I've made a posting in Forum: ISA Server General - Installation - Caching DNS on ISA - today.
I can't get this Packetfilter DNS(TCP) running
The Caching DNS running fine with UDP Port:53 So I can use only my ISA and my Mail/Web/Time/Virus-Server to go Outside. The Servers with DNS have nomore need to go Outside because I use the DNS on ISA as Forwarder.
If i use DHCP on the internal network to hand out the ip address of my internal DNS server, and i have configured a DNS caching server on ISA, then which DNS server do i point my clietns to in order to resolve internal names and FQDN on the internet? The clients cant use the DNS server on ISA for name resolution on the internal network, wouldnt thsi be a problem?
I have always just configured my internal AD DNS server to use my ISP as a forwarder, and i never ran into a problem with name resolution on the internal network, or resolving names on the internet.
for your clients use your internal DNS-Servers - roll out with DHCP - ! Use only the Caching DNS on ISA as forwarder in the settings of your internal DNS-Servers. In the Caching DNS on ISA use your ISP-DNS as forwarder. So the Caching DNS on ISA is the only DNS-Server seeing the Outside !
i'm having the same problem with my 2003srv and isa timeing out after it's idle for several hours. the only way i've been able to fix it is reboot the isa box and all is well. Is there a way to avoid this or work around it? i also don't understand why it times out after being idle. all clients are secureNat clients and isa box is forwarder to isp for dns cacheing. please help
The Installation Write Up looks great but I am pretty new at this and I am unsure of what is meant in #2. "click on an address not bound to the internal interface of the ISA Server Firewall" I don't know what bound means in this. My Isa server has 1 internal IP on the LAN and 3 routable IP's on the WAN of which two are used for listeners for a web server and exchange server behind the ISA server. What IP do I select in this write up? Please help!
hi everyone Our Platform clients were connected to the internet using a router without Valid IP. I installed ISA server 2004 and now everybody in connected to the internet with webproxy though ISA server also without valid IP. Clients-ISA-Router-ISP-Internet I configured DNS for SecurNAT clients du to the tom's instruction . Both DNS and ISA are in the same Machine. DNS forwarder IP = Router Internal IP. Clients TCP/IP configuration : Dynamic IP From DHCP Default Gateway : ISA Internal IP Primary DNS : ISA Internal IP aslo add DNS server publishing rule in firewal policy. But I'm not able to access internet from clients with this configuration .
