Direct Access/VPN - Add server to Cluser creates some strange routes


  • Hello,

    Our DA/VPN servers have worked well for years (setup before I joined the company) but we recently decided to add two new Server 2012 R2 servers to the cluster. I went through the process to add the servers in Remote Access Management Console and the first server joined without and issue but when users connect their VPN, DNS doesnt work.

    So I checked the routing and a strange active route has been added during the server add i.e.  This IP doesnt relate to anything on our network.

    I tried removing the server from the cluster and sure enough the route was deleted and then added itself when I re-added it.

    I can see this IP in the DA sever GPO but I cant see this line when I edit the GPO and as I said I dont know what it is or what the probe address is as this isnt whats set in the console:


    I should point out that the old servers have no mention of in their routing table.

    the table:

    IPv4 Route Table
    Active Routes:
    Network Destination        Netmask          Gateway       Interface  Metric
         On-link    261
         On-link    306         On-link    306         On-link    261         On-link    261         On-link    306         On-link    266         On-link    266         On-link    266         On-link    306
           On-link    306
           On-link    306         On-link    306
           On-link    306
           On-link    261
           On-link    266
           On-link    306         On-link    306         On-link    261         On-link    266         On-link    306
    Persistent Routes:
      Network Address          Netmask  Gateway Address  Metric

    Any ideas what I can do???
