ufw why are these ports open?

Asked by bas

I just enabled ufw I did:

sudo ufw default deny
sudo ufw enable

Then I did a nmap on my public IP-adres and it shows the following ports a open:

443/tcp open https
49152/tcp open unknown
49153/tcp open unknown
49154/tcp open unknown

Is this normal?!

Thanks in Advance
