How does the VIA VPN client detect an untrusted network?
Product and Software: This article applies to all ArubaOS.
VIA detects if it is attached to a trusted and network and avoids activating tunnel (IPsec/SSL if IPsec fails).
Detection performed by attempting http/https HEAD request to the provisioned internal/private IP address of the Aruba Controller.
If VIA_SESSION set included, then attached to trusted otherwise, VIA initiates tunnel (IPsec/SSL if IPsec fails).
