FWPS_FIELD_ALE_FLOW_ESTABLISHED_V4_DIRECTION [英] FWPS_FIELD_ALE_FLOW_ESTABLISHED_V4_DIRECTION

问题描述

flowContext-> direction = 

          inFixedValues-> incomingValue [FWPS_FIELD_ALE_FLOW_ESTABLISHED_V4_DIRECTION] .value.uint16;

以上值始终为0，除非某些条件224.0.0.252的ip地址，有人能给我一些建议吗？谢谢。

解决方案

1）确保inFixedValues-> incomingValue [FWPS_FIELD_ALE_FLOW_ESTABLISHED_V4_DIRECTION] .value.type！= FWP_EMPTY

2）方向的0表示FWP_DIRECTION_OUTBOUND

希望这会有所帮助，

flowContext->direction = 
         inFixedValues->incomingValue[FWPS_FIELD_ALE_FLOW_ESTABLISHED_V4_DIRECTION].value.uint16;

the value above is always 0, unless some condition 224.0.0.252 ip address, can anyone give me some advices? thanks.

解决方案

1) make sure the inFixedValues->incomingValue[FWPS_FIELD_ALE_FLOW_ESTABLISHED_V4_DIRECTION].value.type != FWP_EMPTY

2) 0 for the direction means FWP_DIRECTION_OUTBOUND
