. The location where permanent routes are stored in the registry is. Pay attention to the red line of the last figure. It can also verify that the new commands will add static routes permanently. (Note the red line of the bottom picture) HKEY_LOCAL_MACHSYSTEM\CurrentControlSet\Services\Tcpip\Parameters\PersistentRoutes But in many cases, we only need to add routes temporarily? If this process is repeated, you can write a batch. Double-click it when necessary, For example, edit c: \ windows \ r

A debian system computer in our department is configured with a public network address: 202.96.x.x; to allow customers to connect to this computer from the public network. You can use ifconfig to view the tun0 device after each restart and cannot access the Internet. Use the command/etc/init. d/openvpn stop to disable tun0 and then access the internet. After each restar

Openvpn implements Security Based on OpenSSL, but it is not an sslvpn in the traditional sense. It is just a common VPN that works on the IP layer rather than the transport layer. VPN has two meanings: V, virtual, P, and private. Virtualization means that physical cabling is not required, and only one network is implemented logically. The reason why a virtual network can be implemented and established depends on the advantages of a layered model, the

If the software on your mobile phone is installed by the operator and mobile phone manufacturer, there is basically no security risk on the mobile phone (except for the mobile phone in the shanzhai factory ), in addition, the vendor also regularly releases patch packages for you to upgrade. Of course, the vulnerability fixing process is basically endless. By

At home, company seats, company meeting room, company corner, customer site, hotel... you have to configure your network card to ensure that it is consistent with the configuration of the location. This is too annoying! Is there a way to avoid this tedious configuration? In this backward and self-sufficient DIY age, the answer is no doubt certain for the tillers in the male and female workshops!Sggw module DIY Solution Openvpn and other IP-layer VPN

broadcast network, it needs to resolve the layer-3 address to the link layer, so ARP is inevitable, all the tap-mode NICs that are connected by user-assisted processes such as openvpn belong to an Ethernet LAN, regardless of the physical distance between them. ARP is used for address resolution, in addition, the tap-mode virtual network card can encapsulate layer-3 data of non-IP protocol. In essence, it fully simulates 802.3 Ethernet. The NIC initia

ConceptThis will not be said. The tap of OpenVPN and the VTI of Cisco IPSec VPN, including the NVI described below, all belong to virtual interfaces, and all virtual interfaces can import data packets through routing, as for what operations are performed in the interface, this is where the Virtual Interface is "virtual". You can export data packets to character devices, encrypt and decrypt data packets, or perform NAT...1. Linux 2.4 nat routeIn Linux

automatically encapsulate the source IP address for me. For example, it is obvious that you are using OpenVPN. First, let's take a look at the essential meaning of the so-called default gateway. The default gateway is actually a special "Next Hop", which is actually a next hop address. The purpose of this address is to throw data packets to the next hop (nonsense ), in fact, it is only an auxiliary function. What actually works is the MAC address res
