Hello,
must port 22 on Windows server be enabled in a bidirectional way to establish a connection with RSA key exchange?
I have a Linux server on a vlan and a Windows server on another vlan, those vlans are connected thru a firewall, where port 22 is enabled from Linux server to Windows server unidirectionally.
Connection with user and password works, but not with RSA key exchange: is the problem located on port 22 unidirectional enabling?
Thanks in advance.
