Got everything up and working now with the LAN block as virtual IP's.
FYI: For anyone changing the WAN adapter assignment, I found that I needed to go back through the CLI instead of the web browser to reassign all adapters before it would start routing traffic. Initially, I made the change on the adapter in Esxi, but nothing connected to the internet. Then, I created a completely new adapter and assigned it as the WAN interface in the web browser, but still, nothing happened. Eventually, I went through the CLI assignment for just the WAN and LAN, and then traffic started routing again. After that, I was able to reassign and reset the interfaces with the web browser.
