Assume that the domain name blog.s135.com is resolved to the public/public network virtual IP address of F5: 61.1.1.3 (vs_squid). The virtual IP Address has a server pool (pool_squid ), the server pool contains two real squid servers (192.168.1.11 and 192.168.1.12 ).② If the Squid cache does not hit, it will request the

The server pool consists of two real squid servers (192.168.1.11 and 192.168.1.12).②, if the squid cache misses, the F5 intranet virtual ip:192.168.1.3 (Vs_apache) is requested, and there is a default server pool (Pool_apac

Enter in the URL address bar: Such a refresh, you can see in the Firebug, only a few requests will be sent out, and almost no picture of the request, this is because the request will first check whether the local cache of the requested picture, If there is a cache and there is no expiration (the expiration can be viewed through the header of the picture request), he will not issue the picture requests.F5:f5 refresh is slightly slower than enter, for w

F5 session persistence, f5 session In recent projects, F5 needs to be used for load balancing and relevant information should be recorded. The following is a description of the relevant parameters in the F5 change application. Let's take a look at them. Let's pick several important parameters to learn.

Iptables implements network firewalls: SNAT, DNAT, and iptablessnatIptables network firewall (2)-Introduction to SNAT and DNAT ?? In the previous article, we briefly introduced the basic concepts of the firewall in the LINUX kernel, as well as the four-table-five-chain knowledge. For more information, see Introduction to the LINUX firewall. It also introduces how to set up a simple network firewall that can

like you find a box of milk that has expired, so ask others, can not drink, if others say yes, you drink it, if others say no, then you have to find another box of fresh milk.As for F5 Refresh, its HTTP request message header is as follows:Host 192.168.3.174:8080User-agent mozilla/5.0 (Windows NT 5.1; rv:5.0) gecko/20100101 firefox/5.0Accept text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8Accept-language zh-cn,zh;q=0.5Accept-encoding g

Original article address: differences between SNAT, DNAT and masquerade in iptables Author: zhengsenlin888 Differences between SNAT, DNAT and masquerade in iptables Solution In iptables, You can flexibly perform various network address translation (NAT) There are two main types of Network Address Translation: SNAT and DNAT.

NAT is the abbreviated network address translation of the translation There are two main types of network address translation: Snat and Dnat, that is, source address translation and destination address translation SNAT: Source Address Translation Eg: multiple PCs using ADSL routers to share the Internet Each PC is configured with the intranet IP, when the PC confidential access to the external network, the

, the system returns 304 not modified. After the browser receives the modification, it reads the content from the cache. If it is modified, the system returns 200.OK, and new content is returned. In this situation, you find a box of expired milk, and ask someone else if they can drink it. If someone else says yes, you will drink it. If someone else says no, then you haveFind a box of fresh milk. For F5 refresh, the HTTP request message header is as

Through previous learning (SEE), we learned about the table and link structure of the linux Firewall and learned to write simple firewall rules, next we will add the SNAT source address translation and DNAT target address translation policies of the linux firewall. familiarity with their usage and usage is the basis for us to master the firewall. Next we will start learning: Recommended reading: Iptables-packet filtering (Network Layer) Firewall Linux

Differences between SNAT and masquerade in iptablesIn iptables, You can flexibly perform various network address translation (NAT)There are two main types of Network Address Translation: SNAT and DNAT.SNAT is the abbreviation of source network address translation, that is, source address target conversion.For example, multiple PCs use the ADSL Router to share the Internet. Each pc is configured with an intr

access public network hosts in the LAN. Therefore, by applying the Snat policy in the gateway, we can solve the problem of LAN sharing Internet.Analysis of the principle of snat conversionSnat the application of the strategy, or based on the experimental environment, set up the Snat firewall rules, before setting up Snat
