 > [!TIP]
 > You can modify the AllowedIPs in the `wiretap.conf` file any time after generating the config files, just reload the config file with `wg-quick down ./wiretap.conf && wg-quick up ./wiretap.conf` (or re-import them into the GUI) after making the change. No changes are needed on the Server to update them.
 
-> [!WARNING]
-> In the default configuration, with the Client listening for an initial Server connection, the Server will still also listen on port 51820 so that other Servers can attach to it later. There is currently no way to change this when running the `configure` command, but when running `wiretap serve` you can manually change this in the `wiretap_server.conf` file, or using the `WIRETAP_RELAY_INTERFACE_PORT` environment variable.

 Don't forget to disable or remove the tunnels when you're done (e.g., `sudo wg-quick down ./wiretap.conf && sudo wg-quick down ./wiretap_relay.conf`)
 
 ### Outbound Connections
-You can use the `--outbound` flag to configure the Client to Initiate the UDP connection to the Server. If you do, the `--endpoint` value will instead be used to tell the Client where to connect to the Server, and the `--port` value (explicit or implicit) will configure the Server's listening port.
+You can use the `--outbound-endpoint` flag to configure the Client to Initiate the UDP connection to the Server.

-In this case the Client will listen on 51820 in case other Servers need to be added using the default Inbound mode, but this can be changed via the `ListenPort` variable in the `wiretap_relay.conf` file if needed.
+In this case the Client will listen on 51820 in case other Servers need to be added using the default Inbound mode, but this can be changed by passing a value to the `--port` flag when running the `configure` command.
 
 ### Simple Mode
 While not recommended, you can add the `--simple` flag to configure Wiretap as a more traditional one-Client-and-one-Server VPN. Most of Wiretap's dynamic configuration features (any Wiretap commands you would run after establishing the initial connection) will be unavailable in this mode.
 
-> [!WARNING]
-> When starting the Server, you may need to also use the `--simple` flag. The Server currently does not support automatically detecting this configuration.

 ## Serve
 
 On the remote machine, upload the Wiretap binary and then run one of the commands from the output of `configure` to start Wiretap in Server mode:

 This command will modify the Client's E2EE configuration (`wiretap.conf`) to allow communication with the new Server, so you need to re-import it. For example, `sudo wg-quick down ./wiretap.conf && sudo wg-quick up ./wiretap.conf`. If you are attaching a new Server directly to the Client, the Relay config will also need to be refreshed in the same way.
 
-Now you can use any of the `serve` command options to start Wiretap on the new Server, just like you did after running the `config` command. It will then join the Wiretap network by connecting to the existing Server.
