Docker-compose mount volume nfs

Hi all,
sorry for the absence but I had personal problems. I managed to figure out, perhaps, the problem of missing mount for the NFS partition.

This is the docker-compose:

version: "3.8"
volumes:
  neonfs:
    driver: local
    driver_opts:
      type: nfs
      o: "addr=172.26.209.22,rw"
      device: ":/space/home/user/varwwwhtml"
services:
  web:
    build:
      dockerfile: ./Dockerfile
    ports:
      - "80:80"
    environment:
      - FlexDebug=on
    volumes:
      - neonfs:/var/nfs
      - type: bind
        source: ./examplephp7
        target: /var/www/html/

and i receive “permission denied”. I’ve watched the NFS logs and found this:

refused mount request from 172.26.208.50 for /space/home/user/varwwwhtml (/space/home/user/varwwwhtml): illegal port 60139

My DevOPS says that all port greater than 1024 are blocked for security reason. I can change port for NFS?

Thanks a lot.
