Thank you
i’m going to assume that you have: - both clients and the server on different subnets/VLANs (this should be obvious) - a router acting as DHCPv6 relay agent DHCPv6 CANNOT give a default gateway to clients, that can only be done using Router Advertisements (RA). RA can only be configured on the router attached to the client’s subnet (look at the NDP RA command line structure on whatever OS you are using). Most implementations I’ve seen will make the current router interface a candidate for default gateway unless you configured the "lifetime" to 0 Another thing you might want to verify/confirm: your windows clients now have /128 addresses. that has implications for on-subnet reachability. hope that helps ./shalom
