Re: SonicWALL/cable Internet/dynamic IP configuration help needed by John

I've been using the SonicWALL for five years with a DSL modem and static IP
addresses. I'm new to dynamic IPs. Perhaps the Wizard ran when I first set
up the DSL five years ago, but I'd forgotten it was there.
When I said the SonicWALL "needs to have the IP address range specified,"
what I really should have said is that it didn't work until I specified the
range of IP addresses. I know one doesn't need the Wizard, but I don't know
enough about this stuff to have done it correctly until I discovered the
Wizard.
SonicWALL charges an arm and a leg for extended warranties, etc. I'm sure
it's worth it, but this box is so old, I'm not even sure they'd offer it to
me. The SonicWALL/10 is nowhere to be found on their Web site.
Anyway, on to Christmas... and thanks again for your posts.
