3g modem / IP change / OpenVPN

Hi guys,
I’m newиуу to mikrotik and routing etc, so sorry for mb silly text in advance.
So, I use it in that way:
3g modem is connected to Mikrotik (only, no ethernet)
Mikrotik is connected to Amazon server as a ovpn client.
My computer is connected to Amazon server as a ovpn client too, and I have an IP from 3g connection. So I can surf internet with data from 3g. (was pretty hard to do)
I need to change IP address of my connection few times per day. I can do this by putting command to terminal

/interface disable ppp-out1;/interface enable ppp-out1

As you understand, for that time I am disconnected. And everything worked, but ovpn “understands” that there is no connection only after 2 minutes, and reconnects.
So if I want to change IP address, in my case I need to wait around 3 minutes.
How can I short that time?

Hi.

Terminate the ovpn-session too, when you disable the ppp-out1.
