Which ports do I need to open in the firewall to use NFS?

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).

What port does NFS use Linux?

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.

What is port 445 commonly used for?

It's a transport layer protocol designed to use in Windows operating systems over a network. Port 445 is used by newer versions of SMB (after Windows 2000) on top of a TCP stack, allowing SMB to communicate over the Internet. This also means you can use IP addresses in order to use SMB like file sharing.

What is NFS in Linux?

A Network File System (NFS) allows remote hosts to mount file systems over a network and interact with those file systems as though they are mounted locally. This enables system administrators to consolidate resources onto centralized servers on the network.

Is NFS secure?

NFS itself is not generally considered secure - using the kerberos option as @matt suggests is one option, but your best bet if you have to use NFS is to use a secure VPN and run NFS over that - this way you at least protect the insecure filesystem from the Internet - ofcourse if someone breaches your VPN you're ...

Does NFS support NAT?

The NFS server is accessible in the intranet. A NAT runs on a workstation with FreeBSD or Linux, which is a node in the intranet. Multiple NFS clients are in a private LAN behind the NAT. Routed or Bridged network is not preferred in order to keep the clients invisible outside the NAT.

What is the port number for SMB?

As such, SMB requires network ports on a computer or server to enable communication to other systems. SMB uses either IP port 139 or 445. Port 139: SMB originally ran on top of NetBIOS using port 139.
