- Obtain the IKE policy used by your gateway device.
- Obtain the IPsec policy used by your gateway device.
- Obtain the ACL rule used by your gateway device.
- Check whether your gateway device can communicate with the gateway devices in the public cloud system.
The commands used on different gateway devices are different. You can run the commands based on your gateway device (such as Cisco, H3C, AR, or Fortinet device) to obtain the preceding required information.
