Doesn't always help.  The problem is usually a difference of potential
between the phone line and the power line under lightning fault conditions.

I have a power distribution center with filtering and protection that
powers all my computers and my DSL modem (scrounged at a local school).  It
has phone line protection that worked fine with dialup but I can't use it
with DSL.

That can happen, but it's less likely with an external modem.  I've lost
several modems to lightning but the only time I had a motherboard damaged
was when I was using an internal modem.
