Vagrant - How to access guest Postgres server from host

I installed a boring box with a postgres server running on a port 5432and added it to Vagrantfile:

  config.vm.network "private_network", ip: "192.168.33.33"
  config.vm.network "forwarded_port", guest: 5432, host: 3333

But when I try to connect to the Postgres server via192.168.33.33:3333

I get this error:

Connection refused and if I try to connect to any port that is not open I get the same error. I ran a port scanner on 192.168.33.33 and it didn't find any forwarded ports open. This is actually what I have in the Vagrantfile:

  config.vm.network "forwarded_port", guest: 8000, host: 8001
  config.vm.network "forwarded_port", guest: 3333, host: 3334
  config.vm.network "forwarded_port", guest: 5555, host: 5556
  config.vm.network "forwarded_port", guest: 5432, host: 3333

  config.vm.network "forwarded_port", guest: 80, host: 8888,
    auto_correct: true

Here are the results of the port scanner:

It doesn't detect ports higher than 995. How to access VM postgres server?

UPDATE: I found a way to connect via localhost (Char suggested) and it seems to config.vm.network "forwarded_port"only forward the port to localhost. Also, I followed this guide : https://pseudoscripter.wordpress.com/2016/04/26/allow-remote-hosts-to-connect-to-postgresql-database-server-on-vagrant-box/

and edit postgresql.confit to add everything to listen on all IPs:

listen_addresses = '*'         # what IP address(es) to listen on;

and modified pg_hba.confto allow guest IP addresses:

host    all             all             192.168.33.33/24        md5

^^ This step probably has nothing to do with why it works localhost:3333. The steps in this guide cannot be continued 192.168.33.33:3333, but I can localhost:3333.

Solved instead of trying to access the server on the guest IP through the port forwarded, I can access it on the guest port, so I can now access the server 192.168.33.33:5432. This didn't work for me when I tried it for the first time, so the steps in UPDATE 1 were required to access it.
