Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: 7bit Sender: owner-freebsd-isp@FreeBSD.ORG Precedence: bulk X-Loop: FreeBSD.org We have come across the following Probably not uncommon setup.

I want to replace the CISCOXXXX with a FreeBSD box, but I'm having difficulty in figuring out EXACTLY what is going on. Does anyone have experience with this sort of thing? (specifically and AT&T types out there that actually know wnat they are talking about , (as opposed to the guy I just spoke to).
