Right, your basic problem is that your interfaces are now names
enp7s0
and
wlp6s0

not eth0 and wifi0 or whatever they used to be.

Fix them in /etc/network/interfaces, double check your iptables
rules are either using the new names or don't mention interfaces
at all, and you should be relatively happy.
