在softether 的server.c中找到
// The SoftEther VPN Project intentionally disables these functions for users
// in Japan and China. The reason is: Daiyuu Nobori, the chief author of
// SoftEther VPN, has been liable to observe the existing agreements and
// restrictions between him and some companies. The agreements have regulated
// the region-limited restriction to implement and distribute the above
// enterprise functions on the SoftEther VPN open-source program.
//
// Therefore, the SoftEther VPN Project distributes the binary program and
// the source code with the "SiIsEnterpriseFunctionsRestrictedOnOpenSource"
// function. This function identifies whether the SoftEther VPN Server
// program is running in either Japan or China. If the restricted region is
// detected, then the above enterprise functions will be disabled.
//
// Please note that the above restriction has been imposed only on the
// original binaries and source codes from the SoftEther VPN Project.
// Anyone, except Daiyuu Nobori, who understands and writes the C language
// program can remove this restriction at his own risk.
//
bool SiIsEnterpriseFunctionsRestrictedOnOpenSource(CEDAR *c)
{
char region[128];
bool ret = false;
// Validate arguments
if (c == NULL)
{
return false;
}
SiGetCurrentRegion(c, region, sizeof(region));
if (StrCmpi(region, "JP") == 0 || StrCmpi(region, "CN") == 0)
{
ret = true;
}
return ret;
}
直接改为return false就行了

最近在寻找比较好用的开源VPN，感觉SoftEther很符合我的需求。一方面是SoftEther属于开源软件并且一直在更新，另一方面是功能强大，好用。
VPN支持路由功能和NAT功能，还支持多种类型的VPN接入，看图。目前我的需求是NAT并做用户分组，对用户做访问控制。
我的服务端部署环境是WIN2012R2_X64，可直接在官网下载服务端和客户端：https://www.softether.org/5-download
在服务端配置过程中遇到一个问题就是不能下发明细路由，这里叫他拆分隧道。如果不处理这个问题，所有请求都会从VPN饶。
但是在SoftEther VPN下发明细路由推送的时候提示：不支持此功能。它尚未在SoftEther VPN的开源版本上实施。
刚开始以为是有付费授权，后来发现不是这个原因。
在找到相关函数，所以只要保证不要满足中文环境就可以突破
修改方式：
安装好服务端以后，修改vpnsmgr_x64和vpnserver_x64函数返回值就可以，OD载入搜索CN，JP关键字，看到或条件的比较满足条件就会触发
mov dword ptr ss:[rsp+B0],1
将1的写入，改成0的写入
测试可行
