I found my system at various stages of updates within the 11 release = series and tidied it up to v12 as it became an official release. I use FreeBSD on a Zotac mini PC as a firewall, router, caching DNS = server and for other things. It has 2 nics - one public and the other on my LAN. It does NAT for IPv4 = and I=E2=80=99m using the PF firewall with great results. What I am NOT able to make work is IPV6. My ISP is Comcast and they = support full IPv6 over DHCP and this worked on BSD 8 and 9 using the = instructions here: https://blog.crashed.org/setting-up-freebsd-with-comcast-ipv6/ = <https://blog.crashed.org/setting-up-freebsd-with-comcast-ipv6/>; I need to get the IPv6 address from Comcast on device re1 with the first = 64 bits and then provide the route for the LAN clients and the address = space with bits 65+. What is particularly MADDENING about the FreeBSD documentation pages is = that they do not indicate which VERSION is being discussed. Therefore, I = do not know which may apply to my version. *** I have tried this method: = https://subatomicsolutions.org/8-freebsd/13-ipv4-and-ipv6-address-via-dhcp= -on-a-dual-stack-network = <https://subatomicsolutions.org/8-freebsd/13-ipv4-and-ipv6-address-via-dhc= p-on-a-dual-stack-network> It does not work because dhclient -6 is broken *** This appears to be a dead-end as well: = https://forums.freebsd.org/threads/how-to-properly-set-up-an-ipv6-gateway.= 39431/ = <https://forums.freebsd.org/threads/how-to-properly-set-up-an-ipv6-gateway= .39431/> *** I have tried this, but it does not update my interfaces: = https://forums.xfinity.com/t5/Internet-Archive/WORKS-FreeBSD-Router-with-c= omcast-IPV6-and-default-gateway/td-p/3041558 = <https://forums.xfinity.com/t5/Internet-Archive/WORKS-FreeBSD-Router-with-= comcast-IPV6-and-default-gateway/td-p/3041558> *** Using rtsol: rtadvd: *** So, what should I be using? dhcp6c - appears broken dual-dhclient - appears broken rtadvd - not well documented *** FTR, I=E2=80=99ve been doing Unix of some sort or another since 1990. = SCO, AIX, Linux, OS X, etc. FreeBSD was supposed to be my island of = stability given the fork problem in Linux. That I=E2=80=99ve spent 20 = hours with Google trying to find out how to set up an interface is = maddening.
