UDP会话中客户端和服务端识别错误
|
|||
|
|
|
|||
|
|
1、在提取QuarkVPN特征时候发现，VPN使用UDP协议的时候，服务器常用口端口为59001/59002/60000，数值比客户端随机分配的端口大
|
|||
|
|
|
|||
|
|
2、测试系统：工程部测试环境
|
|||
|
|
|
|||
|
|
CM：192.168.44.228
|
|||
|
|
|
|||
|
|
OLAP：192.168.44.229
|
|||
|
|
|
|||
|
|
TSG-OS：192.168.40.84
|
|||
|
|
|
|||
|
|
客户端IP地址：192.168.54.220
|
|||
|
|
|
|||
|
|
3、三个session均为连接VPN节点后，下载了一个2MB左右的文件，然后断开连接，保存的数据包
|
|||
|
|
|
|||
|
|
4、Session_Record、数据包见附件
|
|||
