i shall give u the card configuration by assumption ,u can change it as per ur requirement . for example ur : LAN IP is 10.0.0.1 -10.0.0.255your wan ip :61.11.83.2/24 & 61.11.83.1 as gateway ----Provided by ISP ....now the configuration will be as follows1.LAN NIC : IP :10.0.0.1Subnet Mask :255.0.0.0Gateway:----DONT PROVIDE ANY GATEWAY FOR LOCAL NIC. If u specify an gateway ip for local NIC ,then the packets will create a loop and internet may not work properly (however theres another way to resolve this )so leave the local nic gateway as Blank.2.WAN NIC IP:61.11.83.2Subnet Mask:255.255.255.0Gateway:61.11.83.1thts all done .... Configure your LAN pc's gateway as 10.0.0.1(ie:Local Nic's ip in win2k server).thats enjoy dude ,any issues buzz me ,Note ,the ip addresses provided here is only an example,it wud be different in your application/business ....Change/customise accordinlgy.
