About Source MAC Address Override

An internal option has been added that allows you to replace the source MAC address of an outbound or port-forwarded packet with the MAC address specified in a NAT policy. By default, without this option, the MAC address of the output interface is used as the source MAC address of the packet.

This feature is also disabled by default, but can be enabled using an internal setting. Contact SonicWall Technical Support for information about internal settings.
