我自己实验rst阻断,一个程序用来抓包 一个用来发rst 我连ftp 提示输入用户名后 抓报了几个包,取从本机发向服务器的最后一个包的信息(端口号,tcp序列号) 然后给rst包发送程序。字节序我改了,rst包也测试的确发出去了,可是为什么ftp就是没有阻断,仍然可以连接?
server端接收client端发过来的数据,client发送完后close socket, server端recv没有把数据全部接收完,而是出错,检查错误码后得知是收到了rst,这是为什么,怎么解决
Openswan IPSec is an open source implementation of IPSec that is included in many Linux distributions. When appropriately configured, it can interoperate with fortigate VPNs. Global settings The global settings for the Openswan IPSec service are found in /etc/ipsec.conf. Unless you are certain that you don't need NAT traversal, ensure that the following line appears in ipsec.conf: nat_travers...
Configure the fortigate unit Configure the Phase1 and Phase 2 VPN settings To configure the Phase1 settings Go to VPN > IPSec > Phase 1. Select Create New and enter the following: Gateway Name: SonicWall Remote Gateway: Static IP IP Address: ip address Mode: Main Authentication Method: Preshared Key Pre-shared Key: preshared key Select Advanced and enter the following: Encryption: 3DES Authentic...
Case Scenario You have to two groups of users attempting to access the Internet through the fortigate. Most users need to be restricted in their access to the Internet. A few select users are permitted unrestricted access to the Internet. General Question How can the fortigate distinguish between the two sets of users? The solution is to enforce firewall authentication against two distin...

小弟最近给同一内网的兄弟用BT下载搞的很是苦恼。因为是HUB,于是想一个点子。用winpcap截包,如果包的源IP是他的,则给目的IP发送rst标志的包。由于对TCP协议不是很了解,包包截取到后,修改了rst标志后直接再发送,但就没有任何效果,用自己机器测试,上网仍然很正常。 考虑到WINPCAP和LIBPCAP都差不多,就发在这里了,望见晾。代码如下: [code] // deny.cpp : Defines the entry point for the console application. // #incl...
fortigate配置使用policy route 环境 CN分支使用fortigate 200A作为防火墙,一条出口线路; VN分支使用fortigate 100A,两条出口线路; US分支使用linksys,一条出口线路。 现在要把三地分别用vpn连接起来,问题主要在VN的双WAN上 起先WAN1使用XDSL modem动态拨号,WAN2是静态ip,直接通过fortigate pppoe获得ip vpn走wan2,其他走wan1 1 VNCN CN ip:222.222.66.2(假设ip) 内网ip:192.168.0.0/20 1.1 首先需要在VPN-...
