Anyone managed to get BTBroadband's Voyager 100 modem working under
I've got Mandrake 10 Community running and have downloaded the French
drivers and done a ./configure, make, make install. Basically I've
followed the instructions given at
http://eciadsl.flashtux.org/index.php?lang=en but have had no luck.

Thank you for your recent enquiry on broadband from Southern Electric.
We currently have broadband from Southern Electric available in some
areas of Winchester.

And you still have to be in Winchester!

We (that is, work) use Smoothwall Express (the GPL version - 
there's a commercialware version as well). Fairly simple 
setup in our case but it's worked well for us. FWIW they 
seem to have got to significant pains to support all the 
wyrd and wonderful USB ADSL / cable modems that are out 
there (with what success, I'm not sure).

I'd add the proviso that you'd need to be really sure of 
what you're doing to go down this route. Certainly doing it 
yourself will give you valuable expertise, but a live 
firewall isn't the best place to learn - there's too much 
risk if you make a mistake.

Are you aware of this? http://www.schneier.com/pptp.html

Do you actually believe that:

(a) Southern Electric is plugged directly into a/some first tier global
backbone provider(s) (Level 3, UUNet, one or two others) rather than,
say, BT


(b) the sum of their port speeds with that/those provider(s) is equal to
or greater than the sum (i.e. 1:1 contention ratio) of the port speeds
offered to all of their customers? (e.g. A mere 10,000 customers with
500Kb/s connections would require cross-connects totalling a
gob-smacking 5Gb/s.)
