I use below console command, "Unifi PPPoE" is my pppoe dialer interface, you need to replace it with your interface name.
- interface=bridge-local (bridge-local is my data vlan bridge, replace with your data vlan bridge name)
I have problem with some site like lowyat, therefore i temporary disable it. Didn't really spend extra time checking it.

Can I use this method for TIME dotcom? Or TIME does not yet support for IPv6 in mikrotik?
