SoftEther VPN User Forum

When the user object is using the standard user authentication, you need to write the arbitrary virtual MAC address on the "Note" field on the user object. For example, the "Note" field will have the MAC address format which starts with "MAC:" followed by a 6-bytes ASCII-encoded HEX string, such like "MAC:ae:00:00:00:00:01"...

...You can fix each L3 VPN user's virtual MAC address with the above solution. Therefore you can fix the user's IP address by configuring the static IP address reserve list hosted by the existing DHCP server (e.g. Linux dhcpd or Windows DHCP Service) on the target local-area network which the Virtual Hub is connected with the Local Bridge function. To fix the IP addresses assignment by the DHCP server you need to configure the "Static IP address reserve list" function (the function name may vary on each DHCP server product). You need to refer the document of your DHCP Server to configure the static IP address reserve list.
