Port forwarding on zte

I have configured nextcloud on my Freenas, and I want to access it remotely. I have redirected ports 80, 443 and 8282. However, I can´t access it remotely,
I have forwarded ports 80 and 443 to nextcloud ip
I have forwarded port 882 to my FreeNAS IP
I use a DDNS set up and configured as well on my router and FreeNAS
