Correct IP address for DNS Setup
Posted on 2008-02-10
Been on this site for a few weeks and have already learned more than the network classes I took three years ago. Unfortuanly, the other job took precedence, but I'm geting back into it.
What IP address should I set in my TCP/IP for the Server? The Static assigned by my ISP or as I thought and read something I decide on, like 192.168.1.100?
My static IP is 69.73.xx.xx and it routes thru port 2 of a cisco router (not sure of the model, it's mounted to the wall). Gateway IP 69.73.xx.xxx. I have a Kingston Ether Pro hub attached to Port 2 with the server and one client plugged into the hub.
I've tried both ways and the only way I get to the internet is by assiging my static IP. When I set to the 192.168...., I get a notice about the gateway not being on the same subnet and no access.
WIth the static IP, I get all the indications DNS is working properly. (NSLOOKUP comes back to my Static IP and my domain name, etc.) Then I setup DHCP with a scope of 192.168.1.1 - 20, authorize and all appears fine. When I test a client computer, it's like the DHCP request turns left at the gateway and finds a IP address outside instead of finding the DHCP from the Server. I've tried the clinet with and without a gateway setting, plus with and without the DNS setting point to the Server (static IP)
Am I getting confused on internal and external domains? I'm trying to setup a Server (AD, DNS and DHCP) for a 5 XP machine network.
Network Background on the building: The network: 10 XP machines running as a workgroup. I installed a Server 2003 R2 and need 5 of the 10 computers on a secure seperate network. Matrix Fiber Optic with 24 port cisco with gateway IP 69.73.xx.xxx (not sure model number, ISP manages it and ID plate is against the wall). Ports 8-24 are for VoIP. Ports 1-6 are static IP's (69.73.xx.xxx - 69.73.xx.xx) 1 is the WAN and Port 6 is the LAN. Port 6 connected to a 3 Com Cable/DSL. Ports 2, 3, 4, and 5 are Static IP's. Port 7 is dead (according to ISP Tech Support). I attached a Kingston Ether Pro Switch to cisco port 2 and the sever to the Kingston switch. Clinet plugged into the Kingston switch as well. ISP DNS's are 69.1.xx.xx and 69.1.xx.xx.
Appreciate any help for a NOIB DNS'er
