15:46.hk S8 Oct. 27 2020 Good Day group, The own sg, vlan routing to ISP dhcpv6 ? - its ipv6 route told unable routed? - stub insight sg or modem.isp? The own rv ipv6 temp at ipconfig /all is AT wan, none PD possible to be set up... - wan v6 would be able to package exchanging to isp dhcpv6? - stub on this rv? The modem.isp only network to endpoint pc, - stub on modem possible ? - stub on vrrp v6 of isp ? - stub at ISP behind of the client 's rv, or sg or modem ? none of is then, no stub package would once tried , no longer possible to resent it as probably immediately dropped at the 1st transformation failed right afterward ?
