This is in regards to my earlier post requesting kernel config information. I'll ask the same question but be a bit more specific this time. I am using a 166 mhz AMD K5 machine running freebsd 2.2.1 (soon to be 2.2-stable) with 32M ram. The machine has two NIC cards. One goes to an ascend pipeline 50, the other plugs into a hub of a 50-node Novell 4.1 network. I plan to provide the Novell network Internet access by proxying and using the freebsd machine as the default gateway. The Internet is connected via a 128kbps ISDN to the ascend router. My questions are as follows: 1) Are there any kernel configurations out there operating under similar conditions that I can compare with my own? 2) Am I better off configuring the ascend pipeline as a router or a bridge? Since it will only be receiving defaultroute IP from the freebsd gateway and will simply be forwarding those packets on to the ISP's router, do I really need the overhead of routing, or will bridging be more efficient? 3) Will user-ppp (tun0) allow me to set up a dial-up connection so that the freebsd machine can be called remotely and establish a ppp link, or will I need to use pppd (ppp0)? 4) Is it possible (feasible) for me to set up the modem as a throughput "supercharger" of sorts? In other words, after a certain throughput is reached, can I have the modem establish a dial-up ppp to the provider and provide another 28.8k on demand? I realize there are lots of questions here, but I would really appreciate any input I could get on this. Any similar experiences or links to information that pertains would be beneficial. Thank you very much, Mark Murdock fee@tetranet.net
