Network address port Conversion NAPT is a very familiar way of transformation. NAPT is commonly used in access devices, which can hide small and medium-sized networks behind a legitimate IP address.Unlike dynamic address NAT, NAPT maps An internal connection to a separate IP address in the external network, adding a TCP port number selected by the NAT device to the address.This time, let's get to know napt.Configuration ideas1 Configure the router's interface IP address, note the network segment

RIP protocols can be configured in a more convenient way, but the limitations of RIP itself indicate that it is not suitable for medium to large networks. In contrast, OSPF is more complex to configure than RIP, but its functionality and performance are better than RIP.Configuration ideas1 Configure the physical interface address of the router Xia Lian switch and the physical interface address of the router to the other router and open the port2 Configure the address of the switch Xia Lian PC an

Problem Description:Cisco Packet Tracer software configures switches in the CLI, routers enter information with IP type when entering "." The input character jumps to the first bit of the string or "."

Cisco router in the configuration of ports, or to understand the next few port names and purposes more meaningful, s port is the meaning of serial interface, also known as high-speed asynchronous serial port, is mainly connected to the WAN v.35 cable, commonly said routers and routers when used in connection. F port is a fastethernet interface, called Fast Ethernet port, mainly connected to Ethernet (LAN) used, the popular saying is to connect switches, computers, with the common twisted pair

UDP packet LengthThe theoretical length of UDP packetsWhat is the theoretical length of UDP packets and what should be the appropriate UDP packets? As can be seen from the packet header of the UDP packet in the 11th chapter of TCP-IP, the maximum packet length of UDP is 2^16-1 bytes. Since the UDP header accounts for 8
