MikroTik和Kerio Control之间的IPSec VPN连接

• 4.1在“预定义的密钥：”字段中，输入将用于连接的密钥；
• 注意事项：
  
  我绝对建议在一个特定的Kerio服务器上创建的所有VPN隧道中设置所有关键短语！
  
  这是由于Kerio具有一个浮动错误，如下所示。
  
  想象一下，在我的情况下，在Kerio配置中，有多个配置为连接到MikroTik的“ VPN隧道”接口，它们的区别仅在于“本地ID：”字段中的设置（将在下面讨论）。
  
  因此，在创建（我称之为）隧道时，无论Kerio将与哪个外部IP地址联系MikroTik，Kerio（出于某种原因）都将激活遇到的第一个接口，并且如果设置中指定了IP地址Kerio一侧的隧道与MikroTik所指的隧道不同，该隧道没有组织。
  
  并且在为所有隧道指示了不同的关键词的情况下，该问题停止了。
• 4.2在“本地ID：”字段中，输入ISP＃1地址池中的IP地址（在示例11.11.11.111中），该地址池分配给MikroTik将访问的Kerio Control＃1 WAN接口；
• 4.3在“远程ID：”字段中，输入FQDN，它是我们的MikroTik从DDNS（IP --->云---> DNS名称）获得的。 此设置使我们不必担心ISP MikroTik如何访问Kerio。
• 4.4在“阶段1密码（IKE）：”字段中，从列表中选择aes128-sha1-modp2048。
• 4.5在“阶段2密码（ESP）：”字段中，从列表中选择3des-sha1-modp2048。
• 注意事项：
  编辑通过“更改...”按钮使用的默认设置；
  使用“科学戳方法”选择两种密码。

• 6.1取消选中“使用自动检测到的本地网络”框；
• 6.2设置“使用自定义网络：”复选框，并将网络地址添加到网络列表中，以“覆盖” Kerio Control后面的本地网络中使用的整个地址范围（在示例中为192.168.0.0/16）。

• 来源-表示我们的MikroTik从DDNS收到的FQDN；
• 目标-防火墙
• 服务-平；
• 您也可以指定IP版本（IPv4），但这不是必需的。
