Send configuration to local clients from server?

hello, i installed urbackup server on ubuntu server, and client to some windows pc.
How can i send configuration to all clients from server only lan, no internet client?
thanks

Hi, if it s on the same subnetwork , thats defined as being able to do udp broadcast
and if the cliet never contacted any other server before

Then you have nothing to do, client will be detected and wil start to show up on the server
