Configuring VS to access LTM

I used the self-IP as the VS IP. When I started this 5 days ago, this option didn't work. I found a quirky fix. I created another self-IP on the same VLAN. I then tested the VS config using the original self-IP. It now works. I then deleted the new self-IP and tested. It still works. Yes, cleared my cache and used a different browser, too. Kind of weird, BUT it works.
