However, be mindful, that this needs to go to the router that is attached to the entry point where your request for "http://teste.teste.org" would arrive to, that is the one that corresponds port 80.
I also have a suspicion that this may be XY-Problem, in particular I'm assuming from your post that:
You want traefik to handle all your incoming requests, that is no request goes directly to dspace
Therefore you configured traefik to listen on both 80 and 8080
You configured you router that routes to dspace server to use the entry point that is associated with 8080 port
