  • DNS over OpenVPN

    hi all,
    I m asking your help about my problem because I cannot find the solution myself.
    I have my DNS server on site1 and over OpenVPN I want to use it to site2 on any pcs. DHCP on both site I use MS server.
    When I set the site1 dns settings on server or on pcs on site2 I can not access internet or joing the pcs into my domain on site1. I have check traffic with sniffer and I have find out that "srv" DNS records cannot pass through.
    I have try everything ,firewall, packet filter, Bypass everything, replace Untangle, set Untanglw DNS to forward the DNS traffic.......
    Same configuration I have install at site3 and it works ok.
    Can anyone find similar DNS problems with OpenVPN?

    And see if that helps you with the Joining of the domain.

    Your FW Module is that Default block or pass?

      nop, the post didnt help at all, I check the port 3 times but the guy there didnt know what he was doing!!! he use network wizard in XP to join pc into the domain, I dont think so.

      FW module was on pass mode but I had to remove FW on both sites and try again without any luck.
      Something blocks srv records traffic , I cannot find what that is.
      is been a week now working on that task but still nothing

        Do you export The DNS Servers over OpenVPN?

        Can site 2 verifiy with NSlookup that they dont have SRV record?
        Nslookup is a command-line tool that displays information you can use to diagnose Domain Name System (DNS) infrastructure.
        To use Nslookup to verify the SRV records, follow these steps:

        1. On your DNS, click Start, and then click Run.
        2. In the Open box, type cmd.
        3. Type nslookup, and then press ENTER.
        4. Type set type=all, and then press ENTER.
        5. Type _ldap._tcp.dc._msdcs.Domain_Name, where Domain_Name is the name of your domain, and then press ENTER.
        But you should still be able to modify the LMhost file on the host.

        Your DNS servers what gateway do they have?
        Maby they can't get the answer back over the VPN Tunnel.
