Yesterday, my firewall (Outpost) kept popping up with IP addresses warning me of proto41 connections. At first I blocked them. They kept coming up and were all sequential address numbers. (126.96.36.199,172,174 ect. the other was 188.8.131.52.) I did a reverse IP on them and it said they were Microsoft ISP's located in my region the midwest. After blocking several times I moved on to blocking and adding to blocked list. They still popped up so I blocked the proto41 connection type. I looked up what it wasand honestly not completly understanding just don't like the sound of tunneling. This mornig I turned on my computer and McAfee advised of a new network connection. Now I cannot access my router through the address I have used. I ran ipconfig/all and my default gateway and dns have changed. When I put that in my browser it takes me to my modems config/setup. Any help in atleast explaining what might have happened or how to get back to where I was?
