Cisco 827 Config

Oh yeah, I was going to post my Cisco 827 config that I use with Qwest's new 1.5M (uncapped) DSL and ArosNet. Here you go. Keep in mind that this is just my configuration. There are many different possibilities that can be just for your setup. There are lots of really good resources out on Cisco's site for lots of different scenarios. I found this document to be quite helpful. The other guides from that section might be helpful, to you, too. Numbers and names have been changed to <bla> to protect the innocent.
There is one thing that I may change for dialer0 that will affect other stuff:
ip address negotiated
to
ip unnumbered Ethernet 0
I would have a hard time doing "overloaded" natting (a.k.a port natting, or masquerading) but would allow me to just use one IP address instead of having the dialer have another IP address. But for now, I'll keep it how it is.
I also have the preliminaries for running a DHCP server on the router, but haven't turned it on yet.
