  • No DNS for VPN users?

    We have a DLINK DFL-1000 firewall which is setup for PPTP VPN access. Thus, a user logs onto our network via a WinXP-reated VPN connection. The firewall assigns an IP to the clients as they connect.

    I've found that DNS does not work for these users and thus have had to manually setup our DNS server (192.64.10.10) in the DNS settings for the VPN client.

    Is there any way that I can use the Domain Controller to give out the DHCP & DNS settings to VPN clients coming in thru the firewall?

    Windows 2003 Server and WinXP clients.

    Hi,

    I would recommed you to use Win2k3, configure RRAS to act as a VPN using PPTP or L2TP protocols and let the RRAS act as a DHCP Relay Agent in the same time. Then your VPN clients once they are connected the DHCP Relay Agent will provide the IP settings that you have specified.

    Hope it helps!

      I know what you're saying, but things just start getting complicated now because I would have to create a VPN pass thru on the firewall so that the VPN goes to the RAS server, which I don't think is possible using this old hardware firewall.

      So I take it there is no solution using the existing setup?

        Nothing is impossible. What is your Infrastructure Setup?

          Hardware firewall acting as the gateway to the internet. Domain Controller, SQL Server, Web Server and Terminal Server all Windows 2003 Server.

          The firewall controls all satellite office VPNs as well as remote user VPNs (WindowsXP). Router has in-built dual-modems (one for internet one for satellite offices) and is a Cisco 1700.

            Can you not set these options via the firewall??

            Here's the manual for it. I haven't had the tie to skim through it but if i get some time i'll try.

              Alright,

              COnfigure the RRAS as a VPN Server and let the RRAS to provide IPs to clients by using the DHCP Relay Agent!

              Is that what you wnat to do ?

              Thanks,
