Information
ESXi runs a reverse proxy service called rhttpproxy that front ends internal services and application programming interfaces (APIs) over one HTTPS port by redirecting virtual paths to localhost ports.
This proxy implements a FIPS 140-2 validated OpenSSL cryptographic module that is in FIPS mode by default. This configuration must be validated and maintained to protect the traffic that rhttpproxy manages.
Solution
From an ESXi shell, run the following command:
# esxcli system security fips140 rhttpproxy set -e true
or
From a PowerCLI command prompt while connected to the ESXi host, run the following commands:
$esxcli = Get-EsxCli -v2
$arguments = $esxcli.system.security.fips140.rhttpproxy.set.CreateArgs()
$arguments.enable = $true
$esxcli.system.security.fips140.rhttpproxy.set.Invoke($arguments)
