<dd>The public IP address of your Wireguard server that the client will connect to. Click on
<strong>Suggest</strong> button to auto detect the public IP address of your server.</dd>
<dt>2. DNS Servers</dt>
<dd>The DNS servers will be set to client config.</dd>
<dt>3. MTU</dt>
<dd>The MTU will be set to server and client config. By default it is <code>1420</code>. You might want
to adjust the MTU size if your connection (e.g PPPoE, 3G, satellite network, etc) has a low MTU.</dd>
<dd>Leave blank to omit this setting in the configs.</dd>
<dt>4. Persistent Keepalive</dt>
<dd>By default, WireGuard peers remain silent while they do not need to communicate,
so peers located behind a NAT and/or firewall may be unreachable from other peers
until they reach out to other peers themselves. Adding <code>PersistentKeepalive</code>
can ensure that the connection remains open.</dd>
<dd>Leave blank to omit this setting in the Client config.</dd>
<dt>5. Forward Mark</dt>
<dd>Set an <code>fwmark</code> on all packets going out of WireGuard's UDP socket. Default value: <code>0xca6c</code></dd>
<dt>6. Wireguard Config File Path</dt>
<dd>The path of your Wireguard server config file. Please make sure the parent directory
exists and is writable.</dd>
