How to assign 6.5 web console to use a /32 address?

What is necessary to tell ESXi to use a gatewayless /32 address for the web configurator?

I help run a small gaming community on a datacenter server. I have no access to the server's keyboard console. We are trying to switch to ESXi with the free license, but I am having huge problems trying to get this to work.

We have a single "normal" /30 IPv4 address plus an additional "gatewayless" /32 IPv4 address. In order to use the /32 address it needs to be routed through the /30's gateway.

,

Currently VMWare is configured to use the (/30) address for its web console. But this presents a problem for my VM's because you can't use the /32 without creating a separate WAN interface for the /30 address in order to route through its gateway.

And the instant I create a WAN interface for the /30 on my VM, I lose all communication because you can't share the /30 address with the VMWare web console and your own VM at the same time.

I am totally stumped as to how to proceed. As far as I can tell the only way forward is to twiddle around in the SSH console and create a static route for the /32, as described in this document:

Configuring static routes for vmkernel ports on an ESXi host (2001426) | VMware KB

,

But a second problem is how to move the web console over to the /32 address when I only have remote access, I don't have console access, and the datacenter host for the machine has no idea how to help with this.

If I can't switch the ESXi web console over from the /30 to the /32 in one single clean step, then I will be cut off from the remote access and fully locked out and unable to proceed, without having the datacenter host just "reset the configuration" and then we are stuck with using the /30 again.

After paying $300 for an incident support request I was told that unless console access is available, outside the web configurator or SSH, assigning the /32 address to the management console is not possible.
