Article title: modify the gateway in Linux. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source. Take the root user as an example and execute the following command: # Route add default gw xxx. xxx (IP address of the Gateway) To change the
Today, we will learn about Internet protocols in terms of addressing, segmentation, and gateway. The addressing method is also the address method we currently use in the IPv4 protocol. With the continuous development of the network, we will replace the current IPv4 with the IPv6 protocol, and the address protocols of the two are also different. In the subsequent articles, we will also compare the two. Addressing There is a difference between the name,
So what is the gateway? A gateway is essentially a network that leads to its IP address. For example, if Network A and Network B exist, the IP address range of Network A is "192.168.1.1 ~ 192. 168.1.254 ", The subnet mask is 255.255.255.0, And the IP address range of Network B is" 192.168.2.1 ~ 192.168.2.254 ", and the subnet mask is 255.255.255.0. In the absence of a vro, the two networks cannot communicat
Under normal conditions, two NICs of a server can only be configured with one gateway. If both NICs are configured with a gateway, I am sorry. At this time, the network will fail, there must be at least one NIC address. The last time I went to the hosting data center to install the server for the customer, one Nic needs to be configured with a public IP address, the gat
C # communication gateway development, The landlord has been engaged in the development of communication gateway most of the time since he graduated from 12 years. He just learned that he would not even know what C # is, so he started to develop the gateway directly, five or six communication protocols have been established before and after. Later, I saw that th

Creating a Secure RD Gateway is a great thing, so you can access the internal remote access host server directly from the public network environment. The material needed to build this secure RD Gateway is the RD gateway itself, as well as a certificate. Because typically these servers behind the RD Gateway are resourc
