Thanks. Honestly I'm not 100% sure I understand the difference between Serial and CIDR. I *think* Serial is the connection between my router(or firewall) and the ISPs router and CIDR is the publically addressable IP addresses. Is CIDR just the term to say for example, a class C is split up into several smaller ranges? Like 6 IPs instead of 255, or does it mean something else?
Thanks again for your help. I love learning new stuff. :) On Wed, Nov 3, 2010 at 11:18 AM, Raper, Jonathan - Eagle <[email protected]> wrote: > Jon, > > No problem.
