as Orlin already explained, you cannot keep the connection alive when
changing your IP.
While using a VM may be a possible solution, it certainly is an overkill
and eats up a lot of system resources.
I would recommend to take a look screen .
With screen, you can log on to your linux machine, and start all tasks
there in a screen session. When you need to change your ip, detach the
screen session on the remote server, disconnect from the server, change
your ip, reconnect and reattach the screen session. That way, tasks
executed on the linux server keep running even while you are
disconnected from the linux machine, and you can pick up right where you
left when reattaching the screen session.
All this is actually very simple, if you don't know it already, there's
a lot of good tutorials about screen :-)
