Function New-VIPHost { <# .Description Create a New Virtual IP for a single Host .Parameter VIPName Specify a Unique name for the Virtual IP Object .Parameter ExternalIP Specify the External IP used for the VIP. eg. The IP address used to access the host externally. .Parameter Interface Specify the Name of the External Interface from which the External IP will hit. .Parameter InternalIP Specify the Internal IP used for the VIP. eg. The IP address used to access the host internally. .Example $Params = @{ VIPName = "PatientPortal" ExternalIP = "57.65.98.23" Interface = "wan1" InternalIP = "192.168.8.15" } New-VIPHost @params .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 #> [CmdletBinding()] Param ( [Parameter(Mandatory = $true)]$VIPName, [Parameter(Mandatory = $true)][ValidatePattern('^[0-9]{1,3}[.]{1}[0-9]{1,3}[.]{1}[0-9]{1,3}[.]{1}[0-9]{1,3}$')]$ExternalIP, [Parameter(Mandatory = $true)]$Interface, [Parameter(Mandatory = $true)][ValidatePattern('^[0-9]{1,3}[.]{1}[0-9]{1,3}[.]{1}[0-9]{1,3}[.]{1}[0-9]{1,3}$')]$InternalIP, [Parameter(Mandatory = $true)]$port ) Write-Output " config firewall vip edit ""$VIPName"" set extip $ExternalIP set extintf ""$Interface"" set mappedip $InternalIP set portforward enable set extport $port set mappedport $port next end " } |
