Public/New-IPPoolFixedRange.ps1
#Required by functions #New-P2PTunnelNAT <# .Description Create a New Fixed Range IP Pool .Parameter IPPoolName Specify a Unique name for the IP Pool .Parameter ExternalCIDR Specify the external CIDR range for the IPPool .Parameter InternalCIDR Specify the internal CIDR range for the IPPool .Example $Params = @{ IPPoolName = "CompanyIPSECPool" ExternalCIDR = "10.155.127.0/24" InternalCIDR = "192.168.1.0/24" } New-IPPoolFixedRange @params .Example New-SSHSession -computername 192.168.0.1 $Params = @{ IPPoolName = "CompanyIPSECPool" ExternalCIDR = "10.155.127.0/24" InternalCIDR = "192.168.1.0/24" } $command = New-IPPoolFixedRange @params $result = Invoke-SSHCommand -Command $command -SessionId 0 $result.output This example generates an SSH session and invokes the output of this function against that session. .Example New-SSHSession -computername 192.168.0.1 New-SSHSession -computername 192.168.1.1 $Params = @{ IPPoolName = "CompanyIPSECPool" ExternalCIDR = "10.155.127.0/24" InternalCIDR = "192.168.1.0/24" } $command = New-IPPoolFixedRange @params $sessions = Get-SSHSession foreach ($session in $sessions) { Write-Output "Invoking Command against $session.host" $result = Invoke-SSHCommand -Command $command -SessionId $session.sessionID $result.output } This example generates multiple SSH sessions and invokes the output of this function against all active sessions. .Notes Source NAT (IP Pool) and Destination NAT (Virtual IP) \ Destination NAT changes the destination address of packets passing through the Router. It also offers the option to perform the port translation in the TCP/UDP headers. Destination NAT mainly used to redirect incoming packets with an external address or port destination to an internal IP address or port inside the network. \ Source NAT is most commonly used for translating private IP address to a public routable address to communicate with the host. Source NAT changes the source address of the packets that pass through the Router. A NAT pool is a set of addresses that are designed as a replacement for client IP addresses. .Link https://github.com/TheTaylorLee/AdminToolbox/tree/master/docs #> Function New-IPPoolFixedRange { [CmdletBinding()] Param ( [Parameter(Mandatory = $true)]$IPPoolName, [Parameter(Mandatory = $true)] [ValidateScript( { if ($_ -match '^[0-9]{1,3}[.]{1}[0-9]{1,3}[.]{1}[0-9]{1,3}[.]{1}[0-9]{1,3}[/]{1}[0-9]{1,2}$') { $true } else { throw "$_ is an invalid pattern.
