windows中手工调整活动路由表的简单方法

前言

我司有个小程序，用UDP通讯读写设备参数，用来改IP这些出厂参数。
在我所有同事和现场计算机上运行都好使。唯独在我开发本上不好使。
我运维同事让我重装win10, 这哪能听他的…, 这么暴力的主意.

这事是一定要解决的，问题在哪呢？

那个程序有源码, VB6的，写的早了。
前段时间，装了个VB6, 将广播地址改了，当时可以在我开发本上能搜索到设备并改参数。就以为以前同事写的广播地址不大对呗。

前天，给我新做的4G短信猫写插件。
这套软件中，需要连一个我们的带IP的设备，需要先改设备IP.
用原版的UDP程序搜不到设备。
用我改过广播地址的UDP程序也搜不到设备。

用wireshark抓包，发现只有本本用的WLAN网卡上有UDP发包。
USB转网卡那个网卡(设备接在这块临时网卡上)没有收到UDP广播包。

当时的想法：以前同事咋不指定网卡发广播包啊？那自己动手写一个简版的实现吧。

用了1天写完界面和基础代码。今天开始写指定网卡发广播包。
突然发现，windows下的socket不支持发包时指定网卡（setsockopt 选项中就没有 SO_BINDTODEVICE），只有linux才行。。。

那咋弄？
看看能不能调整路由表顺序，将接设备的那块网卡顶到活动路由表的顶部。
试试好使，记录一下。

以前同事跟我说过，将无线网卡禁用，再试试UDP程序好使不？
我现在才明白，他们不是研发，计算机上装的软件少，计算机上可能就只有内置物理网卡和USB转网卡2块网卡。

而我计算机上网卡在系统中的网卡列表处（控制面板\网络和 Internet\网络连接）有5块。

经过试验，不用禁掉其他网卡，只留USB转网卡，那样上网啥的就不行了。
正确姿势是：

将全部网卡都禁掉。
再按照自己想使用的网卡优先级，一个一个启动。那样在活动路由表中，先开启的网卡，就在活动路由表最上面，包优先发向那块网卡。

试验

我接设备的网卡是网卡转USB转出来的。IP是 192.168.2.x
主网卡是内置wifi接我家里的路由器。IP是 192.168.1.x进入系统中的网卡列表处（控制面板\网络和 Internet\网络连接）
将能看到的网卡都禁用了。查看路由表中的活动路由（网卡全禁用）C:\Users\chenx>route print

===========================================================================可以看到 WLAN网卡在活动路由中，也排在USB转网卡后面。这时再运行UDP程序，可以看到有回包了。
用wireshark抓包也能证明这点（在USB转网卡那块网卡上，能看到UDP程序发出的指定UDP包和设备回包）。试验结论：
如果是做临时试验，想让哪块网卡的活动路由优先，只需要先启动那块网卡即可。
不过这么做，将临时网卡顶到最上面，能明显感觉到网页访问最开始会慢很多，应该和主网卡不在活动路由表最上面有关系。等做完试验，将主网卡顶到活动路由表最上面好些。要不访问网页时，等的有点心慌。

试验结束

为了这个试验，开始想写的UDP简版程序已经写到一半了，对于这个试验来说没大用了。已经弄清为啥UDP程序在我计算机上不好使。

可是自己点的菜，即使吃撑了，也要强忍着眼泪继续吃完。
如果不是自己点的菜，真不想继续弄。

写UDP简版程序去了:)

UDP简版程序

将测试程序写完了，以后能用上，贴在这。
程序里面加上了搜索网卡的功能，因为windows无法指定网卡发包，实现先留着。
编程环境：vs2017 + MFC dlg
中间遇到的问题：

sendto, recvfrom后会有错误码，是socket建立，sendto, recvfrom函数参数写的不规矩引起的。找msdn和大家写好的UDP代码对一对，能看出区别。
