The VPN GTI Editor page provides an easy way to create VPN site-to-site tunnels and displays VPN tunnels that are created on a graphical interface. To access the VPN GTI Editor page, go to CONFIGURATION > Configuration Tree > Multi-Range > Global Settings > VPN GTI Editor.

The page is divided into two main sections:

  • Details Section
  • Canvas Section

The upper section of the VPN GTI Editor page displays all VPN groups, VPN services, WAN Optimization, and VPN root certificates that have been configured on the Control Center.


All information displayed in the Details section is arranged by tabs:

    • dotted line – IPsec tunnel
  • Direction – The direction of the tunnel is indicated by an arrow to the designated tunnel endpoints. The direction of the arrows also indicate the tunnel type:
    • Tunnels flagged with one arrow tip – Active-passive tunnel (the arrow points to the passive tunnel endpoint)
    • Tunnels flagged with arrow tips on both ends – Active-active tunnel
