Sun used version 1 only for in-house experimental purposes. When the development team added substantial changes to NFS version 1 and released it outside of Sun, they decided to release the new version as v2, so that version interoperation and RPC version fallback could be tested. Version 2 of the protocol (defined in RFC 1094, March 1989) originally operated only over User Datagram Protocol (UDP). Its designers meant to keep the server side stateless, with locking(for …

Mar 14, 2018 · Most of the time the GroupWise Disaster Recovery and the GroupWise system are in the internal network, and there is no need to open up the NFS ports for the firewall. If moving the GroupWise or GroupWise Disaster Recovery servers to a DMZ, however, the ports will need to be opened up on the firewall. For specific ports to be opened up for GroupWise Disaster Recovery click here.

03.03.2020 · NFSD The NFS Daemon runs only on NFS Servers (not on clients). It already runs on a static port, 2049 for both TCP and UDP. Firewalls should be configured to allow incoming packets to this port on both TCP and UDP. This firewall exception is only needed for packets incoming to a NFS Server. NOTE: For NFS v4, 2049 is the only port needed.

Network File System or NFS is a file system protocol that allows users to share directories and files over a network. The NFS protocol is similar to the Samba protocol. However, unlike Samba, NFS provides an encryption mechanism and authentication. What Ports does NFS use is explained in this article.

NFS requires rpcbind, which dynamically assigns ports for RPC services and can cause problems for configuring firewall rules. To allow clients to access NFS shares behind a firewall, edit the /etc/sysconfig/nfs configuration file to control which ports the required RPC services run on. The /etc/sysconfig/nfs may not exist by default on all systems.

Port 111 (TCP and UDP) and 2049 (TCP and UDP) for the NFS server. There are also ports for Cluster and client status (Port 1110 TCP for the former, and 1110 UDP for the latter) as well as a port for the NFS lock manager (Port 4045 TCP and UDP). Only you can determine which ports you need to allow depending on which services are needed cross-gateway.
