Hello
currently the manual method for ipv6 does not support pointopoint
configurations
config
```
iface wg3 inet static
pre-up ip link add $IFACE type wireguard
pre-up wg setconf $IFACE /etc/wireguard/$IFACE.conf
post-down ip link del $IFACE
post-up wg set $IFACE fwmark 51097
address 172.21.68.1
netmask 255.255.255.255
pointopoint 172.21.68.9
iface wg3 inet6 static
address fe80::1:100/128
pointopoint fdc5:30f7:af0a:1000::1
```
resulting config
```
# ip -6 a s dev wg3
69: wg3: <POINTOPOINT,NOARP,UP,LOWER_UP> mtu 1420 state UNKNOWN qlen 1000
inet6 fe80::1:100/128 scope link
valid_lft forever preferred_lft forever
```
while this configuration is supported by ip without problems
(removing ipv6 config for wg3 in /etc/network/interfaces)
```
ip -6 addr add fe80::1:100 peer fdc5:30f7:af0a:1000::1 dev wg3
# ip -6 a s dev wg3
68: wg3: <POINTOPOINT,NOARP,UP,LOWER_UP> mtu 1420 state UNKNOWN qlen 1000
inet6 fe80::1:100 peer fdc5:30f7:af0a:1000::1/128 scope link
valid_lft forever preferred_lft forever
```
thanks!
