Question

DNS in W2K3 Domain with Watchguard Firewall

Asked by: supportoranges

Cisco 1700 Router with local side address of 192.168.1.1
Watchgard X500 Firewall with a public address pointing to Cisco as its gateway
   .  configured in drop in mode
   .  trusted interface cabled to switch to which LANs hosts are connected
      trusted interface configured to 192.168.1.1
Poweredge Server  192.168.1.35
      runs DNS forwarding requests to external isp if it cannot resolve
Client PC
     gateway configured to 192.168.1.1 which pushes traffic through the Firebox
     dns1 <valiid DNS of ISP.  dns2 is 192.168.1.1

my concern is that dns2 never gets to the Poweredge Server.  shouldn't i just make the dns of the client pc equal to the IP of the Poweredge Server?  (server is domain controller running AD in W2K3SP1 world)

The second DNS setting is only used, whenever the first DNS Server is not reachable. As long as the first DNS is working, the second never will be used.

As your Poweredge server uses forwarders, your clients should only point to your poweredge server.
