I was in a similar position to you not that long ago. I got my LAN all dual stack and was a happy camper. I wanted 100% IPv6 and never to see another RFC 1918 address on my network again. Unfortunately it's just not practical. My ReadyNAS doesn't talk v6. My mac doesn't appear to like v6 for the fi

What are your problems with using radvd? I have used it quite a bit on FreeBSD (6.1) without any hassle. It's even written quite nicely in my experience so working on patches for it should be quite do-able if there are features missing. He's saying that the router announcements don't contain a

You'd almost certainly be better off hacking up an extension to ipfw which lets you count a /24 in one rule. As in, the count rule would match on the subnet/netmask, have 256 32 (or 64 bit) integers allocated to record traffic in, and then do an O(1) operation using the last octet of the v4 addres

Hi all, I have been hitting some barrier with FreeBSD 7.1 network performance. I have written an application which contains two kernel threads that takes mbufs directly from a network interface and forwards to another network interface. This idea is to simulate different network environment. I
