I don't understand why WebFig calls this SNTP IIUC.

Also why can't I use 0.asia.pool.ntp.org instead of IPs? Or am I missing something?

I have a suspicion that your router board is not connected to your ISP while you ran the configuration.
The router cannot perform DNS translations in itself

My router has DNS. It seems that it won't accept a domain name as an argument. Bit crap.

Ping to 0.asia.pool.ntp.org and you know the IP-address

Ping to 0.asia.pool.ntp.org and you know the IP-address

It works, but this is workaround

Don't lose hope. They only recently added this "advanced feature" to VPN clients, including OpenVPN they hate very much. For NTP, which AFAIK they don't hate, so that should be an advantage, it should eventually happen too.

Use the [:resolve] function to set NTP... like this:

I think this doesn't solve the problem in the long term.

The 0.asia.pool.nts.org link refers to a pool of IP's of NTS servers. This means if the IP of a NTS server goes offline, the domain (0.asia....) will automatically link to the IP address of another NTS server.
The IP of the domain is dynamic.

But I'm not sure...

Because programmers at MikroTik are lazy . This functionality is so simple to implement and was so many times requested that there is no other explanation for this.

Also: most RouterBoards don't have clocks build in, so SNTP client could be enabled by default with 0.pool.ntp.org and 1.pool.ntp.org set as default servers. So simple and practical.

The easiest solution is to use the scheduler to update the NTP servers every X minutes. Something like this: http://forum.mikrotik.com/viewtopic.php ... 06#p415437

I just found that SNTP Client in Winbox accepts domain names and resolves them to IP addresses. I think it wasn't possible in v 6.8 (when I last tried that ).
