Here is an example of how to bridge a wireless device with parprouted:
On the host:
sudo sh -c "echo 1 > /proc/sys/net/ipv4/ip_forward"
sudo tunctl -t tap0
sudo ip link set tap0 up
sudo ip addr add 192.168.1.25/24 dev tap0
sudo route add -host 192.168.1.30 dev tap0
sudo parprouted wlan0 tap0
On the guest:
auto eth0
iface eth0 inet static
address 192.168.1.30
netmask 255.255.255.0
network 192.168.1.0
broadcast 192.168.1.255
gateway 192.168.1.25
But parprouted only supports IPv4.
In the Wikipedia article about Neighbor Discovery Protocol (NDP) there is the following citation:
"Neighbor Discovery Proxy (ND Proxy) (RFC 4389) provides a service similar to IPv4 Proxy ARP and allows bridging multiple network segments within a single subnet prefix when bridging cannot be done at the link layer."
I have a wireless card with this configuration (my MAC address is random):
$ ip address show dev enp3s0
2: wlan0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_pie state UP group default qlen 1000
link/ether 3a:25:eb:5b:a9:dc brd ff:ff:ff:ff:ff:ff permaddr 88:d7:f6:41:c3:e5

I want to "bridge" the wireless card (wlan0) to a TAP virtual interface and set in the guest the address of the TAP as the default gateway, just like the example above. And of course, assigning a new IPv6 to the TAP interface.
How can I bridge the wireless device (which cannot be bridged directly with brctl tool) to a TAP virtual interface and enable IPv6 communication between bridge/tap and the wifi interface?
Remembering, my IPv6 addresses are configured using SLAAC in the router.
