    Hi,

     

    Thank you for the update.

     

    Do you have specified a static pool of IP addresses for VPN clients? If you configure L2TP/IPSec  site to site VPN, please changed to PPTP VPN and see if it works? Do you have enabled NLB on the ISA server? If possible, I think you may refer to the following article to reconfigure the site to site VPN.

    Hi,

     

    Thank you for the post.

     

    Please check the VPN settings and configure the DHCP relay agent or specify a static pool of IP addresses for VPN clients.

     

    If the issue still remains, would you please tell us the following questions:

    1.      Is there an error message on the client machine when the connection fails?

    2.      Is it site to site VPN or remote VPN, and PPTP or L2TP?

     

    Regards,

    RASA,

    Is ISA trying to connect to another ISA Server or a 3rd party VPN device such as Cisco or Sonicwall?

    Did it ever work? Is this a new error?

    The more information you can give us the better equipped we will be to help you.
