I am trying to setup a FreeBSD 13.0 router for IPv6 and IPv4.  The IPv4 =
addresses are all statically assigned.  IPv6 should come from a prefix =
delegation from "ISP" and then sub-deligated to local LANs and hosts.  I =
have tried numerous approaches from various postings but still have two =
issues:

1.  DHCP for IPv6 doesn't seem to really work.  There are several =
packages available, but comments indicate issues with them.  In any =
case, none of them seem to be viable in the router setup, but only in =
the lower hosts.

2.  The entries in /etc/resolv.conf never seem to work for both IPv4 and =
IPv6.  The name servers for both are different.  There is one for each =
protocol and which ever one is listed first in resolv.conf will return a =
not-found response for any request using the other protocol. =20

Any ideas on how to make this work?
