DHCPV6 - "No Addresses Available"

[Henri]

Hallo,

ich habe ein Problem mit DHCPV6.
1783VAW 9.24RU4

Nativer Dualstack, ich habe im DHCPV6 Server ein Adresspool von "::1000" bis "::FFFF" mit "Receive Prefix" von "T-ONLINE" eingestellt.
Leider bekommt der Client keine IPV6 Adresse. Hat jemand eine Idee was ich hier falsch mache?

Danke und viele Grüße

Henri
