ATP200, SFP to Lan Port?

Hi
My Home Server is hooked directly to the SFP Port on my ATP. The ATP is the DHCP Server for a bunch of Virtual Machines. Now I have to move them somehow to an Server who is connect lets say Lan Port 1 (= P4). For that reason I set up LAN2 and under "DHCP Setting" I choose DHCP Relay and in "Relay Server 1" I put in the IP from the SFP DHCP like 192.168.100.1

When I activate the Rule the hole System drive insane and not asign any IP Adress to any network anymore.

So what is the correct way?

Thanks
