direct access client cannot access resources by ip address

    Domanda

  • Hi,

    I have setup my laptop as a DA client, everything works fine but i have noticed that each time that i try to access a website in my LAN by IP address it fails, if i replace the IP by a DNS name it works, same for RDP if launch mstsc with an IP it fails, if i replace with DNS name it works.

    Why can't i work with IP addresses from my DA client?

    You cannot use IPV4 addresses because the IPSEC tunnels rely on IPv6. If you try to reach ressources by IPv4 addresses, your DirectAccess clients will try to access ressources according to IPv4 routing informations available. Your client does not have routing informations for your IPv4 subnet. It won't pass throught the tunnels. If you need to access ressources by IP, you must use IPv6 and have a look at ISATAP.
