I have problems using DNS with FOrefront VPNH clients RRS feed

  • Question

  • Hi all

    I have an existing network set up like this:

    WAN <-> SonicWall <-> SWITCH <=> CLients and servers

    The servers are 1 AD Controller, 1 Exchange 2003 and 1 Terminal server.  All running WIndows 2003

    Now, I have installed some new DELL servers, running Windows 2008 R2 and HyperV.  THis to give some new functionallity....   

    I have allso installed a ForeFront server that will take the SonicWall's place soon.  But her's my problem:

    The ForeFront is added to the "new" domain.  Its set up as a VPN server and the IP is given by the "old" DHCP server.

    Problem is that the DNS is not responding for my VPN clients.  I have checked the settings on the IP for the clients and the DNS is set to the correct servers.  I can allso PING the DNS server.  So basically its like this:

    DNS Servers:
    ("AD1") and ("AD2")

    IP setting on the VPN client (given from the Forefront):
    IP: 172.16.10.X

    SO when I ping or from any client, I get responce, but if I ping AD1 or AD2 I get error

    Please help.  This is fustrating.
