Looking on a 5.4-STABLE system, the ipfw(8) manpage mentions 'me' but not 'me6'. Looking on the web, at http://www.freebsd.org/cgi/man.cgi?query=ipfw&apropos=0&sektion=8&manpath=FreeBSD+6.0-RELEASE+and+Ports&format=html I see 'me' and 'me6' options. So yes, it looks like it has been split. > Is this a change in the way the 6.0 kernel handles lo0 traffic in general? > > Is this a change in ssh forwarding? Or has there always been IPv6 traffic? IPv6 support has been around in FreeBSD for a long time. If this causes you pain (as it does for me), then I recommend you remove 'options INET6' from your kernel config and rebuild the kernel. Other things to look for are your hosts file, which may have ::1 localhost 127.0.0.1 localhost in which case you can swap them, or comment out the IPv6 ::1 one altogether (otherwise IPv6 is preferred over IPv4 when using localhost). Also, a lot of ports tend to build with IPV6 support unless you explicitly disable it. I think there's a setting you can put in /etc/make.conf but I can't remember offhand what it is.
