Hello all! I recently got a job for CumulussIT as a PC Technician. Turns out, they operate a WISP too! and my boss charged me with solving random reboot issues on our routers. So i started googling (Keep in mind that i didn’t even know Routerboard existed a few weeks ago) and i started parsing the logs, but as everytime the router reboots, the date/time changes and it’s very difficult to understand the meaning of the logs, because i can’t see the relation between diverse events. So i googled some more and found the answer in the NTP client that is included with Mikrotik.
Then i set up the NTP client to synch with 2 Argentine servers i KNOW for a fact they work okay.
[admin@Cerro2] /system ntp client> print
enabled: yes
mode: unicast
primary-ntp: 200.80.32.172
secondary-ntp: 190.2.0.201
dynamic-servers:
status: started
[admin@Cerro2] /system ntp client>
But the clock doesn’t synch 
So i said " Just to try, let’s use a PC as a NTP server"
So i followed this tutorial:
Then i set the IP of my router to be in the same range as the PC, and disabled Windows Firewall to let packets come thru and the NTP server synchs with my PC.
So i tought “Hey, maybe for some reason the router can’t connect to an NTP server outside my local network”
So i tried this on my PC:
Microsoft Windows [Versión 6.1.7600]

C:\Users\oficina>ping 200.80.32.172

(0% perdidos),
Tiempos aproximados de ida y vuelta en milisegundos:
Mínimo = 166ms, Máximo = 222ms, Media = 180ms

So, from my PC i can reach the time synch server, but when I try that on the router, i get this:
[admin@Cerro2] > ping
address: 200.80.32.172
HOST SIZE TTL TIME STATUS
no route to host
no route to host
no route to host
no route to host
no route to host
no route to host
sent=6 received=0 packet-loss=100%
[admin@Cerro2] >
So, evidently, from the router, i can’t reach the NTP server.
I have checked firewall, services, everything, seems okey, but still the router can’t access the NTP server and can’t find a solution to this problem. I have googled a lot but can’t find a solution
I am sure that i am missing something that is pretty obvious lol… so ANY help would be greatly appreciated, i am stuck and can’t progress. But with a little pointing in the right direction i am confident i can learn more and become proficient ith Mikrotik routers.
cheers
) on the right direcion.
