RDP into VirtualBox on Windows
I have found a not-very-friendly-but-works solution:
In the VM's settings:
- Set the RDP port to anything (it works with 5030)
- Set the network access to NAT
- Go to Network > Advanced > Port redirection, add the following line:
RDP ; TCP ; host's IP ; 5030 ; 10.0.2.15 ; 3389
The host's IP must be the actual host's IP if you want to connect with another computer, or 127.0.0.1 if you want to connect on the host computer.
My VMs all seem to have 10.0.2.15 as IPs, but maybe that's a coincidence. Check that, if it doesn't work.
On the guest OS, check that RDP is enabled: on Win7, right click computer > properties > Remote settings (on the left panel) > Allow connections (I used the "less secure" one)
The VMs downloaded on modern.ie have an "auto-logon" feature that's nice in general, but annoying in this scenario (they might prevent you from logging in). On Win7, run "netplwiz" and check "Users must enter a user name and password". The password of the user can be found here (it's Passw0rd!)
The above answer (by cosmo0) should solve the problem, except if you need authenticated connection. For authentication, choose external in VM Settings > Display > Remote Display > Authentication Method. Then in RDP client, press Show Options and tick Allow me to save credentials. Press connect and it should prompt you with loging/password dialog.
If it doesn't work for you, then create RDP user as follows.
Locate VBoxManage.exe command line tool (in my case it was inC:\Program Files\Oracle\VirtualBox\) and perform following commands while VM is off:
VBoxManage internalcommands passwordhash "your_password"
you will get a hash here. Copy it. Then continue with:
VBoxManage setproperty vrdeauthlibrary "VBoxAuthSimple"
VBoxManage modifyvm "your_VM_name" --vrdeauthtype external
VBoxManage setextradata "your_VM_name" "VBoxAuthSimple/users/your_username"
your_hash
This way your create an RDP user that should work. NOTE, this user is NOT related to any existing users in guest or host os, its for VirtualBox only.
