How to forward different domains to permanent ip: different port?

Question

Domain Name System

Three domains are set to the same dedicated ip:

test1.com
test2.com
test3.com

And it is necessary that each domain be redirected to a specific port:

from test1.com to 1.2.3.4:8080
from test2.com to 1.2. 3.4:7070
from test3.com to 1.2.3.4:6060

How can I do this without too much difficulty and crutches?

The server is running on Ubuntu 20.04
