*******************************************
1、清空所有密钥对及PKI TRUSTPOINT
(config)#crypto key zeroize rsa
(config)#no crypto pki trustpoint XXX
*******************************************
2、外部链接
在花生壳官网申请顶级域名，包含txt记录，同时对顶级域名打开DDNS服务

设备配置:
!
ip ddns update method oray
HTTP
  add http://xxx:xxx@ddns.oray.com/ph/update?hostname=www.kagamigawa.tech&&myip=
interval maximum 0 0 1 0
interval minimum 0 0 1 0
!
interface GigabitEthernet1
description WAN
no ip address
pppoe enable group global
cdp enable
pppoe-client dial-pool-number 1
!
interface Dialer1
description WAN
ip ddns update hostname www.kagamigawa.tech
ip ddns update oray host ddns.oray.com
ip address negotiated
ip nat outside
encapsulation ppp
ip tcp adjust-mss 1452
dialer pool 1
ppp pap sent-username xxx password 7 xxx
ppp ipcp dns request
ppp ipcp route default
!
测试下连通性：
C:\Users\Lenovo>ping www.kagamigawa.tech

正在 Ping www.kagamigawa.tech [49.118.72.197] 具有 32 字节的数据:
来自 49.118.72.197 的回复: 字节=32 时间=89ms TTL=242

没有问题继续

3、为域名申请SSL数字证书
在腾讯云中申请免费的数字签名证书

过程中需要进行DNS验证，回到花生壳中添加一条txt记录

下载已签发的数字证书

解压IIS文件夹中的xxx.pfx文件和keystorePass.txt到桌面然后上传到设备的bootflash:

4、安装及检查证书
(config)crypto pki import VPN pkcs12 bootflash:www.kagamigawa.tech.pfx password xxx

检查pki trustpoints
show crypto pki trustpoints
Trustpoint VPN:
    Subject Name:
    cn=TrustAsia TLS RSA CA
    ou=Domain Validated SSL
    o=TrustAsia Technologies
     Inc.
    c=CN
          Serial Number (hex): 0580267F06F29553348E1C185A5EEE2E
    Certificate configured.

检查根证书
