I have successfully installed Wireguard on Debian Buster. Now I wanted to configure IPv6 afterwards. I have done that. But the settings inside the [Peer]-Section of wg0.conf do not seem to be persistent.

systemctl stop wg-quick@wg0.service
nano /etc/wireguard/wg0.conf

Result:

[Peer]
PublicKey = xxxxx
AllowedIPs = 10.200.200.2/32, xxx:xxxx:xx:xxx:100::2/72

After saving and restarting the service systemctl start wg-quick@wg0.service the wg0.conf looks fine.

When I restart the VM or the Service again, all my additional settings are lost.

[Peer]
PublicKey = xxxxx
AllowedIPs = 10.200.200.2/32

Any idea?

Thats how my wg0.conf should look like

[Interface]
Address = 10.200.200.1/24
Address = xxxx:xxx:xx:xxx::1/72
DNS = 10.200.200.1
SaveConfig = true
PostUp = iptables -A FORWARD -i wg0 -j ACCEPT; iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE; ip6tables -A FORWARD -i wg0 -j ACCEPT; ip6tables -t nat -A POSTROU$
PostDown = iptables -D FORWARD -i wg0 -j ACCEPT; iptables -t nat -D POSTROUTING -o eth0 -j MASQUERADE; ip6tables -D FORWARD -i wg0 -j ACCEPT; ip6tables -t nat -D POSTR$
ListenPort = 51820
PrivateKey = xxx

[Peer]
PublicKey = xxx
AllowedIPs = 10.200.200.2/32, xxx:xxxx:xx:xxx:100::2/72

[Peer]
PublicKey = xxx
AllowedIPs = 10.200.200.3/32, xxx:xxxx:xx:xxx:100::3/72

[Peer]
PublicKey = xxx
AllowedIPs = 10.200.200.4/32, xxx:xxxx:xx:xxx:100::4/72

Solved the issue. The magic trick: always stop the Interface with wg-quick down wg0 before editing the wg0.conf File. systemctl stop wg-quick@wg0.service will override the wg0.conf File after the next start.
