if you declare the server address with an IP on the server line, the IP from server state file will never be used. If you want to use it you need to declare the server address with a name and not an address, like this: server-template rdp 1-5 foo.bar disabled init-addr last,1.2.3.4 this will set the IP to 1.2.3.4 by default, and you can change it with the stats socket. when you reload, you will use the IP from the server state file. cheers, Jérôme
