Hello, do I need to install NTP client to sync time for my router as shown here?

Then why SNTP is installed by default istn't it the same thing as NTP?
I enabled SNTP and it doesn't sync anything

RouterOS built-in NTP client works properly.
Try different time servers clesest to you:
http://support.ntp.org/bin/view/Servers/NTPPoolServers

HTH,

Stupid me, I should have created firewall rule to allow ntp packet to be received by router.
Same goes for pings if you want to use Mikrotik router ping utility, This router is very smart.

For anyone else having this problem you should:

Create new firewall rule to accept NTP replies above the deny all trafic rule:

chain: input
protocol: udp
dst port : 123
in interface: wan1 (your WAN interface)
conn state: established

Acction: accept

The router is not "smart". On the contrary, it only does EXACTLY what you tell it to do. If you tell it to drop all, then it will drop all. It doesn't use any intelligence to try to figure out what you want to do. YOU are the "smarts" of the router. It does only what you allow it to do.
