Upgrade Workflow
VIA checks for upgrade requirements during the login phase. There are two types of upgrade process: Minimal
Upgrade and Complete Upgrade.
Minimal Upgrade
This type of upgrade is initiated for bug fixes and some minor enhancements which requires only some
components of the client to be upgraded. When a VPN session is active the upgrade binary is downloaded by VIA
from the controller. After the active VIA connection is terminated, the upgrade process is started and the client is
upgraded. This type of upgrade does not require a system reboot.
Complete Upgrade
This requires an upgrade to VIA and its underlying network drivers. This type of upgrade requires a system reboot.
VIA downloads the upgrade binary from the controller and displays a message about upgrade process after the
connection is terminated for that upgrade. The user can choose to proceed or cancel the upgrade process. If the
user chooses to upgrade, a system reboot is automatically executed. If the user cancels the upgrade, VIA will
prompt the user for an upgrade every time the user terminates a VIA session..

Configuring the VIA Controller
VIA configuration requires that you first configure VPN settings and then configure VIA settings. See Chapter 17,
“Virtual Private Networks” on page389 for information on configuring VPN settings on your controller.
Before you Begin
The following ports must be enabled before configuring the VIA controller.
TCP 443—During the initializing phase, VIA uses HTTPS connections to perform trusted network and
captive portal checks against the controller. It is mandatory that you enable port 443 on your network to allow
VIA to perform these checks.
UDP 4500—Required for IPSec transport
UDP 500—Required for VIA 1.0 on Mac OS
