Hi, Currently the network is completely isolated but I did hear rumours that the master device may in future have a dedicated link to a server that could potentially be running an NTP Server. Not sure if this will ever happen but I will use stratum 5 just in case. You say this is default so if I use "server 127.127.1.0" there is no need to have the fudge statement?
Cheers, Martin.
