Message-ID: <19981109062136809-18a15359@high-voltage.com> Mime-Version: 1.0 Content-Type: text/plain; charset=us-ascii Sender: owner-freebsd-questions@FreeBSD.ORG Precedence: bulk X-Loop: FreeBSD.ORG I've got a PPP dialup that gives me a fixed IP. Beautiful - everything works. I'd like to add a cable modem into the mix, but since that provides a dynamic IP, I'm going to keep the PPP dialup active. The behavior I'd -like- is for client requests to come in on the static 56k (later ISDN) line, with data going out through the cable modem. Is this possible, or even automatic if I make my route "lo0 ed0 tun0" (loopback, then ether, then user mode PPP)? Will remote clients accept responses coming back from a different IP address than the one from which a session was requested? A seperate, related question - assuming I get the above working: If the cable modem bandwidth is ever saturated, will outbound data automatically shift to the ISDN unit, or would I need to configure routing software to accomplish this? If I choose an ISDN router instead of a serial ISDN TA, would it be necessary to place the router on a seperate ethernet card to accomplish this, or is FreeBSD smarter than I'm giving it credit for?
