Ping says the Destination Host is unreachable for 10.10.10.27 with two hops in traceroutre.
Ping is working with 30 hops for 10.10.10.198 (easiest windows machine Buff).
Perhaps 10.10.10.27 is just having issues as I am now seeing that port 8080 is open for 10.10.10.198 (8080 and 7680 with -p- scan). However it is saying that the other 999 ports are filtered which is making me unsure still. I get two ports open for 10.10.10.191 with 998 filtered.
Perhaps you could check and see if you are seeing the same?
