SSH through gateway to implement port forwarding
Compared with the previous on two virtual machines via SSH port forwarding to achieve secure communication, this experiment in two virtual machines to join the gateway.
First, the experimental environment:
Three Linux virtual machines, VM1 (172.16.1.2) belong to the Vmnet1 subnet, vm2 (172.16.2.2) belong to the Vmnet2 subnet, gate as a

In Gartner's information security Report of August this year, NGFWS, in principle, does go beyond the state port and protocol filtering mechanism of the common firewall, which can perform part of the intrusion prevention function based on deep packet detection technology, and on some high-end devices, can also provide port/ The identity attribute management and policy execution function of a protocol-independent application.
The report also highlights, however, that while many companies claim t
Generally, all hosts in the same CIDR block have the same default route with the gateway as the next hop. When the gateway fails, all hosts that use the gateway as the default route in this segment cannot communicate with the external network.

Introduction
1. About the SIP protocol
Currently, there are three basic communication protocols based on VOIP: H 323, SIP, and MGCP. The following describes the comparison between the H 323 protocol and the SIP protocol.
H.323 was proposed by ITU. It attempts to regard IP phones as well-known traditional phones, but the transmission mode is changed from circuit switching to group switching, just like analog transmission to digital transmission, and coaxial cable transmission to optical fiber tra

The security technology of IPv6. Although IPv4 network security is a common problem, it is also a problem to be asked. Now let's talk about the IPv6 Security Gateway information. Now let's take a look at the specific content.

So what exactly is a gateway? A gateway is essentially an IP address of a network to another network. For example, network A and network B, network A's IP address range is "192.168.1.1~192." 168.1.254 ", the subnet mask is 255.255.255.0; The IP address range for 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 router, TCP/IP communication between the two net
Centos6.5 Implementation of Gateway Router
Recently, due to the aging of the company's routers, the Internet was interrupted for a period of time, and the network was disconnected for the first half of the hour. This is a headache for me. In the spirit of saving costs for the company, I decided to build a centos gateway route by myself, so I searched for it on the Internet and finally completed the
