Both machines are in local network and connected to the WEB via it.
They are inaccessible from the outer World. If I want to ssh to my
system from the outside of the building I have to order  'static IP'
for additional $5 per m. So, David, thank you for the tip but I'm
doubt whether I actually need to block udp 517. Am I right here?
