Client change ip

Post by lexeyFan » Mon Jun 08, 2020 11:39 am

I have a server on Ubuntu and a number of clients on Windows and routers as clients, there are no problems with routers.
Windows 1 time per day automatically reconnects and receives the first free ip (this occurs if I am connected to the client via RPD, in other cases everything works fine), if I reconnect manually, it gets the address I assigned, tell me how to solve this problem?

Set --verb 4 in your server config and check that your CCD file is used when the client connects.
