If attempting to SSH to a remote Windows 11 system using a ZeroTier network managed address leads to a connection timeout then a possible problem is that the ZeroTier network has been configured as a PUBLIC network on the target machine, changing this to a PRIVATE network might resolve the problem. The following Powershell commands can be used.
## To check public/private setting
Get-NetConnectionProfile | Where-Object "InterfaceAlias" -like "Zero*"
## To set all ZeroTier networks to Private
Get-NetConnectionProfile | Where-Object "InterfaceAlias" -like "Zero*" | Set-NetConnectionProfile -NetworkCategory Private
