The Problem is with your NAS applicance. You need a NFS server v3 over TCP.<br />
Your NAS applicance may be running a differer versions or it may be using UDP over IP .<br />
Check the NAS admin guide to configure your NAS to run NFS on UDP port.<br />
Nothing to do with ESX.<br />
<br />
If you want to confirm if it is a problem with ESX or NAS, you can download some NFS virtual applince and try connecting to it, so that you can isolate where the issue is.

Hi,

I am trying to setup my ESX Host running 3.5 to add NFS storage being provided by a Cisco Linksys NAS appliance model NSS6000. When I copy the settings into the "Add Storage" wizard in the ESX host i get the following error and the process fails with "NFS Error: Unable to Mount filesystem: the NFS server does not support MOUNT version 3 over TCP" 

VMWare ESX Host 3.5 NFS Storage Setup on Cisco Linksys NSS6000

VMware, a software company founded in 1998,  was one of the first commercially successful companies to offer x86 virtualization. The storage company EMC purchased VMware in 1994. Dell Technologies acquired EMC in 2016. VMware’s parent company is now Dell Technologies.

VMware has many software products that run on desktops, Microsoft Windows, Linux, and macOS, which allows the virtualizing of the x86 architecture.  Its enterprise software hypervisor for servers, VMware vSphere Hypervisor (ESXi), is a bare-metal hypervisor that runs directly on the server hardware and does not require an additional underlying operating system.
