Sorry for the late response, I was out of the civilized world. Back on the question - unfortunately I'm not able to help with a definitive answer - most likely, it's the device which is responsible for blocking ports - the firewall or the router itself. My suggestion is to log into each suspicious machine and look for patterns like iptables, ACLs, etc.
I'm out of ideas how to check the IP that blocks certain packets to go at the destination.
