You have to initiate the "get" from the router, acting as a client. Otherwise the router would need to have tftp server functionality, which is not supported.

I could get the config file from the router. I set my router as TFTP server and i use the Get to grab the config file from it. However after i edit what i want i cannot Put back the configuration file into the router.
