Here is a ps1 script that takes the interface name, the ip to route and the ipmask and routes an ip trough a interface. It can be a vpn or a normal network card. It utilizes route.exe for route adding and .net for NIC IP determination. It also deletes a route.

param(
[string] $InterfaceName = “Grupo Visabeira”,
[string] $IP2Route = “192.168.3.138″,
[string] $IPMask = “255.255.255.255″,
[SWITCH] $Delete)
#$delete = $true
IF ($Delete){
$local:res = route delete $IP2Route
IF ($local:res -match ‘OK!’){”Route $IP2Route Deleted”}
ELSE{”Error Deleting $IP2Route: $local:res”}
}else{
[reflection.assembly]::LoadWithPartialName(”System.Net”) | Out-Null
$local:nic = [system.net.networkinformation.networkinterface]::GetAllNetworkInterfaces()|Where-Object {$_.name -eq $InterfaceName}
if ($local:nic.OperationalStatus -eq ‘Up’) {
$local:interfaceIP = ($local:nic.GetIPProperties().unicastaddresses|where {$_.ipv4Mask -ne ‘0.0.0.0′}).Address.IPAddressToString
if ($local:interfaceIP) {
$local:res = route add $IP2Route MASK $IPMask $interfaceIP
IF ($local:res -match ‘OK!’){”Interface [$InterfaceName] Connected and Route $IP2Route Added”}
ELSE{”Error Adding $IP2Route in Interface $InterfaceName : $local:err”}
}
}else{”Network Interface [$InterfaceName] Not Connected”}
}

Any idea how to automatically execute that script after a connection has been established to the VPN?
