Mu5 Posts: 4 Rating: (0)	Hi all, I actually was also wondering if it is possible to the synchronization with an EXTERNAL NTP server. in the configurations, the S7-1200 does not accept IP addresses outside the subnet it is in. I'm really not good in IT and networking stuff, but is it necessary to do some kind of routing for the external NTP (e.g. nist1-ny.ustiming.org / 64.90.182.55 )server or is there another solution? Thanks a lot marwan
