Hello all you Geek....

For the security purpose, let me know what you think. let say that I have a server with 2 nic cards in it. I want to connect the first nic to the wireless router so I can recieve the router ip address, the 2nd nic I would like to connect it to a hub so it can able to assigned an ip address from the server to the rest of workstations which connect to the hub. The server is running windows 2003.

Thanks

Having two nics does not make your server more secure. It does force you to route workstation traffic thru the server which slows the server down.

Both interfaces on the server should have statically assigned ip addresses. Then in turn you authorize your servers dhcp server to hand out ip addresses to the workstations on that lan cards subnet.

Do you know how to do this?

Thank you for replying...

The way that i was thinking is that, the router ip address is 192.168.1.x, I want the server dhcp to assign a different ip address. So all the workstation using the internal ipaddress

Thanks

That would be a given if you wanted to route thru the server.

Have you worked with servers before? Routing thru the server is a more advanced network topic than just using the router as the single point of internet access.

sure. do you plan on running AD?

disable dhcp server on the router
assign a static ip to the nic attached to the router in the same subnet as the router like 192.168.1.10 for example
assign a static ip to the lan nic like 192.168.0.1
enable and authorize your server dhcp server on the lan nic with scope 192.168.0.10-254 [if you want that large of a scope]

or

Enable RRAS between the two networks [nics]

This is it in a nutshell

You should have the server up on all the service pacs and hot fixes as well as having dns server configured properly [this is a basic you will already know] before you do the above

Post an ipconfig /all from a workstation for review.

Did you put the isp dns servers in the dns forwarders tab?

It would appear that for some reason you are listing two different subnets for both dns and gateway.

You don't list the router attached to server nic subnet in the dhcp server.

You will have to tell me which subnet is the lan and which is the wan for the server.

Yes, one is from the server and other from the router...
