Allow ssh protocol through win 10 firewall

Question

I have a workstation with Win 10 on which I installed OpenSSH server. If I try to connect to it (from another machine with Win 10 using ssh in a command prompt) I see it gives the following error:

ssh: connect to host Test3 port 22: Connection timed out

On wireshark Syn packets are sent but no answer is received back. If I dissable Windows firewall on destination then connection is established.

I want to leave the firewall enabled and disable only ssh port.

Answer 1

You can easily use netsh.exe.

netsh advfirewall firewall add rule name="Open SSH Port 22" dir=in action=allow protocol=TCP localport=22 remoteip=any

You can also change remoteip to a specific host:

remoteip=any|localsubnet|dns|dhcp|wins|defaultgateway|<IPv4 address>|<IPv6 address>|<subnet>|<range>|<list>

Answer 2

I found on microsoft site a link which allow to do it using graphical interface. I solved my problem performing the following steps as administrator:

• Open the Group Policy Management Console / File/ Add snap-in / Windows Defender Firewall with Advanced Security(or Windows Settings/ Windows Defender Firewall / Advanced settings).
• Inbound Rules / Actions / New rule
• Rule Type / Port / Next
• TCP / Specific port: 22 / Next
• Allow the connection / Next / Next
• Name / Open ssh port 22 / Finish
