Mikrotik network access is defective. What to do?

Question

SSH

There is a Mikrotik heX router in the apartment, a file server with Debian and Netgear R7000 is connected to it ... to which a laptop is connected in a chain. Mikrotik acts as a gateway with pppoe connection to domra. When he was not there and netgir himself performed this role, everything was okay.
Now the main problem is that there is no access to the network via SSH (to the file server) and access via SAMBA does not work correctly (it asks for a password for ALL resources and at the same time rejects any login data).
Moreover, I successfully ping the server from the laptop... and there is a network on the server itself... but there are no accesses. What could be? Help me please.

Answer 1

In Mikrotik, in the IP -> DNS tab, there is a "Static" button, register your hosts there.
In order for a certain host to have a permanent IP in DHCP, there is also a "Make static" button in Leases.
Well, accordingly, in the DHCP settings, you must issue it as DNS your router

Answer 2

Then such a question. So that I can connect by domain names, I need to register static DNS records. Right? Is it possible to make them "pull up" from the DHCP server?

If we are talking about linux, then you can connect by netBios names. To do this, you need to install libnss-winbind and winbind on linux and add it to /etc/nsswitch.conf in the hosts - wins line.

Answer 3

The issue is resolved ... I'm just an idiot ...
Although I was connected to the netgear via WiFi, the "main gateway" parameter of the wired mesh was set manually and pulled up to the WiFi adapter (I don’t understand why). As soon as I removed everything to the "automatic", everything was fine right away.
