Use vm server ipv6 adress for internal network

Hello,

my vm server have a /64 ipv6 adress.

is it possible to distrubute (a part of) this network to an internal interface of the openwrt router.

Eg:

[VM eth0 (2001:db8:48:64::1/64)] -> [VM wg0 (2001:db8:48:64::2/64 ?)] --->
[OpenWrt wg0 (2001:db8:48:64::3/64 ?)] -> [OpenWrt eth0 (2001:db8:48:64:?::?/?)] ->
clients in the network get automaticly (RA/DHCPv6) a public ipv6.

Is this scenario with a /64 network possible?

thx.
