Console redirect will not work over the internet.  You can install the OS locally, either with a DVD or bootable USB key. 
I have R210 on colocation/ I dont have another server in the same network. I can do power management through ipmitool. I want to be able install Windows 2012 remotely but I only have BMC (no iDRAC express or enterprise). I have USB stick in the server. So basically I can try to upload Windows to the USB and then install it remotely using combination of remote console redirection (to modify BIOS) and RDP (to finalise Windows setup). However I only see that you can connect to the Dell BMC console redirect using either local LAN connection or VPN into the LAN in question or having SOL running on Linux in that LAN... So everything I could find is pointing to local LAN. Is it anyhow possible to run over public internet ?
Is it possible to do remote console redirect over public internet?
