So the isp modem has an open port at listening for the isp management server. At least if what i read is right on this protocol and how in being hacked.
I think what confuses people is the article using the term router.. people think of their home router as the only router.. but the isp modem is also a router if forwards L3 traffic from one L3 interface to another L3 interface.
L3= network = IP Address in this case
They still can’t get past my firewall. They can’t get into my pc.
