Mine is hooked up to a router/switch which is then connected to Bell's DSL box.
I've never had to use Sympatico's MSN/customer service pages for anything. I'm not sure why you'd have to now. To set up the DSL box itself through its web browser interface, that should be possible on an Amiga, it's not like it uses CSS or anything.
The Bell box did come with a CD that could work on Mac or Windows to configure the box, but you could do it through the box's web interface too. I didn't want to touch that setup CD with a 10ft pole since they usually install crappy customised IEs or some other garbage.
I would suggest buying a D-Link, Netgear, Belkin, etc. box to stick between the Bell box and your computer. Don't bother buying a combined DSL box/router/wireless device from Bell because they use horrible cut-down custom firmware. Just get a basic DSL box and you should be fine.
Oh, and don't expect anywhere near your top DSL speed from your Amiga. I'd get 150KB/s max on my 060 out of a connection that can easily do 300KB/s.
