Question : Cisco 827 router with ADSL connection setup and a Dynamic IP (Magma in Canada with DynDNS)

Hi,

I have a Magma account (Canadian DSL ISP) using a dynamic IP and currently using DynDNS. The current setup is a Speedstream 5660 in bridge mode going into a Linksys WRV54G router, everything is working great with the router handling the PPPOE and Dyndns connection. I would like to replace the Speedstream with the Cisco 827. I have the Cisco hooked up with a rollover console with 12.1 loaded , I cannot figure out how to get the mysterious 10.10.10.1 interface up via the ethernet connection. Can some one please walk me through getting this thing talking to the outside world. Once I get it up I'll get a book and learn it properly but I need a push in the right direction. I definitely figure this is worth 500 for a quality answer as the cisco pages are really good at giving reams and reams of commands and they don't even tell you how to get the non-console interface up.

Thank you for any help

*A simple DHCP set-up.

ip dhcp pool DHCP
network 192.168.100.0 255.255.255.0
dns-server 195.64.68.28 195.64.65.25
default-router 192.168.100.254
lease 0 0 15

This DNS set-up enables the assignment of the IP range 192.168.100.0 (with a netmask of 255.255.255.0). Some options like the assignment of the DNS servers of the ISP You can extract while you get your ip address assigned from the ISP.
