Can a static MAC address for the VPN Tunneling virtual adapter be configured? This article explains why this is not supported.
It is desired to assign a static MAC address for the VPN tunneling virtual adapter, either Junos Pulse or Network Connect, due to the requirement of third-party software.
No, it is not possible to have a static MAC address for the VPN Tunneling Virtual adapter.
The virtual MAC for Network Connect will always start with 00:FF and the rest of the MAC is generated dynamically; the Junos Pulse MAC will always be dynamic.
The MAC address of the Network Connect client machine is randomly generated based on a proprietary algorithm.
- Network Connect MAC address changes across reboot. Driver un-installation and installation will also cause Network Connect MAC address to change.
- During Network Connect upgrade Network Connect MAC address may or may not change. This depends on whether driver changes or not. On all upgrades, driver may not change.
