ros routeros ikev2 ipsec传输模式配置

admin

先介绍下环境拓扑图：

1.1.1.1并不是真实的公网IP，而是一个城域网IP，而2.2.2.2是真实的公网IP，所以在这里做ipsec的服务端

1.1.1.1被nat出去以后的IP是b.b.b.b

客户端配置：

1. /interface bridge
   
2. add name=bridge1-wan
   
3. /interface ethernet
   
4. set [ find default-name=ether1 ] name=ether1-wan
   
5. set [ find default-name=ether2 ] name=ether2-wan
   
6. set [ find default-name=ether3 ] name=ether3-wan
   
7. set [ find default-name=ether4 ] name=ether4-wan
   
8. set [ find default-name=ether5 ] name=ether5-lan
   
9. /interface pppoe-client
   
10. add disabled=no interface=bridge1-wan name=pppoe-out1 password=123456 user=\
    
11. 02501017724
    
12. /ip ipsec mode-config
    
13. add name=cfg1 responder=no
    
14. /ip ipsec profile
    
15. add enc-algorithm=aes-256 hash-algorithm=sha256 name=ikev2-profile1
    
16. /ip ipsec peer
    
17. add address=2.2.2.2/32 exchange-mode=ike2 name=ikev2-peer1 profile=\
    
18. ikev2-profile1
    
19. /ip ipsec proposal
    
20. add auth-algorithms=sha256 enc-algorithms=aes-256-cbc name=ikev2-proposal1 \
    
21. pfs-group=none
    
22. /interface bridge port
    
23. add bridge=bridge1-wan interface=ether1-wan
    
24. add bridge=bridge1-wan interface=ether2-wan
    
25. add bridge=bridge1-wan interface=ether3-wan
    
26. add bridge=bridge1-wan interface=ether4-wan
    
27. /ip address
    
28. add address=192.168.90.100/24 interface=ether5-lan network=192.168.90.0
    
29. /ip dns
    
30. set servers=114.114.114.114
    
31. /ip firewall nat
    
32. add action=accept chain=srcnat dst-address=10.10.2.0/24 src-address=\
    
33. 192.168.77.0/24
    
34. add action=accept chain=srcnat dst-address=10.10.2.0/24 src-address=\
    
35. 192.168.90.0/24
    
36. add action=masquerade chain=srcnat out-interface=pppoe-out1
    
37. /ip ipsec identity
    
38. add generate-policy=port-strict mode-config=cfg1 peer=ikev2-peer1 secret=\
    
39. 12345678
    
40. /ip ipsec policy(这里要斟酌下1.1.1.1这里的IP怎么写，因为这个IP是城域网IP，nat出去以后并不是这个ip，nat出去以后是b.b.b.b这个ip)
    
41. add dst-address=10.10.2.0/24 level=unique proposal=ikev2-proposal1 \
    
42. sa-dst-address=2.2.2.2 sa-src-address=1.1.1.1 src-address=\
    
43. 192.168.90.0/24 tunnel=yes
    
44. /ip route
    
45. add distance=1 gateway=pppoe-out1
