Thank you very much warmonFor a Single machine, the loopback IP address is fine as that's the client software looking at the host machine (you could put your current machine ip address in but you'd be doing the same exact thing as the loopback address. So it makes the process pointless.)
The real reason why you'd want to mess with the IP address is if you had multiple computers running F@H and wanted to control them from one system. (Remote Connection/Access F@H called it awhile back).
He's an old video I did demoing it back in 2012
(Sorry, never gotten around to fixing the audio issue on this video but it should still show what that the software is able to do.)
Sure the pc is in a lan but is the only running F@h.
I thought it was better using machine ip address for that reason,
in any way now after reinstalling some time the F@h client I noticed the installation program doesn't ask to install for the current user or for all user. I read onto F@H forum they have an issue about this.
And for this reason I will stop for a while till they resolve this problem and also giving task to all user.
Hoping to being helpfull for covid in near future, I thank you again
