Static Ip for IpSEC/L2TP Client Mikrotik possible?

Hi, I want to know is this possible to add an static ip address for L2TP client ?
I have a softether l2tp server and its doesnot support mac-ip binding or static ip.

When i am stopping the dhcp server the server is giving an error could not determine remote ip address.
Please help.

/ ip firewall nat chain forward src- add x.x.x.x/32 action=src-nat to-address: “static ip address”

That is a firewall mangle tool, the main problem is how to add static IP that we do in windows>properties>ipv4 and then input all the ip ,subnet ,defafult gateway etc…

Here is what I added after dhcp lease from server(1st ip added manually)
Please help
