Message-ID: MIME-Version: 1.0 Content-Type: TEXT/PLAIN; charset=US-ASCII Sender: owner-freebsd-isp@FreeBSD.ORG Precedence: bulk X-Loop: FreeBSD.org We had to put in a cisco 1605 router (with 2 ethernet ports) between our net and our isp supplying our backbone connection. The "ethernet", which is only a crossed 10BT cable between the two routers, does it need real ip adresses? +-----------+ +-----------+ +----+ ----- --our net---+ E0 E1 +------+ E0 S0 |-----+ | \ 3C's | 1605 | | 100x | | +---- +-----------+ ^ +-----------+ +----+ | Can I use 192.168.1.0-adresses here? Or even unnumbered ip? Our uplink isp wants us to subnet one of our C's in a /30, is this really nessecary?
