Hello Rupert, I might hazard a guess that you open up Windows Firewall with advanced security in windows pro 10 and allow the entire dynamic range of ports that the port mapper might divert the client to, or simply allow all traffic to / from the NFS server on the windows clients (just to test)
I have seen issues with Windows Firewall and some updates ( on windows services that use RPC extensively such as MS SQL / SQL Browser) if your windows 10 environments are controlled by active directory you may have to set the windows firewall settings in Group Policy (any more than this and im wandering dangerously off OpenBSD Topic ) :) I hope this helps Thanks On 14 February 2018 at 15:52, Rupert Gallagher <r...@protonmail.com> wrote: > This is a recurring problem that is proving hard to fix.
