DNS Forwarder "SBN via WinServerKB.com" <u32166[ at ]uwe> 5/19/2007 7:18:55 AM Hey guys in our network we have 3 servers 2 Windows domain servers (Main-172. 16.0.3 and Secondary-172.16.0.3) and 1 Linux-172.16.0.1 acting as a firewall. Our linux is installed with SQUID web proxy cache and all our clients browsers are using proxy server (172.16.0.1:80) default gateway:172.16.0.1 DNS:172.16.0.2,172.16.1.3. I have read about DNS forwarding and also want to implement it if possible in our network. I tried to set it up, so i choose our secondary server to be the forwarder and i configure our main server in the DNS properties to point to the secondary server as its forwarder. Now how do i configure our clients so that they can use the DNS forwarder? and did i setup the DNS forwarder correctly? -- Message posted via WinServerKB.com http://www.winserverkb.com/Uwe/Forums.aspx/windows-server-dns/200705/1

Clients use the Internal DNS server (set) which then (typically) forwards to a DNS Server (set) which can resolve OTHER names, e.g., the INTERNET. > and did i setup the DNS forwarder correctly? Maybe, but we don't know why you were forwarding to this secondary so maybe you did it wrong. Forwarding is about the DNS server being able to use a DIFFERENT DNS Server (i.e., the Forward is the additional DNS Server) to resolve names the original server does NOT know. > -- > Message posted via WinServerKB.com > http://www.winserverkb.com/Uwe/Forums.aspx/windows-server-dns/200705/1 >
