I work from home a lot. My ISP used to never change IP addresses dynamically the first 3 years or so I was with them. Now they change it often (more than once a week). This creates a slower response time when I am at home, get a page, go to log in via ssh, and find out my ip has changed since we restrict our AWS environment via group policies. The times I have needed to do this are relatively few, but still its a problem if there is an emergency. Leave it to me to come up with a simple solution….
