Powershell Script Modification

# get ip addresses that are not already in firewall rule.
$w = $g | where {$_.Name.Length -gt 1 -and  !($arRemote -contains $_.Name + '/255.255.255.255')} 

# add IPs to firewall rule
$w| %{$ar.remoteaddresses += ',' + $_.Name} 

Open in new window


I have the above code as part of a scrip that automatically grabs and logs IPs into a Block Rule on a Windows Server.   This script is deployed across multiple servers, but one client is having a problem where their internal IPs are being blocked by some users with drives mapped via VPN.

I've unsuccessfully attempted to add to this, so maybe an Expert can help -- I'd like to tack on an exception to the criteria to skip all IPs on the internal subnet (in this case, 192.168.125.0/24 ).  Any help is appreciated, thanks!

Hard to say without knowing what the variables contain.
Try comparing the IP with this regex (I'll just use $ip to represent the IP) in a Where-Object scriptblock.
$ip -notmatch "192\.168\.125\.((25[0-5])|(2[0-4][0-9])|(1[0-9][0-9])|(0?[0-9]?[0-9])|0?0?([0-9]))$"

Since we know the value is an IP, a more simple approach can be used:
# get ip addresses that are not already in firewall rule.
$w = $g | where {$_.Name.Length -gt 1
 -and  !($arRemote -contains $_.Name + '/255.255.255.255')
 -and $_.Name -notlike '192.168.125.*'} 

# add IPs to firewall rule
$w| %{$ar.remoteaddresses += ',' + $_.Name}
