Last updated: Aug 07, 2025

Prerequisites and Guidelines

  • Full Admin user role. For more information, see Manage Accounts.
  • Set up the VPN profile. DNS and DDNS settings are part of the General settings when setting up VPN profiles. For more information, see Step 1 – General Settings of the VPN profile section.
  • When setting up VPN profiles, check the DDNS Servers updates option to update the mappings of domain names to IP addresses when a remote user's network IP address changes.
  • When setting up VPN profiles, the DDNS Servers setting defaults to Region specified, meaning that the VPN profile uses the DDNS specified for the region. This is the default behavior across all regions.
  • (Optional) Change the default to Custom specified and map DDNS servers to a different server pair for a VPN profile.
  • (Optional) Change the default to Custom specified selectively for any region, or map all regions to use the same DDNS server pair.
