Host: Arch Linux 64
Guest: Windows 7 Pro SP1 64
VB: 5.1.22 r115126

There is remote server managed from guest VPN.
On guest there is putty tunnel from remote server SSH port to local 722.
So I can access remote through localhost:722 on guest by other putty session.
I am trying to forward this port to host, and there troubles come.
I have tried to access it directly or through NAT forwarding, neither works.
There is no response as if guest:722 is not open.
To contrast I can access both ways to guest:22 (OpenSSH server).

Thank you for any help!

Problem had been solved by remote port forwarding.
on guest:

Code: Select all

 ssh.exe  -R 7722:<remote>:722 <hostuser>@<host>

after it I could do at host:

Code: Select all

ssh -p 7722 root@127.1

and get my desired connection from host to remote.
