title: Can we change GCP Cloud VPN default parameters?
body: <p>I am trying to set up a site-to-site IPSec tunnel with Google Cloud Platform.</p>
  
  <p>The On-Prem data-centre engineers have asked if we can increase IKEv2 Phase 1 lifetime from 36,000 to 86,400 seconds.</p>
  
  <p>However, it does not appear to be a setting that can be changed; not via GCP Console and not in Terraform/Ansible docs. Does any one know any API instructions to modify this?</p>
  
  <p>The Params are shown on the link below:</p>

  <p>Will greatly appreciate any help/suggestion on this.</p>
  
  <p>thank you</p>
