DSL connection
From Grokdoc
Setting up an xDSL can be a hair-pulling endeavour. It's not intuitive and even people certified in networking forget about the "default" IP to find a router. First, you want the info from eth0 (and eth1 if a second card is installed).
A Windows "ipconfig" command may print out the following:
Ethernet adapter Local Area Connection:
Connection-specific DNS Suffix . :
Description . . . . . . . . . . . : Intel 21140-Based PCI Fast Ethernet
Adapter (Generic)
Physical Address. . . . . . . . . : 00-40-05-31-31-F1
Dhcp Enabled. . . . . . . . . . . : No

Ethernet adapter Local Area Connection 2:
Connection-specific DNS Suffix . :
Description . . . . . . . . . . . : NETGEAR FA310TX Fast Ethernet Adapter (NGRPCI)
Physical Address. . . . . . . . . : 00-A0-CC-31-31-5E

Default Gateway . . . . . . . . . :
Someone needs to add a bit of info about connections, methods and local networking here.
Note that the second adapter ("Local Area Connection 2") has no IP address. It needs one. Set it to 169.254.179.25 with a subnet mask of 255.255.0.0 (169.254.179.25/16). It needs this address so that it can "find" the router. Basically, the set-up looks like this:
INTERNET < --- > EXT IP (ROUTER) INT IP -->> NIC 2 <-- NIC1 -> LAN
The router needs to have 2 IP's: one on the Internet and one for you. The "169.254.x.x" is a qualified IANA IPand happens to be te default on routers. It's a default because this is what Microsoft goes looking for.
Anything in the range 169.254.179.x is OK, so either use YaST, SaX, some other GUI method, or from a command shell, enter:
ifconfig eth1 169.254.179.20 netmask 255.255.255.0 <enter>
Since NICs (Network Interface Connectors) are cheap (available for as little as US$6 at the time of writing [June 2004]) and most boards come with one pre-installed, having two NICs is a good idea. While you probably have just one computer, the second NIC will allow you to easily create a network and share your resources with another machine, either yours or a guest's.
