Seafile firewall / port problem on docker


I’m running Seafile into docker on my Synology NAS.

On the docker compose I have

    image: seafileltd/seafile-mc:latest
    container_name: Seafile
    restart: always
      - "7000:80"
      - "8080:8080"

It’s running along a Mariadb and memcached on the stack.

I then use a reverse proxy, localhost:7000 to 443.

Everything works fine, but as soon as I turn on the NAS firewall the access is down.
I opened the 443 of course (my other reverse proxies are working).

But I don’t get what are the other ports that I need to open.

Thanks in advance !
