities and is highly competitive in the high-end router market. This is also the second company that I submitted my resume. It is also the most tortuous company in my interview experience. Haha, I don't believe it. It may take seven rounds for Juniper to interview, maybe more! Because I only went to the seventh round. @_@!First of all

Security Zone: The Juniper Firewall adds the concept of a new security zone (Security Zone), a logical structure that is a collection of multiple physical interfaces in the same property area. When communicating between different security zones, you must pass a predefined policy check to pass, and when you communicate in the same security zone, the default state allows for no policy checks and, if configured, enforces policy checks to improve security
