Have a handy little unit, think it's this one,
http://exemys.com.ar/beta/english/pr...Be/index.shtml
I have given it a fixed ip, and have port forwarded port 23 on my router to point to this unit.
I have it wired up, to switch on/off my heating system etc.
I have a telnet app on my iphone and iPad and macro's set up, so I push a button on either of them and it tells my boiler "switch on".
All works perfectly, but my question is.
How "dodgy" is it to have port 23 open on my router, or is there a better way?
