As of LCOS 10.30, the IKEv2 configuration payload supports the specification of a source for prefix delegation.
In LANconfig, the configuration is located under .
- Address pool
- Receive prefix from
- With this parameter you can assign addresses to the VPN clients from the prefix that the router retrieved from the WAN interface via DHCPv6 prefix delegation. Select the desired WAN interface here. For example, if the provider assigned the prefix "2001:db8::/64", you can then set the parameter First address to the value "::1" in the Last address to "::9". In combination with the prefix "2001:db8::/64" as delegated by the provider, the clients receive addresses from the pool "2001:db8::1" to "2001:db8::9". If the provider prefix is greater than "/64", e.g.,"/48" or "/56", you must take subnetting for the logical network into account in the address.
Example:
- Assigned provider prefix: 2001:db8:abcd:aa::/56
- /64 as the prefix of the logical network (subnet ID 1): 2001:db8:abcd:aa01::/64
- First address: 0:0:0:0001::1
- Last address: 0:0:0:0001::9
