It worth noting at step 12.2.1 is not correct. If you write localhost explicitly, fishnet will throw a message saying it failed to parse the ip and force 127.0.0.1 which is unreachable. Better leave it empty so that the fishnet process gets local address at 0.0.0.0:7770 and receive any UDP traffic which arrives at 7770 port when the process is started as server. We were also able to confirm this behavior using nmap. However, it is maybe not safe and if you care about security than better to put server public ip address instead.

You can also simply connect to AWS EC2 console by using PuTTY to see the whole process click here.
