一、实验架构及需求

1.1实验架构图

1.2实验需求

已知，公司的openvpnclient可以成功连接aws的openvpnserver的内网服务器，这是一组openvpn client-server；
需求一： 在自建机房架构openvpnclient，使得IDC机房内网gpu服务器可以双向连通aws内网服务器；
需求二： 通过aws的openvpnserver的client to client配置使得IDC机房client可以和公司client实现数据互通。

二、awsopenvpn-server配置并启动

  22. #成功互通

4.3添加路由实现openvpn-server内网服务器和openvpn-client内网服务器的互通

正常情况下开启了openvpn-server和openvpn-client就可以实现openvpn-server和openvpn-client私网间的互通。但是如果openvpn-server想要找到openvpn-client通以局域网下的其他主机，还需要在openvpn-client子网服务器添加一条路由规则。因为即使发送的数据包可以到达openvpn-client通一局域网内的其他服务器，这些服务器并不知道怎么发回来。

  1. #tcpdump抓一下包
  2. root@gpuserver004:/home/zhangsiming# tcpdump -v icmp
  3. tcpdump: listening on enp14s0, link-type EN10MB (Ethernet), capture size 262144 bytes
  4. 10:59:45.181306 IP (tos 0x0, ttl 62, id 42159, offset 0, flags [DF], proto ICMP (1), length 84)
  5.     172.31.40.247 > 11.11.22.4: ICMP echo request, id 7117, seq 48, length 64
  6. 10:59:45.181343 IP (tos 0x0, ttl 64, id 13077, offset 0, flags [none], proto ICMP (1), length 84)
  7.     11.11.22.4 > 172.31.40.247: ICMP echo reply, id 7117, seq 48, length 64
  8. #可见，需要把回程的目标地址172.31.40.247发送给openvpn-client处理才行
  9. root@gpuserver004:/home/zhangsiming# route add -net 172.31.0.0/16 gw 11.11.22.100
  10. #添加上面这条路由即可。

同理，在aws上面，也需要设置回程路由。

4.4测试

  1. #IDC内网服务器pingaws内网服务器
  2. zhangsiming@gpuserver004:~$ ping 172.31.40.247
  3. PING 172.31.40.247 (172.31.40.247) 56(84) bytes of data.
  4. 64 bytes from 172.31.40.247: icmp_seq=1 ttl=62 time=59.9 ms
  5. 64 bytes from 172.31.40.247: icmp_seq=2 ttl=62 time=30.2 ms
  6. 64 bytes from 172.31.40.247: icmp_seq=3 ttl=62 time=30.2 ms
  7. ^C
  8. --- 172.31.40.247 ping statistics ---
  9. 3 packets transmitted, 3 received, 0% packet loss, time 2002ms
  10. rtt min/avg/max/mdev = 30.254/40.160/59.955/13.997 ms
  12. #aws内网服务器pingIDC内网服务器
  13. root@172:/# ping 11.11.22.4
  14. PING 11.11.22.4 (11.11.22.4) 56(84) bytes of data.
  15. 64 bytes from 11.11.22.4: icmp_seq=1 ttl=62 time=30.2 ms
  16. 64 bytes from 11.11.22.4: icmp_seq=2 ttl=62 time=30.2 ms
  17. 64 bytes from 11.11.22.4: icmp_seq=3 ttl=62 time=30.2 ms
  18. ^C
  19. --- 11.11.22.4 ping statistics ---
  20. 3 packets transmitted, 3 received, 0% packet loss, time 2002ms
  21. rtt min/avg/max/mdev = 30.201/30.241/30.279/0.031 ms

成功实现互通，实验完成。
