Question

Hi,

I have  a Windows Server 2008 configured as VPN Server , i have defined static ip address for some client due to some need , because our AX Server need to connect to client for some data pushing and we need static ip address for client ,

but the issue is some time client didn't get the ip address which is defined in its properties , but a different one , and if we disconnect and connect again its get the right ip address , sometime we need to do the disconnect many time to get the correct ip address ....

is something i am missing to get the specific ip address for vpn user ??

Hi Balal,

First, we could check the events of DHCP Client service to see if it could help to analyze the problem.

Then, we could check the settings of clients again.

If its configuration is right and it still doesn’t work, we may try to use Dial-in properties.

  • Open Active Directory Users and Computers.
  • Double click the user and choose Dial-in tab.
  • Choose Assign Static IP Addresses and configure it.
  • Open Network Policies of VPN in NPS server.
  • On Overview tab, do not choose Ignore user account dial-in properties.

Here is the guide for configuring:

we are not using DHCP.

we are not using NPS.

users are local instead of AD

Hi Balal,

We could also assign static IP addresses for clients in dial-in properties if they are not domain users. The procedure is described in the article.

Besides, which method you took to assign addresses for remote clients?

Hi Balal

I suppose we could use Network Monitor to analyze the problem.

Here are the steps.

1. Set the client to use PPTP as VPN protocol. 

2. Install Network Monitor on client and start a new capture.

3. Connect VPN on client.

4. Then we could analyze the process to find the problem.

Here is the guide for Network Monitor:

Here is the reference for PPTP:
