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
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 "
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
Today, we will demonstrate how the Juniper SRX Firewall runs ipsec vpn + OSPF with Cisco routers.
Topology:

R1 simulates a cisco device, which is equivalent to a branch site. R2 simulates a carrier device, C1 is a zhuyun device, and bridging with SRX, which is equivalent to a firewa
Real juniper devices are expensive, so we use simulators to simulate juniper routers and juniper srx firewalls. The topology is simple:
Juniper router em0.0 ------------ VM1----------------SRX ge0/0/0.0
That is to say, the first network adapter of
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, t
When a network fault occurs, how to quickly locate the fault point is a basic indicator for evaluating the capabilities of a network administrator. Today, I will share with you how to quickly locate vpn Router faults and provide some ideas for you to solve network faults. I take the cisco vpn Router as an example here.
Turn on the VPN service on the router, where we can access resources on the home network and easily and securely access data from the home network. The following will show you how to open the router VPN service.
Using the router's DMZ (quarantine) settings or applications using networked storage, we are able to access
This article describes the VPN technology in detail from the specific concepts, solutions for different users, as well as its interfaces and implementation functions.
VPN is short for Virtual Private Network.
As the name suggests, we can regard a virtual private network as an internal private line of an enterprise. It can establish a proprietary communication line between two or more enterprise intranets co
mpls vpn model consists of three components: CE, PE, and P:CECustomer Edge): It is a user's network Edge device. interfaces are directly connected to service providers, such as routers or switches. CE "perceives" that the VPN does not exist.PEProvider Edge) vro: the operator's Edge router. It is the Edge device of the operator's network and is directly connected
simply impossible, because MPLSVPN is completely isolated from different customers. The third misunderstanding is that MPLSVPN is vulnerable to external DoS attacks. This is also wrong. The pure MPLSVPN network is extremely secure. If the supplier's edge router only provides VPN access and the MPLS core that provides Internet access, it can effectively prevent DoS attacks. Another common problem is that ev
Currently, there are many users who use VPN routers. It is essential for users to set up valid VPN routers. Here we will give you a detailed explanation. We know that traditional routers do not have the proxy routing function. As Vpn proxy technology has become popular over the past few years, many people want to use VPN
As a widely used access network method, the technology of the ADSL Router is very mature. Next we will give you a detailed analysis on how to perform VPN connection. Virtual Private Network (VPN) is an extension of a Private Network. It contains Internet-like shared or public Network connections. Through VPN, data can
It takes many attempts to eliminate the router VPN fault in a moment. The following is a reply from a netizen. I hope you can give it a try. It is a common method to help fans. Take the opportunity to provide it to you.

Nowadays, with the popularization and development of the Internet, mpls vpn technology is becoming more and more popular. mpls vpn is a type of MPLS Multiprotocol Label Switching Based Multi-Protocol Label Switching) the technical ip vpn is to use MPLS technology on network routes and exchange devices to simplify the route selection method of the core
After using the router, the LAN computer can access the Internet normally, but cannot connect to the VPN. As follows:
To troubleshoot this problem, follow these instructions:
Remove the router, the computer is connected to broadband VPN dial-up, if a stand-alone network
With the development of VPN Router technology, Linksys VPN Router has become the best choice for small and medium enterprises, which also promotes the upgrade of VPN routing technology. Currently, enterprise networking is a professional
In fact, the VPN settings of the D-link router are very similar to those of other route VPN settings. Next we will explain the configuration steps of using the DLINK router to establish a point-to-point VPN, in the following article, we will take the most common method of st
