I had this issue where I was only able to connect to websites like google.com and ibm.com when the mtu was set at 1500, but if I tried to connect to anything else, it would just show a blank page. When the mtu was lowered to 1499, it started working. I am curious as to why this works and if having the mtu set at 1499 could cause problems in the future? I actually don't know much about this, I just heard about it and am looking for a good explanation.
When I get an explanation of why the MTU was dropped by only 1 byte, I will update my question with the explanation.
