Nat's Internet mode1. The host's virtual network card is not set (default is auto-acquired)2. The network card in the virtual system is not set (default is auto-acquired)The premise of this two implementation is that the virtual DHCP server works for everyone Figure 2Looking at a NAT Figure 3After looking at this 3 figure, we basically understand. But this is not convincing, let me explain here.Where 192.168.2.2 quite with the position of R teacher, in Figure 1 is marked with a virtual NAT serv

Ping tests are normal and test to see if the local cloud server's Web port is properly accessed. Telnet to the server IP 80web port and 3306 database port to see if the Web server Apache/nginx/iis or the database is functioning properly; If the local to the Cloud server Web port access is normal, and then through the

successful connections from home, small office network, or the Internet. When you select the log on successful outbound connection check box, each connection information that succeeds through the firewall is collected. For example, when anyone on the network uses Internet Explorer to successfully connect to a Web site, a project is generated in the log. Log discarded packets-this will log on to all discarded packets originating from the home, the small office network, or the Internet.

15 different values to describe a specific type of ICMP message. Some ICMP messages also use the values of the Code fields to further describe the different conditions. The checksum field covers the entire ICMP packet, and the algorithm is the same as the IP header checksum.inspection and: used to test the entire ICMP packet. However, the IP header checks and does not verify the contents of the IP datagram, so there is no guarantee that the transmitted ICMP message will not cause errors. ICMP m

Ipx/spx Two network protocols are proposed by NetWare company primarily for LAN and network games where the IPX protocol has the full name of the routing function Internetwork Packet Exchange (Internetwork Packet Exchange), the IPX protocol is the most low-level network protocol with Novell NetWare, which is mainly used to control the addressing and routing of packets between LAN or LAN, only responsible for the transmission of packets in the LAN, does not guarantee the integrity of the message

This plugin displays all such information in a pop-up Finally, don't forget to use tools like Firebug, YSlow, Ping, and tracert to detect whether a performance problem is from a network or a resource-loading p

the firewall makes an ARP reply, the switch encapsulates the MAC address of the firewall as the destination MAC address into the packet, the packet is sent to the firewall, and the firewall repeats the process, sending the data packages to the destination address on the Internet. All these processes are normal and there is no problem. It is also normal to use the TRACERT command to track routes in the ARP table of the computer and switch to find the

There are many command-line tools for the network, such as the familiar ping,tracert,ipconfig,telnet,ftp,tftp,netstat, and the unfamiliar Nbtstat,pathping,nslookup,finger, Route,netsh ... These commands can be divided into three categories: network detection (such as ping), network connectivity (such as Telnet), and network configuration (such as Netsh). The first two are relatively simple, and this article covers only two network configuration tools.

services on the other end of your T1 line, and the end result is effectively cutting access to your site. Consider a more complex environment where multiple routers are placed at both ends of a particular connection, and because each router is vulnerable to attack, it may affect the service of legitimate users of your site. To list the routers that the packets will pass to your server, use TRACERT. EXE utility. Configure TCP/IP filtering to limit the

packet, the packet is sent to the firewall, and then the firewall repeats the process, sending the data packages to the destination address on the Internet. All these processes are normal and there is no problem. In the computer and switch ARP table can find the corresponding ARP records, with the tracert command to track the route is also normal, the problem is where? It seems that we have to continue the analysis. Filter ARP Table Once the packet

How to turn off ICMP (Ping) in Win2000 The full name of ICMP is the Internet control and messaging protocal, the Internet-controlled message/error message protocol, which is used primarily for the transmission of error messages and control information. For example, the well-known ping and tracert tools are all made using the Echo request message in the ICMP Protocol (Request message ICMP echo type 8 code 0, reply packet icmp echoreply type 0 code 0).
