Modifying a VPN Connection
Scenario
A VPN connection is an encrypted communications channel established between a VPN gateway in a VPC and a customer gateway in your on-premises data center. You can modify a VPN connection when required.
Procedure
- Log in to the management console.
- Click in the upper left corner and select the desired region and project.
- On the homepage, choose .
- In the navigation pane on the left, choose .
- On the VPN Connection page, locate the VPN connection to modify, and click Modify VPN Connection or Modify Policy Settings.
- Modify VPN connection parameters as prompted.
For VPN connections in policy template mode, you can modify the policy settings on the VPN Gateways page, instead of on the VPN Connection page. For details, see Modifying the Policy Template of a VPN Gateway.
- Click OK.
If you change the PSK or modify the IKE or IPsec policy of a VPN connection, ensure that the new configurations are consistent with those on the customer gateway. Otherwise, the VPN connection will be interrupted.
Only some of the parameters take effect immediately after being modified, as described in Table 1.
