# Role Native Wireguard
|
|
Manages wireguard on a client.
|
|
|
|
## Create Client Keys
|
|
```bash
|
|
wg_private_key="$(wg genkey)"
|
|
wg_public_key="$(echo "$wg_private_key" | wg pubkey)"
|
|
echo "PrivateKey: $wg_private_key"
|
|
echo "PublicKey: $wg_public_key"
|
|
echo "PresharedKey: $(wg genpsk)"
|
|
```
|
|
|
|
## Debug
|
|
|
|
### 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
|
|
```
|
|
|
