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? -- Doug
