Configuring VPN IPsec vShield Edge to Mikrotik
Not like with another common router platform, configuring VPN IPsec of vShield Edge (vCloud Director) tunneling with mikrotik Router is not easy, because the VPN parameters on vShield Edge are so limited. so we have to do adjustment for VPN Ipsec parameters which exist provided by peering devices; such as DH-Group, lifetime, PFS Group, etc which exist on Mikrotik, Cisco ASA, Checkpoint, pfSense, Vyatta, and another Routers platform.
For this LAB, i will perform setup VPN connection between vShield Edge on vCloud Director with Mikrotik RouterOS based on the topology below :
Based on any sources from internet about compatibility configuration VPN on vShield Edge, actually there are some parameters which being template configuration that have to applied on peer devices (mikrotik)
Configuration on vShield Edge
For the first, I have to setup VPN configuration on vShield Edge (cloud site) with the configuration below :
Configuration on Mikrotik Router
We have to configure VPN IPsec on Mikrotik Router which adjusted with suitable parameter on vShield Edge. i have found the fix parameters for this Mikrotik and already tested too with the success result and stable connection.
All of the scripts below are adjusted with the topology above, so you can just copy this command that already fixed to Mikrotik Console and change the parameters which highlighted with underline, and then adjust it with your network details.
=================================================
type /ip ipsec export in console from mikrotik, then check and verify all of parameters, is it already input correctly.
So, let's perform testing in both side by test ping from LAN user in Cloud (vShield Edge) site to LAN user in another (Mikrotik) site and do the opposite. why ? because tipically the IPsec will be up soon after triggered by flowing traffic between site (in this case is trigger by ping)
I have ran these steps in my LAB, and tunneling between vShield Edge to Mikrotik success established.
Let try my steps and let me know if you get the problem.
Please give your input, comment, or anything that would be improve me :)

For the first, I have to setup VPN configuration on vShield Edge (cloud site) with the configuration below :
- Name : VPN to Office (name of VPN Profile) and then check enable button
- Description : Put the description of VPN Profile*
- Tunnel to : a Remote Network
- Peer IP Address : 202.179.188.32 (IP Public or IP WAN of Mikrotik)
- Peer Gateway : 172.16.0.1 (IP address which attached on interface LAN Mikrotik and acts as a gateway)
- Peer Subnet Mask : 255.255.255.0 (Subnet mask for LAN/internal Network Mikrotik)
- Encryption Protocol : 3DES
- Shared Secret : 123KarenaAllahlahKitaKuatDanKitaMampu (at least minimum 32 character, and must be same in both site)
- Show key : Optional to ensure the shared-key which typed is correct
- MTU : 1500 (use default value)
