2 NIC configuration for Windows Server 2003

questions regarding addressing NIC #1 & NIC #2...i configure my modem to a different default gateway for added wireless security...configuration for Windows Server 2003 S.E....my network experience is above average in home routers, average in home WAP's, and above average in Windows XP O.S.

NIC #1
I.P. Adress = 10.20.0.100
S.N.M. = 255.255.255.0
D/G = 10.20.0.1
D.N.S. #1 = xx.xxx.x.xx
D.N.S. #2 = xx.xxx.xxx.xx

NIC #2
I.P. Adress = 10.20.0.1
S.N.M. = 255.255.255.0
D/G = Empty Field
D.N.S. #1 = Empty Field
D.N.S. #2 = Empty Field

if this is incorrect...help me fill in the blanks

i would assume that work stations would be assigned 10.20.0.100 and so forward...or would it be 10.20.0.101 and so forward...

A#1

 

If I remember correctly, your external and internal NICs need to be on different ranges: external = 10.20.1.1, internal = 10.20.0.1. Both subnets would be 255.255.255.0.

 

wouldn't that put my modem in a different data layer than the server and all the work stations...jumping the third ocelot would actually give me two different physical networks...at least i think...

 

k...here's the settings i used

NIC #1
I.P. Adress = 10.20.0.100
SNM = 255.255.255.0
D/G = 10.20.0.1
DNS#1 = xx.xxx.x.xx
DNS#2 = xx.xxx.xxx.xx

NIC #2
I.P. Adress = 10.20.0.101
SNM = 255.255.255.0
D/G = No Values
DNS#1 = No Values
DNS#2 = No Values

The server gives me the assignable address scope of 10.20.0.10 Through 10-20.0.254

So far physical layout

NIC#1 to Modem
NIC#2 to Auto Sensing 16 port switch

At this point I do have an active internet connection to the server. I haven't added any work stations yet.

 

I believe the entire purpose of having two NICs is to have an internal network and external network. The server is connected to the outside world, and provides the link between your internal network and the external network. Your server is the DHCP for all of your internal workstations. Don't you want to have a separation?

 

@ kegobeer…i see your point…maybe i should explain further…my set up…DSL modem/router set to bridge mode/(not assigning DHCP addresses)…so 10.20.0.1 isn’t really my public I.P….it is just the default gateway to the modem/router…even left in the default gateway of 192.168.1.1…still not my public I.P….i just change the default gateway for added wireless security…let me tell you i’ve read several articles on google…about DHCP/RAS servers and as usual some contradict others…i haven’t put the server online yet…but do have an active PPPoE connection to it…just want to make sure when i start adding workstations everything will be o.k.
