I have created a powershell script to create a VPN, connect to add, add the routes for it.
The only issue I am having is that my gateway for that VPN is not known upfront, so users need to add it with a parameter.
This isn't so clean, so I would like to retrieve the gateway from the VPN connection in PowerShell. Is there any way to this?
I am connecting to my VPN like this "rasphone.exe -d $name".
How can I obtain the gateway for this VPN so I can route certain IP's through the VPN?
I have found a working approach:
First I need to get the IP configuration for the VPN connection
$ipConfiguration = Get-NetIPConfiguration | where { $_.InterfaceAlias -eq $name } | Select-Object -First 1
Than I can add routes for this VPN like this:
ROUTE.EXE ADD $ip MASK $mask $ipConfiguration.IPv4Address.IPAddress if $ipConfiguration.interFaceIndex;
The IP address is not the actual gateway, but in the docs I have read that the closed gateway is taken. This works perfectly!

How to reset an IP address on every reboot. Is it possible with powershell to write a script such that the IP address is resetted to dynamic IP address every time a user tries to log in?
You sure can!
First you would need to find your network adapter via WMI. The one you want to refresh IP adress.
$ethernet = Get-WmiObject –Class Win32_NetworkAdapterConfiguration | Where-Object { $_.IpEnabled }
Then you would want to release DHCP ip adress using ReleaseDHCPLease() method. Like so:
$ethernet.ReleaseDHCPLease()
Then you want to renew DHCP ip adress using RenewDHCPLease() method. Like so:
$ethernet.RenewDHCPLease()
I am very new in socket programming.
I installed windows server 2008 and dns server on vmware.Now I want to change dns server settings via client with powershell.
What should I do?
So, I'm really not sure what are you trying to achieve, but since you mentioned Powershell. This is the code to set the DNS server settings for the Network Adapter. You have to run this in powershell.
$ifindex = (Get-NetAdapter -Name adaptername).ifIndex
Set-DnsClientServerAddress -InterfaceIndex $ifindex -ServerAddresses "dns address"
Might be I misunderstood you?
In my home network , I have to set IP address and DNS server. In Office network that settings to be removed .
Daily i am doing this activity manually. Though powershell automate so many things ,I am not finding any cmdlet for this in Windows 7.
I am doing the procedure manually . Is there any way to solve this using powershell? Even if batch file is there for it , I can use it
Here is a script that I use for that.
$wmi = Get-WmiObject win32_networkadapterconfiguration -filter "ipenabled = 'true'"
if($wmi.count -eq 1)
{
$wmi.EnableStatic("10.0.0.2", "255.255.255.0")
$wmi.SetGateways("10.0.0.1", 1)
$wmi.SetDNSServerSearchOrder(#("10.0.0.3","10.0.0.4"))
}
An an even better option for most situation (especially home networks) is to use DHCP. If you have a wireless router, It should have that option.
Isn't PowerShell a bit of overkill?
You can use simple NETSH command from command line.
To check config:
netsh interface ip show config
To turn on DHCP:
netsh interface ip set address name="Local Area Connection" source=dhcp
To setup static address:
netsh interface ip set address name="Local Area Connection" source=static addr=192.168.0.100 mask=255.255.255.0 gateway=192.168.0.1
I am using Windows XP Sp3. We are having both wired network and wireless network.
Both will have different IP address range .
Is there any way to find which IP address/Gateway is used to communicate?
i.e. We are having permission to wired network IP range to rdp to our lab machines. But with wireless connection we can't.
Often people forget that and asking me.
If the wireless network is active channel , then it should either try to connect through wired network or it should intimate them. How to achieve this using powershell?
You can get the same information route print shows like this:
Get-WmiObject -Class Win32_IP4RouteTable | select Destination, Mask, NextHop, Metric1
If your network address is 10.0.0.0 you can get the NextHop IP like this:
Get-WmiObject -Class Win32_IP4RouteTable | ? {$_.Destination -eq "10.0.0.0"} | select NextHop
As I understand you should manually add routes to lab machines for wired interface. And you could detemine current route settings with command:
route print
running from windows console (cmd )
Guess this links could be also helpfull to you:

I am currently using Powershell to get me the list of all the IP Address of my machine. When I am not using my vpn connection ( when I am at work) I get the IP Address of my machine correct. but When I am at home and I am using my VPN connection, I get another IP Address which is being provided by the client. I would like to get the second IP Address provided to me by the VPN client.
I am currently using this query
(gwmi -query "Select IPAddress From Win32_NetworkAdapterConfiguration = True").IpAddress
However like I have said before this query does not give me the IP address provided by the VPN client .
Please suggest..
Thanks and Regards

try this:
[System.Net.Dns]::GetHostEntry($a).addresslist
Return al IP4 and IP6.
Cisco VPN not always show to client the IP of vpn connection.
