I'll see what I end up doing with ADSL routers / modems
before
I go down this route - never used Linux before, just exploring the
possibilities. I have an old 120Mhz machine in a cupboard but
think it's a bit flaky. Thanks.
Most
ADSL modems present a USB port. Make sure that (a) your version
of
Linux supports USB and (b) that you can get Linux drivers for the
modem. Of course, with Ethernet presentation, you will need two NICS
to
go down the firewall route.
