I cannot for the life of my understand why a GUI SSH app would be more complicated to set up than a command line to do the same thing in terminal.

True, once you've puzzled out the unorthodox interface, you can start all your needed ssh services with a click of a button** (**once you wrap your mind around the local client process being called "AVPN Server".) But the same thing is true if you use the freeware CLIX to set up a terminal command to do it, or one of several other free, lightweight utilities. And believe me, if you don't already know how to set up a terminal SSH command to to what you need to do, you're not going to be able to figure out how to get this app to do it.

It's a shame, because the programmer obviously put a lot of work and care into this and the basic idea is powerful. But this is a case of a solution being much more complicated than the problem it's supposed to solve.
