Configure NFS ports

Configuring NFS (Network File System) ports is essential for enabling communication and data transfer between NFS clients and servers securely within a network. NFS relies on specific port numbers for its operations, and ensuring these ports are properly configured is crucial for facilitating file sharing and access.

By default, NFS uses port 2049 for its main operations, such as file read, write, and metadata requests. Additionally, NFS may use other ports for specific purposes, such as port 111 for RPC (Remote Procedure Call) and port 1110 for mountd, the NFS mount daemon.
