So, the destination is not responding with SYN,ACK when the connection passes our router. But as I said it is reachable from my home, and this is confusing.
In such situations, I use HPING in the following manner: hping3 -n -T -S -p 443 yy.yy.yy.yy
Breakdown: -n - do not do DNS resolution -T - traceroute mode -S - send SYN packet (you should see flags=SA in the output for a reachable machine) -p - the destination port - 443 in this case
You can a -t ## to start off with a larger tty than the default 0.
