+## Debug 
+
+### RTNETLINK answers: Permission denied
+When ```systemctl restart wg-quick@wg0.service``` returns __RTNETLINK answers: Permission denied__, modify _/etc/sysctl.conf_:
+
+```bash
+net.ipv6.conf.all.disable_ipv6 = 0
+net.ipv6.conf.default.disable_ipv6 = 0
+net.ipv6.conf.lo.disable_ipv6 = 0
+```
+
+Afterwards reload: 
+```bash
+sysctl -p
+systemctl restart wg-quick@wg0.service
+```
+
+
+### SSH
+
+When the SSH connection over wireguard is buggy try: 
+
+```bash
+ip li set mtu 1400 dev eth0
+ip li set mtu 1400 dev wlo1
+```
+
+This can be connected to the [MTU](https://www.imperva.com/learn/application-security/what-is-mtu-mss/)
