Looking for a "fing"-like program who can find all units on the other end of my openvpn connection

[Mike A.]

I just discover something on my asus router at home. The client list is 11, but clicking on it I only get 8 units. Some units don't show. Choosing Client List give me 8. It seems that the difference is my internet radio connected to a wifi extender and verisure home station connected to another wifi extender. Fing found all 11 and 3 "passive" too.

Instead of clicking "View List" try clicking on the image of a computer in a circle above that. It will bring up clients in the box to the right. That list doesn't always include everything for whatever reason.

Also if you enable the guest network (even if you don't use it and devices aren't on it) then it will find some devices that it won't pick up otherwise with more recent versions of firmware. Not sure why but it works.
