Thanks bro, is recommended to have just one IP for stacking and another one for doing other personal stuff (for security issues)?
You can do what you want but why? If you´re afraid of coinstealing you can set up a internal network with a DMZ
I will check DMZ in a future if I consider it necessary. I am not afraid about EMB but about Tezos, for which I pretend stake a higher amount when it launches (in 2020 or so XD).
Thanks @Lumobox, you are a real cryptofriend
