//说明介绍//
Sniffer抓包命令使用：
diagnose sniffer packet any "host 192.168.200.102 and icmp" 4
关于sniffer抓包需注意：如果数据已经被NP加速了，则可能sniffer抓不出来，为了准确的抓到数据，可能需要注意调整一下NP加速和已经建立好的Session： sniffer注意1：在相关的VPN业务流量的策略下临时关闭NP加速（抓包完毕再打开NP加速）： FGT # config firewall policy FGT (policy) # edit 1 （假设业务相关策略的策略ID为1） FGT (1) # set auto-asic-offload disable FGT (1) # end 这样所有与策略相关的数据处理会全部走CPU，因此sniffer才可以完整的抓到数据流。 sniffer注意2：对于已经建立起来的会话（数据已经走了NP处理），即便关闭了 NP，也抓不到包，因此需先将此session过滤出来然后再清除掉这条session，让其再新建就抓到包了： FGT#diagnose sys session filter dst 192.168.200.102 （过滤 目的IP） FGT#diagnose sys session filter proto 1 （过滤协议 1：ICMP 其中包括了ping） FGT#diagnose sys session clear （清除过滤后的Session） FGT# diagnose sys session filter clear //清除session过滤条件 FGT#diagnose sys session filter dst 192.168.200.102 （过滤 目的IP） FGT#diagnose sys session filter proto 6 （过滤协议 6: TCP） FGT#diagnose sys session filter dport 443 （过滤 TCP Port 443端口） FGT#diagnose sys session clear （清除过滤后的Session） FGT#diagnose sys session filter src 192.168.200.102 （过滤 源IP） FGT#diagnose sys session filter proto 6 （过滤协议 6: TCP） FGT#diagnose sys session filter dport 443 （过滤 TCP Port 443端口） FGT#diagnose sys session clear （清除过滤后的Session） FGT# diagnose sys session filter clear //清除session过滤条件 FGT#diagnose sys session filter dst 192.168.200.102 （过滤 目的IP） FGT#diagnose sys session filter proto 17 （过滤协议 17: UDP） FGT#diagnose sys session filter dport 500 （过滤 UDP Port 500端口） FGT#diagnose sys session clear （清除过滤后的Session） FGT# diagnose sys session filter clear //清除session过滤条件 最后开启抓包，FortiGate抓包命令如下： FGT#diagnose sniffer packet any "host 192.168.200.102 and icmp" 4 FGT#diagnose sniffer packet any "host 218.203.193.18 and esp” 4 FGT#diagnose sniffer packet any "port 500 or port 4500 and host 1.1.1.1" 4 FGT#diagnose sniffer packet any "host 10.101.2.2 or host 111.204.123.112 and port 22" 4 FGT#diagnose sniffer packet any "host 60.31.254.5 and port 53" 4 FGT#diagnose sniffer packet any "host 192.168.118.57 and icmp" 4 FGT#diagnose sniffer packet any "port 9999" 4 ----------------------------
Debug Flow的使用：
Debug Flow 通常用于定位调试穿过或访问FortiGate数据流的处理过程，如果不通，可以使用debug flow协助定位，非常好用的数据流分析工具。
Debug flow的命令解析： #diagnose debug flow filter addr x.x.x.x //过滤某个IP #diagnose debug flow show console enable //在串口上显示trace内容 #diagnose debug flow show function-name enable //显示功能模块名称 #diagnose debug flow trace start 999 //开启debug flow trace并显示999条debug信息 #diagnose debug enable //开启debug命令 #diagnose debug flow trace stop //关闭debug flow trace #diagnose debug flow filter clear //清除过滤条件 #diagnose debug disable //关闭debug命令 #diagnose debug reset //重置所有的debug命令 最关键的Debug flow的过滤条件，举例： 1.过滤ping流量 #diagnose debug flow filter proto 1 改变相应的proto就可以过滤相应的协议流量 proto 1 为ICMP协议 proto 6 为TCP协议 proto 17 为UDP协议 2.过滤某个IP的ping流量 #diagnose debug flow filter addr 192.168.1.100 #diagnose debug flow filter proto 1 过滤192.168.1.100的ping流量 3.过滤某个端口号 #diagnose debug flow filter port 8080 过滤port为8080的流量 4.过滤某个IP的Port8080流量 #diagnose debug flow filter addr 192.168.1.100 #diagnose debug flow filter port 8080 过滤192.168.1.100的port8080的流量 5.过滤源端口/目的端口 #diagnose debug flow filter sport 80 ----->过滤源端口80 // #diagnose debug flow filter dport 25 ----->过滤目的端口25 6.