VPN2S with V1.20(ABLN.1) and V1.20(ABLN.2)

So I though with V1.20(ABLN.2) this was fixed turns out its not.

So you set a MAC for WAN1 and it sends out DHCP the default MAC Discover and set MAC when it should send only the set MAC.

    After checked it internally, the customize MAC on Wan page mainly supports on USG 20 VPN and above models but not on VPN2S. It is incorrect GUI layout on VPN2S. 

    Regarding to this scenario, you can consider to implement it on USG 20 VPN.

    I don't follow? What should happen is I set the MAC enable WAN1 and thats the MAC the DHCP client sends for a IP.

    Currently if you set the MAC and enable the DHCP client send from the default MAC and set MAC for a IP. Are you saying the VPN2S can't send DHCP from the set MAC only?

    Still think this is a bug unless its hardware offloaded for doing ARP and DHCP only the set MAC should be the source on a given interface.
