VPN Mobility can only be supported using an AT&T SIG VPN Server as the tunnel terminating device for
AT&T VPN Tunneling Services or the AT&T VIG with the AT&T Network-Based IP VPN Remote Access
service.
VPN Mobility can only be supported using single-sign-on as the authentication method.
VPN Mobility will not work if the device enters the low power/hibernation state. If the user’s device
enters a low power or hibernation state the connection is automatically terminated.
Configuration
The VPN Mobility feature requires:
• The VPN Mobility option must be enabled in the AT&T administration server. See Appendix A
Central Configuration for additional information.
• The VPN Mobility Duration option must be set to a value greater than zero in the AT&T
administration server. See Appendix A Central Configuration for additional information.
Advanced Configuration
By default the VPN Mobility feature will sustain the VPN Connection using the default route. If multiple
paths are available the prioritization is Ethernet, Wi-Fi, Mobile, Dial.
Users and administrators can define a custom network interface prioritization using the Login Properties
dialog. Select Login Properties, VPN Mobility tab, enable the checkbox next to Override defaults, enable
the checkbox next to Operate in VPN Mobility mode, select Create my own network interface
prioritization and click Configure.
