router RB2011UiAS-2HnD port 22

Hello everybody!
I have problem with port 22 on this router. I try to connect with ssh from LAN to outer IP on port 22 - doesn’t connect, only ‘Connected time out’, I try connect with ssh on port 22 from LAN to router console, this same doesn’t connect. But if I change ssh service port to 2222, I can connect to router console. Connect with telnet to router (port 23) is work.
If I connecting from public IP to IP in LAN on port 22, 3307 etc. I can connect.
Only if I try connect from LAN to outer IP on 22 port I can’t.
That is typically behavior for this router?

Is there any other routers between you and the lan facing port when trying to connect with ssh?

Also is there any filter rules setup on the router?
