Topic: Ubuntu, VirtualBox, ports

In Win7 it is installed VirtualBox. In VirtualBox guest machines Ubuntu 17 Desktop and Ubuntu 14 server are installed. Delivery of the server differs from a desktop absence of a graphic jacket. In virtual machines through NAT it is made  port 22001-> 22. Through  it is local  goes to both machines. Configurations  are made similarly at both machines. In  ports are specified true IP, But here from an exterior network it turns out   to be connected only to Ubuntu 17, to 14 - in any way. And ports tried to change, and to disconnect the second guest machine. I do not see a difference in configurations. And  in Win absolutely disconnected.

In virtual machines simply port 22, 22001 is a port on Windows? It, obviously, should be different for different visitors.

I hope two different ports of a host (22001, 22002) for each OS? https://askubuntu.com/questions/392608/ … t-remotely if did not help, the interface can  not on that? If on a host  localhost:22001-> <Your IP>:22221 - helped? jTCPfwd can tunnel though on Windows though on Linux, only java it is necessary.

Ubunta in VirtualBox ceased to work for me normally after update attempt it is Ubunty. One year ago suffered with 16th. It was once again convinced what to contact Linuxes - only time (at least) in vain to lose.

If this  in adjustments Virtualbox it is incorrect - ports have to be different. If in guest machines, 1) what for? 2) through tcpdump check up, on what port connections arrive, and show rules iptables. T> Configurations  are made similarly at both machines.

And ports tried to change, and to disconnect the second guest machine. I do not see a difference in configurations. And  in Win absolutely disconnected. First of all  show an output tcpdump. It is expected at least TCP SYN entering on correct IP (10.0.2.15 if in Virtualbox it is specified NAT and did not change) and on the necessary port (22? 22001?)

Not a variant to deliver "the network bridge", and to refuse virtual  VBox? It, , is sometimes inadequate.
