2.3.2. Connecting to the Internet or External Network

How are you currently connecting to the Internet, today?

If you are connected through an external broadband modem or router, you probably will be connected via an Ethernet network interface card or NIC. In any case, a similar card must be in your IPCop PC. If you are connected via an internal analog modem, ISDN modem, or ADSL USB modem, this must be moved to the IPCop PC. If you are connected via an external dial up modem, you will have to connect it to your IPCop PC.

This hardware will be used for your RED network interface.

Write down some key parameters from your current interface.

2.3.2.1. Checking Your DHCP Host Name

If you don't know if your ISP requires a host name, or you don't know what it is, check the paperwork that came with your ISP's installation kit or call their support center for help. If that fails, enter:

$ ifconfig -a

on a *nix platform, and look at your eth0 IP address. On Windows 95, 98, ME, etc. the command is

C:\>winipcfg

entered from the command prompt. On Windows NT, 2000, XP, Windows 7, etc. the command is

C:\>ipconfig /all

In any case, write down your IP address and then issue an

$ nslookup nnn.nnn.nnn.nnn

command, where nnn.nnn.nnn.nnn is your IP address. If you get a response, write down the full host name you receive. The first part may be your DHCP hostname, the last part may be used to configure IPCop's DHCP server.
