Firewalls and switches are still commonly used. So I studied how firewalls and switches implement Intranet/Internet isolation. Here I will share with you, hoping to help you. With the maturity and rapid development of network and Internet technologies, more and more enterprises and institutions have begun to set up networks to automate office work and share Internet information. However, security issues have also emerged. iMaxNetworks (memory network

as input. Note that the this documentation, referring to an IP address as an IPv4 address or an IPV6 address was a semantic property O f the address, not just the length of the byte slice:a 16-byte slice can still is an IPv4 address. Type IP []byte func IPv4 Func IPv4 (A, B, C, D byte) IP IPV4 returns the IP address (in 16-byte form) of the IPV4 address a.b.c.d. Donuts, see the documentation for more details: https://golang.org/pkg/net What is an

The problem is that there are two existing machines: intranet: one server on the intranet, which cannot be accessed directly from the Internet. Internet: the internet can access files and servers on the machine. At the same time, the machine can access any files on the intranet .. Due to historical reasons: the problem above the

threat outbreaks in the LAN. Relying on a single border firewall and anti-virus software, it cannot cope with viruses and other information security threats. Only by protecting each client can it effectively prevent virus intrusion, information leakage, and worms, network abuse and other problems. Therefore, Enterprise Intranet security management becomes increasingly important. Overview of Intranet Securi

as we all know, in order to infiltrate the intranet, you have to be in that intranet. But when you install Kali in VMware, most users do not choose bridging mode for convenience, but instead choose to use IP networks shared with nativeof course, this will be able to surf the Internet, but your virtual machine does not actually get the intranet IP. If you do not i

network, then basic NAT is responsible for translating the subnet IP of the node into a globally unique IP and sending it out. (Basic NAT changes the original IP address in the IP packet, but does not change the port in the IP packet). For basic NAT, refer to RFC 1631.Another kind of NAT is called NAPT, which we can see from the name.Napt not only changes the IP address of the IP datagram that passes through this NAT device, but also changes the TCP/UDP port of the IP datagram. Basic NAT Device

After writing object 672, a critical problem of the software is exposed. If both the server and client are in the Intranet environment, that is, both parties use NAT to access the Internet, in this case, the client cannot directly communicate with the server. The solution can be: 1: deploy the server in a public network without Nat. 2: Use common Nat penetration methods, such as UDP injection or STUN Protocol. However, these methods require another kn

In the TCP/IP protocol, three IP address zones are reserved for private addresses with the following address ranges:10.0.0.0/8:10.0.0.0~10.255.255.255172.16.0.0/12:172.16.0.0~172.31.255.255192.168.0.0/16:192.168.0.0~192.168.255.255So, go directly to the code:Public Static BooleanInternalip(String IP) {byte[]Addr= Ipaddressutil.textToNumericFormatV4(IP);returnInternalip(Addr);}Public Static BooleanInternalip(byte[] addr) {Final byteB0= addr[0];Final byteB1= addr[1]; //10.X.X.X/8 Final bytes

For the intranet computer is able to access through the router, because the router assigned an IP address, so that the computer has an identity, if the router can not be assigned to the computer IP situation, then we have no way to the Internet. First, the emergence of IP can not be assigned to the phenomenon is most of the client can not log in, can not get IP after login or very slow, in the operating system command prompt in the use of Network com

The specific analysis is as follows: In the TCP/IP protocol, three IP address areas are reserved for private addresses, and their addresses range as follows: 10.0.0.0/8:10.0.0.0~10.255.255.255172.16.0.0/12:172.16.0.0~172.31.255.255192.168.0.0/16:192.168.0.0~192.168.255.255 So, go directly to the c
