How to open remote access via ssh if port forwarding does not work?

Question

SSH

Hello everyone, I tried to formulate the question as correctly as possible.
The task is to provide ssh access to the virtual machine through an external ip.
Through virtual box, port forwarding works, you can connect via LAN. But with the firewall disabled and a dedicated ip from Rostelecom, port forwarding does not work and you can not connect, I attached the photos.
How to fix this or do I need to call Rostelecom?
Thanks in advance!



*port must be opened exactly 2200

Answer 1

Remove the external source in the ip router settings. This is a restriction on incoming ip. Set the parameter there to "any"
Leave the port as it is

Answer 2

ip specified virtual machine?
by default, virtualbox for the guest system creates a dedicated local network and configures nat, blocking access from outside (but the virtual machine will see your network)
configure the network for the virtual machine as a network bridge, in this case, the ip address will be given to it by your router, i.e. the machine will be connected to your local network as usual and already set up redirection on the router to this address
