Please refer to following link.
My router is MT3000, what your means is MT3000 beta firmware?
[update] I download the beta firmware, still cannot find openvpn config, only zerotie, tailscale, where is the openvpn client config?
It has been mentioned a few times on the forums that the routers for the China market omit VPN. Is this the case with your router?
So, where can I download the oversea version firmware?
@Alzhao may possibly be able to assist.
