telnet <machine IP> 497
Resources
Retrospect for Windows and Retrospect for Mac both support protecting computers over a VPN. It requires the correct networking setup and workflow within Retrospect.
The Retrospect engine must be able to reach the client:
Ensure port 497 is open.
Find the direct IP of the client computer.
To ensure the computer is protected moving forward, configure the VPN software to assign a static IP to the computer.
Go to Clients.
Add client via "Direct IP".
Try to "ping" the computer from the engine computer
Double check the IP you typed within Retrospect is the same as the direct IP of the computer.
Testing from the engine side:
telnet <machine IP> 497
If it connects, you will get a black screen, press control and the ']' key (that is the right square bracket character) to exit.
If it does not, you will get a message similar to:
Could not open connection to the host, on port 497: Connect failed
Note: Telnet is not installed on Windows by default. To install it from the command line, enter:
pkgmgr /iu:"TelnetClient"
