I presume you got a single IP address.  You need to configure your DSL
router to use that address on its out side instead of its previous
DHCP setting.

Not sure how you were set up, but normally the in side of your DSL
router is connected to a hub or switch, to which all your inside
machines connect, and your LAN will continue to be served non-routable
IP addresses by DHCP from your router, usually from the 192.168.1.0
block.

Not sure what you mean.  If the DSL router has no firewalling
capabilities, you should put one between the DSL router and the
internal network.  I have a simple DSL modem (no router function) so I
have an old cast-off Linux box with three network cards (at least two
required) that serves as my NAT/firewall/router.  One card goes to the
DSL modem, one goes to my LAN hub, and one goes to my DMZ, a single
machine running my mail and web servers.

Your router may assume an inside address of 192.168.1.1 or
192.168.1.254.  That will be the "gateway" address for the rest of
your machines.

If your ISP didn't specify one or more DNS servers, you can probably
use the same ones that were configured by DHCP.
