Add multiple ip's to a windows firewall

PowerShell Help
1

I’m using the powershell script below to add multiple ip’s to a specific firewall rule in this case Rule SMB.

$name = Get-NetFirewallRule -DisplayName "Rule smb" 
$ips = @("192.168.1.150", "192.168.1.151")
foreach ($r in $name)
{
Set-NetFirewallRule -DisplayName $r.DisplayName -RemoteAddress $ips 
}

In this case I need to edit the script every time I want to use this. So I thought I’ll change the following:
instead of using

$ips = @("192.168.1.150", "192.168.1.151")

I want to use something like this which I tried

$ips = @("Read-Host "Enter your server ip's")

When I run the script i will prompt me to enter the ip addresses I tried to enter 192.168.1.150,192.168.1.151 to add both addresses to the rule. But the script fails. I get a error that the address is invalid. Addresses may be specified as ip addresses, ranges etc…
Also tried to enter “192.168.1.150, " 192.168.1.151” with this the script will fail to.

the scripts works when I enter only a single ip address so when I want to enter multiple addresses the script fails.
Can anyone help me with a solution?

Thanks a lot!

Read-Host returns a single string. If you typed two IP addresses separated by a comma, that would be the same as:

“1.2.3.4,1.2.3.5”

So it’s not a comma-separated list in a way that PowerShell can recognize and turn into an array. You’re going to need a more sophisticated prompting mechanism if that’s your goal. Me, I’d probably parameterize the script to accept a [string]$addresses parameter, declare it as mandatory, and then let PowerShell prompt. You’d enter one IP address per prompt, and hit Enter on an empty prompt to indicate you were done.
