Login to mikrotik through L2tp over OSPF how to force?

Question

Mikrotik

There is a tunnel in the office white IP in the gray branch (dynamics), Lt2p rises to the office, then ospf is built on top of it, in fact, when trying to access the router from the branch at the internal address, it fails, or rather it succeeds, but we have this picture, i.e. it turns out to enter but the data is not loaded, on a white IP if you pass from the office, then everything goes fine. Where am I missing something?

Answer 1

all my inattention, I indicated 0.0.0.0 on the interfaces, so there was no traffic .....

Answer 2

and if through ssh?
pings to the tunnel ip are not lost? maybe the mtu problem.
PS
There are no configs, telepaths are on vacation.

Answer 3

What does "ospf is built on top of it" mean? OSPF, as it were, is not built, it is turned on on an interface that looks (in some cases) at exactly the same router with OSPF enabled on a similar interface. If there is no connection, then either we don’t need to know about your OSPF, or everything is so tricky there that you can’t figure it out without configs.
Let's start simple:
Firewalls, routes, rules in the mangles of both sides.
