I have a new Dell 1800 Server with SBS 2003 Windows Standard edition. It has 2 nic cards that I will be installing. It will replace an old win2k server with one Nic card. I plan to use the basic firewal with RWW, VPN to remote and mobile users, and Exchange Server.
Currently I connect to the internet via a Cisco 1721 router manitained by my ISP SBCIS. I have 13 ip addresses from my ISP but they are not used. They are not passed into our LAN. The default gateway IP is 22.214.171.124
I am a novice about networking. I am confused about whether I need 2 ip address assignments or 3 ip address assignments. Should the new server ip address be different than the 2 nic cards? Should it be on the same subnet as
the internal nic card?