过滤源IP/目的IP #diagnose debug flow filter saddr x.x.x.x -----> 过滤源IP x.x.x.x // #diagnose debug flow filter daddr y.y.y.y ----->过滤目的IP y.y.y.y 常用debug flow举例1：抓取10.10.10.100且ICMP的流量 diagnose debug flow filter addr 101.231.244.193 diagnose debug flow filter proto 1 diagnose debug flow show console enable diagnose debug flow show function-name enable diagnose debug flow trace start 10 diagnose debug enable 常用debug flow举例2：抓取10.10.10.100且TCP端口为10443的流量 diagnose debug flow filter addr 10.10.10.100 diagnose debug flow filter proto 6 diagnose debug flow filter port 10443 diagnose debug flow show console enable diagnose debug flow show function-name enable diagnose debug flow trace start 10 diagnose debug enable 常用debug flow举例3：抓取10.10.10.100且UDP端口为500的流量 diagnose debug flow filter addr 10.10.10.100 diagnose debug flow filter proto 17 diagnose debug flow filter port 500 diagnose debug flow show console enable diagnose debug flow show function-name enable diagnose debug flow trace start 10 diagnose debug enable 常用的debug flow复制粘贴脚本： diagnose sys session filter dst 10.3.10.1 diagnose sys session filter proto 1 diagnose sys session clear diagnose debug flow filter addr 10.3.10.1 diagnose debug flow filter proto 1 diagnose debug flow show console enable diagnose debug flow show function-name enable diagnose debug flow trace start 10 diagnose debug enable diagnose sys session filter dst 10.255.16.114 diagnose sys session clear diagnose debug flow filter addr 10.255.16.114 diagnose debug flow filter proto 6 diagnose debug flow filter port 443 diagnose debug flow show console enable diagnose debug flow show function-name enable diagnose debug flow trace start 100 diagnose debug enable // diagnose debug flow filter port 53 diagnose debug flow filter proto 17 diagnose debug flow filter port 80 // diagnose debug flow filter addr 103.17.88.71 diagnose debug flow filter proto 6 diagnose debug flow filter port 57720 diagnose debug flow show console enable diagnose debug flow show function-name enable diagnose debug flow trace start 10 diagnose debug enable diagnose sys session filter src 172.40.1.252 diagnose sys session clear diagnose debug flow filter addr 124.89.90.125 diagnose debug flow filter proto 17 diagnose debug flow show console enable diagnose debug flow show function-name enable diagnose debug flow trace start 10 diagnose debug enable diagnose sys session filter dst 116.90.243.115 diagnose sys session clear diagnose debug flow filter addr 222.92.132.166 diagnose debug flow filter proto 6 diagnose debug flow filter port 3134 diagnose debug flow show console enable diagnose debug flow show function-name enable diagnose debug flow trace start 6 diagnose debug enable diagnose debug flow filter addr 192.168.1.1 diagnose debug flow filter proto 17 diagnose debug flow show console enable diagnose debug flow show function-name enable diagnose debug flow trace start 6 diagnose debug enable diagnose sys session filter src 172.40.1.252 diagnose sys session clear diagnose sys session filter policy 5 diagnose sys session list diagnose debug flow filter addr 58.18.31.148 diagnose debug flow filter proto 17 diagnose debug flow filter port 161 diagnose debug flow show console enable diagnose debug flow show function-name enable diagnose debug flow trace start 10 diagnose debug enable ------------------------

IPsec VPN隧道起不来的问题定位：
首先，sniffer抓包确认UDP 500/4500 双方通信是否正常
diagnose sniffer packet any "host 116.6.100.241 and ( port 500 or port 4500)" 4
diagnose sniffer packet any "host 202.106.1.35 and ( port 500 or port 4500)" 4
//IP换成对方公网IP
UDP 500 或 UDP 4500 这两个端口是IPsec VPN协商协议IKE会使用的端口，一定要互通要通畅，否则VPN无法正常建立，确认互通正常在进行下一步定位
然后，通过日志，debug app ike 确认问题是出在第一阶段还是第二阶段
diagnose vpn ike log-filter name ipsec_wuxian1 // 第一阶段名称
diagnose vpn ike log-filter dst-addr4 124.65.148.86 //IP换成对方公网IP
diagnose debug application ike -1
diagnose debug enable
注意事项：debug app ike的时候要注意，自己不要主动发起连接，需要把第一阶段/第二阶段的自动协商关闭
注意一：可能需要关掉一阶段第二阶段的自动协商
如果是5.6之后的版本，只需要一条命令就可以完全关闭自己的主动发起的IKE连接请求：
config vpn ipsec phase1-interface
edit VPN-P1（第一阶段名称）
set passive-mode enable //永远不主动发起IKE请求，即便使用流量触发，也不主动发起
next
end
如果是旧版本(5.2/5.4)则需要分别关闭第一阶段和第二阶段的自动协商：
