we have a manually assigned static /48 IPv6 prefix and for privacy reasons we need one stateful static /64 IPv6 subnet for incoming connections and one stateless random /64 IPv6 subnet for outgoing connections on the LAN device.
1st IPv6 prefix (incoming connections):
- Static /64
- DHCPv6 leases: :0:192:168:1:<last octet of IPv4 address>
- Preferred lifetime: 0
- Valid lifetime: forever
2nd IPv6 prefix: (outgoing connections)
- Random /64
- New subnet every 86400 seconds
- Preferred lifetime: 86700
- Valid lifetime: 172800
How can we configure this in OpenWRT?
Thanx for any hint
