For the sake of security, machines with important content such as web servers, databases, and billing may be hidden behind the firewall, even without an Internet address. Here, we assume that we need to set a linux gateway for a web server with only an intranet address so that the Internet can access the web, but the access from other ports is blocked. Iptables is provided by the Linux kernel above. for security reasons, machines with important conten

　　To create a NAT gateway Describe Creates a NAT gateway in the specified VPC. Some notes: Nat Gateways and "Self-built Snat gateways" (using an ECS as Snat Gateway) are not currently supported in VPC, and if so, undefined product behavior is generated (this usage will be supported in future product iterations) When the Nat

In the advanced properties of the VPN connection, there is an option-"Use a default gateway on a remote network"-what is the benefit of shutting him down? We know that once the VPN server is connected, our local network data will go through the remote server, and the external IP address will become the IP address of the remote server. The domestic VPN is fine, if the United States. Then we will be very slow to visit the domestic network data, the rea

There are several machines in there that do not ping the gateway, but the other machines in the ping switch can ping, and other machines ping the gateway can ping. Then the hardware is discharged, and the main problem is on the routing table of the machine. Look at the routing table. Route-n Destination Gateway genmask Flags Metric Ref use
