PowerCLI for allowed IP List

Doing something similar to this post.... PowerCLI Script for Firewall allowed IP's

I am trying to add a list of IP's to the vsphere client firewall service. 

Here's what i have:

$cluster = mycluster

$ip1 = "1.2.3.4/24"

$ip2 = "5.6.7.8/24"

foreach($esx in (Get-Cluster -Name $cluster | Get-VMHost)){

        $esxcli = Get-EsxCli -VMHost $esx

        $esxcli.network.firewall.ruleset.set($false, $true, "vSphereClient")

        $esxcli.network.firewall.ruleset.allowedip.add("$ip1", "vSphereClient")

        $esxcli.network.firewall.ruleset.allowedip.add("$ip1", "vSphereClient")

        $esxcli.network.firewall.refresh() }

When i flip the $false and $true like it has in the linked post, i get errors saying it is already set to 'all'.  When i leave it the way I have it above, it "half-works" and changes the setting to "Only allow connections from the following networks:"  like it should.... but it never inputs the ip addresses.... therefore, vsphere loses connection to the host, yada yada....

Thanks for your time.
