I'm very interested in this as well, but I'm on 2.2.6. I picked up an 8-port 100Mbps (only!)-: hub for $100 from one of the web auction houses and want to connect my home boxes which have 100Mbps interfaces: x86 with FreeBSD and hopefully BeOS soon. But I've also got some old Suns and a laptop with 10Mbps interfaces which I can't afford to upgrade. Total of about 10 systems on a pair of 10Mbps minihubs right now. My plan is to split the net with the 100Mbps machines on the 100Mbps hub, and the 10Mbps boxes on the 10Mbps hub. I'll of course need to get traffic to flow across both. I was thinking I could put a 10Mbps and a 100Mbps card in my box which already dials my ISP 24x7 and let it move the packets to the right place. I'm looking for advice for how to get them from net to net. I've got a /240 subnet from my ISP. I'd really prefer not to subnet this into two /248s and lose two more addresses in the process. I'd also like to avoid dealing with gated If I can. Is there some simple bridging SW? I didn't find anything in the ports. If there is, what kind of HW do I need to support bridging at this speed? I don't need packet filtering and other firewall functions here, but if something like Drawbridge is the easiest thing to make work, I can do that. As long as it also will let me talk out the PPP interface to the world. Thanks a lot. To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
