The previous article wrote about the use of Haproxy's own lb and certificates, which is mainly about safety and reliability.Multi-tiered load balancing meets security and business needsEnterprise Security and Firewall policy is a disaster for PCF, of course, the current version has availability zone to cover this demand, but the following requirements are still difficult to achieve: PCF deployed in the production network, but need to be Internet access, The security policy only allows the

. firewalld has a graphical interface and a tool interface. for details about the graphic interface, refer to the official documentation, this document introduces the character interface management tool of firewalld as follows: Firewall-cmdFirewalld has two default configuration files:/usr/lib/firewalld/(system configuration, do not modify as much as possible) and/etc/firewalld/(user configuration address) zone concept: by default, a hardware firewall generally has three zones. when firewalld in

In the Tp-link Router Settings page forwarding rules to select the DMZ host, the DMZ state setting enabled, the DMZ host IP address to fill you from the router DHCP server to obtain IP, if your router compared to more people on the Internet may each t

sure the router is secure. Ensure that other devices are not accessible Compared to routers, it is easier to make sure that printers, cameras, and other devices are not accessible over the Internet. Assuming that these devices are connected to the router, it is entirely possible to control whether they can be accessed from the router. These devices should be isolated from the Internet and can only be safely accessed from the local network. The port forwarding and

Firewall English name is firewall, refers to the computer and its connected network between the hardware or software, can also be located between two or more networks, such as the LAN and the Internet, all the data flow between the network through the firewall (see figure). Firewalls allow you to scan communications between networks, turn off unsafe ports, prevent external Dos attacks, and block Trojan horses, to secure your network and your computer. Firewall is roughly divided into hardware f

the other end. This enables the load balancing on several firewalls, so that the firewall can run in parallel, extending the performance of the firewall and eliminating the possibility of a firewall becoming a single point of failure. Unlike traditional packet switches, web switches have the ability to maintain different TCP sessions that are transmitted over Ethernet and Gigabit Ethernet rates. Because the firewall is a stateful (stateful) device, all packets associated with the establishment

application environment. The maximum value I tested is "1 + 1 equals 1.8. In particular, if there is only one broadband or multiple sub-accounts using "My ehouse", dialing will not achieve the effect of bandwidth superposition. In addition, the effect of multi-task download bandwidth overlay is more obvious. TIPS: Which routers can enjoy the new firmware version of the tomato DualWan router? Vrouters such as TP-link, tengda, and Alpha cannot use Tomato DualWan. For more information about the su

With the development of China's routing industry, Cisco Wireless routers are also widely used. Here we mainly introduce a beautiful Cisco Wireless Router WRT54G2, last year, Cisco Consumer Division launched a newly designed 54M wireless route Linksys by Cisco WRT54G2. The elegant and slim design conforms to the current fashion trends of home entertainment and SOHO offices. Currently, this product is priced at 350 yuan in the market. It is very suitabl

This article describes how to set up a wireless LAN for a home. You can search a lot of articles on the Internet. These articles seem very good, not only the detailed process description, but also related images. The lessons learned are shared with you. The wireless router uses NETGEAR WGR614 (54M is 802.11g), and the NIC is also 54M (the configuration is very smooth, so I did not carefully look at the specific model). The reason why NETGEAR is used is, "NETGEAR is the best except Cisco-

protocol. In addition, the problems caused by WEP are also quite tricky, because the symptoms of problems caused by WEP mismatch are very similar to many serious problems. For example, if WEP is configured incorrectly, the wireless client will not be able to obtain the IP address from the DHCP server of the wireless network, even if the DHCP function is provided by the Wireless Access Point ). If the wireless client uses a static IP address, it cannot ping the IP address of the Wireless Access

be managed. If yes, test the forwarding performance for 5 minutes. The notebook is connected to a Wireless Broadband Router with a pair of two meters away and is in the same CIDR block as the 1600T simulated host. Function verification Use Cisco ESR 10000 to simulate the real environment, verify functions such as PPPoE, and evaluate the functions of the Wireless Broadband Router, such as UPnP, access control, priority division, traffic statistics, and diagnostic tools. Through tests, more than

DHCP information is frequently negotiated between the computer and the wireless router. In fact, these DHCP packets are completely unnecessary. For home users, there are not many computers in the network. We can completely reduce DHCP packets by manually setting network parameters such as IP addresses. A friend once told me that the wireless network in his house was unstable. Later, no DHCP was needed to directly specify an IP address and no longer dropped. (3) wireless network stability-speed

various potential problems. The vro setting Guide clearly tells you how much effort you have made before running the CD. Have you read the manual before you insert a new device? Almost all routers have a Web-based configuration interface. As long as you remember the IP address, default user name, and password of the device, you can go to the configuration screen and make any necessary adjustments. This is just a process to determine which adjustments are needed. Independent configuration softwa

1. Understand the firmwareThe most widely used flash firmware in China is the DD-WRT and TOMATO, both of which are the best in terms of functionality and stability. On the Internet, many third-party firmware files are released after the two firmware files are modified or updated. For example, DualWan firmware files are developed based on the TOMATO firmware files.Therefore, whether a wireless router can brush the firmware, the key to see whether it supports DD-WRT or TOMATO firmware.2. Which dev

Step 1 of wireless route connection settings: configure the network card to prevent others from sharing your wireless network. It's easy to complete the settings. Hurry into the Wireless World. Wireless route connection settings First, confirm that the wireless network card is installed. You can confirm it in the Device Manager ,. Set wireless network adapter for wireless route connection Then, check the vro settings, connect the vro to the vro using a network cable, and enter 192.168.1.

it more flexible in practical applications. Http://wireless.it168.com) In contrast, we often use wireless routers. In fact, each wireless router also has an operating system OS, and the operating systems of the wireless routers of each manufacturer are different, and no code is published, this is similar to the Windows operating system. Although we can use these wireless devices normally, the OS cannot be modified by ourselves, therefore, it is inevitable that one or more deficiencies exist in

At the request of the dynaguy brothers, I have attached a relatively complete experiment to colleagues who are still exploring: (There are some problems with the 2.0beta experiment, so I will demonstrate it with the most stable 1.2.3) In this test, we did not discuss the issue of using the SIP Trunk directly to connect other sip servers without board installation to enable the SIP users to make external calls. This article is only used to discuss questions about using the fxo card to test intern
