When synchronizing data across computer rooms, VPN links are often used because of the high security. Online on this aspect of the article, I really did not find that I want, is too simple, Daniel do not want to write it, or too difficult to do it?The following example illustrates the establishment and use of VPN links
First, install the VPN server on the remote

Execute commands on ngfw_a and ngfw_b on the display IPSec policy [brief | name Policy-name [seq-number | extend-acl]] to see if IPSec security policy is applied on the correct interface.
11.SA Timeout configured too small
If the user disconnects frequently, the reason may be that the IKE SA time-out is configured too small. The IKE SA timeout period defaults to 86,400 s
value is 86400, which is the day. It is worth noting that routers at both ends have to set the same SA cycle, or the VPN will arrive in a shorter SA cycle after the normal initialization.

This article provides a comprehensive explanation of LAN networking. During VPN networking for small and medium-sized enterprises, we will encounter many setup problems, here we will introduce you to a configuration scheme for setting up a VPN Server in a LAN, which is illustrated in detail throughout the networking process.
Next I will use Win2000 on the
Step 1 of Cisco ASA firewall VPN configuration: Create an address pool. To remotely access the client, you need to assign an IP address during logon. Therefore, we also need to create a DHCP address pool for these clients. However, if you have a DHCP server, you can also use a DHCP server. QUANMA-T (config) # ip local pool vpnpool 192.168.10.100-192.168.10.199 mask 255.255.255.0 Step 2: Create IKE Phase 1.
The VPN configuration of the Cisco router is not important for network security, but also makes the user more convenient during use. In this experiment, we use the Cisco 2600 router and the Cisco router VPN configuration to implement the blue campus. The networks between the first branch and the second branch are inter
Question:Most firewalls or UTM deployment modes include the routing mode, the bridge mode, and the hybrid mode. The core configuration is the write rule, A good rule will greatly improve the security of the internal network. Of course, if UTM is used, other security components may be attached. For example, the most common rule is the AV anti-virus component, IPS components, anti-spam components, and some other components such as

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.
