Hello, Using FreeBSD 8.0-RELEASE, and am trying variations in /etc/rc.conf in an attempt to enable IPv6 on ONLY one of the systems two interfaces. Specifically, em0 should be enabled IPv4 DHCP, and bge0 should be enabled IPv6 only. From the KAME link below, and the files /etc/network.subr and /etc/defaults/rc.conf, am reading that "ipv6_network_interface" should work; however the following still results in em0 obtaining IPv6 addresses: http://www.kame.net/~suz/freebsd-ipv6-config-guide.txt ifconfig_em0="DHCP" ipv6_enable="YES" ipv6_network_interface="bge0" ipv6_network_interfaces="bge0" In another attempt (see link below), it looks like "ifconfig_em0" may support a "NOIPV6" param, but in practice it doesn't seem to work for me: http://lists.freebsd.org/pipermail/freebsd-rc/2007-May/001106.html ifconfig_em0="DHCP NOIPV6" ipv6_enable="YES" #ipv6_network_interface="bge0" #ipv6_network_interfaces="bge0" Am hopeful that someone might point out how I could enable this configuration. Thanks in advance! -Brett