BJLab-240D # config vpn ipsec phase1-interface
BJLab-240D (phase1-interface) # edit VPN-P1（第一阶段名称）
BJLab-240D (VPN) # set auto-negotiate disable
BJLab-240D (VPN) # end
BJLab-240D # config vpn ipsec phase2-interface
BJLab-240D (phase1-interface) # edit VPN-P2 （第二阶段名称）
BJLab-240D (VPN) # set auto-negotiate disable
BJLab-240D (VPN) # end
注意二：有时候需要重置IPsec VPN的连接（请谨慎使用，所有的VPN都会重新连接IKE，一般不需要使用这个命令）
diagnose vpn ike restart //重新主动发起连接
diagnose vpn tunnel reset //重置第二阶段
diagnose vpn ike restart
diagnose vpn ike gateway clear
重置IPsec VPN通道，有VDOM的情况下：
FG200D4615810562 # config vdom
FG200D4615810562 (vdom) # edit root
FG200D4615810562 (root) # diagnose vpn tunnel reset

B1026 : possible packet out-of-order with NP6 during TCP session establishment - (new CLI)
[ History ]
- Issue was first reported by Bouygues Telecom with a FortiGate-3950B (NP4)
- Further testing was made with a FortiGate-1500D (NP6) where the problem can still be reproduced in the lab (FortiOS 5.4 GA)
- As suggested, opening a bug to track the issue.
[ Problem Description ]
When the host interface is busy (packets queuing in the FIFO), it is possible that the 3rd tcp session establishment ack received from the client is transmitted to the server
after data packets. This may or may not cause an issue to the server depending on the cases :
1) one single DATA segment managed to sneak before the 3rd handshake ACK :
Since the segment relative sequence number is 1 (just like the 3rd ack packet), it may be seen by the server as a TCP handshake 3rd ack containing data (piggyback).
When the real 3rd ack then arrives, it is considered as a duplicate ack but does not cause real problem to the application.
Note : If a stateful firewall exists between the FortiGate and the server, this may be a problem and generate a Reset causing the failure of the TCP session.
2) more than 1 DATA segments manage to sneak before the 3rd handshake ACK :
If 2 data packets sneak, the sequence number for the second packet is higher than 1 (depending on data length from the the first packet). In this scenario, the server may not consider the
tcp session handshake to be completed and sends a reset causing the session to fail.
These 2 scenario were observed and reproduced in the lab using traffic stressers.
It is not systematic to all sessions and require a busy host.
Reason for TCP handshake ACK out-of-order :
The reason for these scenario is explained in attached document "NP6_OOO_on_busy_CPU_v2.pdf"
Please note this document is for internal use only.
[ Diagram ]
See Diagram.png
[ Reproduction Scenario ]
This is reproduction from the lab run by Vincent.
Use an FortiGate-1500D running 5.4 GA with 4 ports where :
- 2 ports Port39 and Port36 are used to generate http 21k traffic (11K session per seconds, 2Gbps) passing through a UTM/IPS policy from an avalanche
=> The only goal of this traffic is to create a busy host interface condition.
- 2 ports Port33 and Port38 with a firewall only policy connected to avalanche generating SIP traffic.
=> SIP is chosen here because it allows to have the client sending more than 1 DATA packets immediately after the client has sent its 3rd ACK handshake packet.
A Breaking Point is used as a 'network probe' receiving traffic on the FortiGate server side from the switch configured with SPAN port.
Attached pcap files 'client.pcap' and 'server.pcap' are extracted from the breaking point in lab testing.

- client.pcap : pcap extracted from the switch port mirror, client side
- server.pcap : pcap extracted from the switch port mirror, server side
[ Expected Behavior ]
Fortigate should not create out-of-order packet during the TCP handshake.
