There are two networks: Your local LAN The ISPs network The router's job is to sit on both networks and to pass traffic betwen them as required. The LAN will probably have the address 192.168.1.0, and machines on that LAN will replace that zero with some number 1-254. So in all likelyhood your router will be 192.168.1.1, and your computer will be 192.168.1.2 The ISPs network will give your router an address, let's say 10.1.1.45 When your computer wants to send a packet to a machine that is not on the 192.168.1.0 network it sends it to the address that it has been told is the "default gateway". That would be 192.168.1.1 in this case. You could (I do) set all these numbers up by editing /etc/hosts and using "route" to add the router as the default gateway. But there is an easier way. Just configure the router to get it's external address by DHCP, and act as a DHCP server to the LAN. IIUC, that's the usual factory settings. Then configure your computer to be a DHCP client. IIUC, that's easy using MCC. Now all those numbers are handled for you and you can ignore them. The system just works. Why do I do things differently? 1. I have a static IP address, so the external address is not going to change. 2. I have a network printer, and sometimes other computers on the LAN. It's useful to know their addresses are not going to change. It is possible to set that up with DHCP, but it's just as easy to not bother with it and do it by hand. ------- Aron, On an ethernet network every ethernet card has an address that looks like 34:54:65:76:98:ba. That's the "ethernet address". You should ignore it unless you are setting up static addresses in the DHCP server, (see 2 above.) It has absolutely no effect on the TCP/IP networking, (that you need to know about.) MCC in no way translates it. I can go into more detail if you want, but this probably isn't the right thread. -- Richard Urwin
