checkpoint hardware firewall

[Document Introduction]If we take a closer look at some hardware NAT routing firewalls that require hundreds or even thousands of disks, we may find that, the CPU clock speed and memory capacity of these devices may be inferior to that of a 486 computer, Some time ago, many small LAN users were unable to share the Internet due to a special attack against the virus with a cat routing. In this way, the devices that we bought together would be useless. T

All along, hardware professional firewall products are in the eyes of the user to create a mysterious and unattainable impression, firewall cheap price and product function is powerful like fish and Bear's paw, both often can not have both, its at a price of hundreds of thousands of yuan is not generally commercial users can afford. The number of hidden dangers a

Some time ago, many small LAN users were unable to share the Internet due to a special attack against the virus with a cat routing. In this way, the devices that we bought together would be useless. To address this problem, there are also related solutions on the Internet. In general, there are two solutions: 1. Buy a router with a firewall, but working-class people like us don't want to spend a few hundred dollars to buy another device. 2. Use a comp

Today, the main character is the chassis. Many hardware firewalls are just PCs with multiple NICs. They only use UNIX operating systems and have customized a special chassis-a box, which is worth hundreds of times. The magic box that makes PC accessories worth hundreds of times is a 1U steel shell firewall chassis. Today, I chose a Firewall Router professional 1

If DDoS attackers increase attack traffic and consume the total outbound bandwidth of the data center, any firewall is equivalent to a firewall. No matter how powerful the firewall is, the outgoing bandwidth has been exhausted, and the entire IDC seems to be in a disconnected state, just like a door already crowded with people, no matter how many guards you have

A remote backup was scheduled this morning, but I found that the entire backup process was not completed successfully.The exception is thrown repeatedly during the backup process:Java.net.SocketException:Connection ResetStrangely, in the previous one months, each backup can be completed successfully, but today is always throwing such a mistake.I started thinking it was a problem with the program, but I checked for more than 10 minutes and didn't find the cause.Later I began to wonder if the serv

Part I see: How to configure a hardware firewall 10. Address Translation (NAT) The NAT configuration of a firewall is basically the same as the NAT configuration of a router, and it must first define the internal IP address group for NAT conversion, and then define the internal network segment. The command that defines the internal address group for NAT conver

The port itself is turned on by default, but does not mean that the link to the port must be up. Only link devices are connected and connected devices such as PC are working properly ...Three-layer switch port, still have 24, or fa0/1-24, its three-tier routing function is not implemented through the FastEthernet port, but through its VLAN interface to achieve,therefore, on the two two-layer switch of unicom, it is necessary to configure VLAN to realize interoperability. Accordingly, the export
