Dual Stack Issues

[Doug Hardie]

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.  

Any ideas on how to make this work?
