    You can refer to [Redundancy](./redundancy.md) for more information.
-   
-   It is also worth noting that the `--beacon-nodes` flag can also be used for redundancy of beacon nodes. For example, let's say you have a beacon node and a validator client running on the same host, and a second beacon node on another server as a backup. In this case, you can use `lighthouse vc --beacon-nodes http://localhost:5052, http://local_IP:5052` on the validator client.
+
+2. If the beacon node and validator clients are on different servers *and different networks*, it is necessary to perform port forwarding of the SSH port (e.g., the default port 22) on the router, and also allow firewall on the SSH port. The connection can be established via port forwarding on the router.
+
+
+
+      In the validator client, use the flag `--beacon-nodes` to point to the beacon node. However, since the beacon node and the validator client are on different networks, the IP address to use is the public IP address of the beacon node, i.e., `lighthouse vc --beacon-nodes http://public_IP:5052`. You can get the public IP address of the beacon node by running the command ` dig +short myip.opendns.com @resolver1.opendns.com` on the server running the beacon node.
+
+      Additionally, port forwarding of port 5052 on the router connected to the beacon node is required for the vc to connect to the bn. To do port forwarding, refer to [how to open ports](./advanced_networking.md#how-to-open-ports).
+
+
+      If you have firewall setup, e.g., `ufw`, you will need to allow connections to port 5052 (assuming that the default port is used). Since the beacon node HTTP/HTTPS API is public-facing (i.e., the 5052 port is now exposed to the internet due to port forwarding), we strongly recommend users to apply IP-address filtering to the BN/VC connection from malicious actors. This can be done using the command:
+      
+      ```
+      sudo ufw allow from vc_IP_address proto tcp to any port 5052
+      ```
+      where `vc_IP_address` is the public IP address of the validator client. The command will only allow connections to the beacon node from the validator client IP address to prevent malicious attacks on the beacon node over the internet.
+
+
+It is also worth noting that the `--beacon-nodes` flag can also be used for redundancy of beacon nodes. For example, let's say you have a beacon node and a validator client running on the same host, and a second beacon node on another server as a backup.

+The reason why Lighthouse logs in UTC is due to the dependency on an upstream library that is [yet to be resolved](https://github.com/sigp/lighthouse/issues/3130). Alternatively, using the flag `disable-log-timestamp` in combination with systemd will suppress the UTC timestamps and print the logs in local timestamps.

 Beacon node and Lighthouse Validator client.
 
-> The Beacon Node must be run with the `--gui` flag set. 
+To enable the HTTP API for the beacon node, utilize the `--gui` CLI flag. This action ensures that the HTTP API can be accessed by other software on the same machine.
 
-If you run Siren in the browser (by entering `localhost` in the browser), you will need to allow CORS in the HTTP API. This can be done by adding the flag `--http-allow-origin "*"` for both beacon node and validator client. If you would like to access Siren beyond the local computer, we recommend using an SSH tunnel. This requires a tunnel for 3 ports: `80` (assuming the port is unchanged as per the [installation guide](./ui-installation.md#docker-recommended), `5052` (for beacon node) and `5062` (for validator client). You can use the command below to perform SSH tunneling:
-```bash
-ssh -N -L 80:127.0.0.1:80 -L 5052:127.0.0.1:5052 -L 5062:127.0.0.1:5062 username@local_ip

+> The Beacon Node must be run with the `--gui` flag set.
 
-where `username` is the username of the server and `local_ip` is the local IP address of the server. Note that with the `-N` option in an SSH session, you will not be able to execute commands in the CLI to avoid confusion with ordinary shell sessions. The connection will appear to be "hung" upon a successful connection, but that is normal. Once you have successfully connected to the server via SSH tunneling, you should be able to access Siren by entering `localhost` in a web browser. 
+If you require accessibility from another machine within the network, configure the `--http-address` to match the local LAN IP of the system running the Beacon Node and Validator Client.
 
-You can also access Siren using the app downloaded in the [Siren release page](https://github.com/sigp/siren/releases). To access Siren beyond the local computer, you can use SSH tunneling for ports `5052` and `5062` using the command:

-```  
+In a similar manner, the validator client requires activation of the `--http` flag, along with the optional consideration of configuring the `--http-address` flag. If `--http-address` flag is set on the Validator Client, then the `--unencrypted-http-transport` flag is required as well. These settings will ensure compatibility with Siren's connectivity requirements.

 # Frequently Asked Questions
 
 ## 1. Are there any requirements to run Siren?
-Yes, Siren requires Lighthouse v3.5.1 or higher to function properly. These releases can be found on the [releases](https://github.com/sigp/lighthouse/releases) page of the Lighthouse repository.
+Yes, the most current Siren version requires Lighthouse v4.3.0 or higher to function properly. These releases can be found on the [releases](https://github.com/sigp/lighthouse/releases) page of the Lighthouse repository.

 ## 3. How do I fix the Node Network Errors?
 If you receive a red notification with a BEACON or VALIDATOR NODE NETWORK ERROR you can refer to the lighthouse ui configuration and [`connecting to clients section`](./ui-configuration.md#connecting-to-the-clients).
 
-## 4. How do I change my Beacon or Validator address after logging in?
-Once you have successfully arrived to the main dashboard, use the sidebar to access the settings view. In the top right hand corner there is a `Configuration` action button that will redirect you back to the configuration screen where you can make appropriate changes.
+## 4. How do I connect Siren to Lighthouse from a different computer on the same network?
+The most effective approach to enable access for a local network computer to Lighthouse's HTTP API ports is by configuring the `--http-address` to match the local LAN IP of the system running the beacon node and validator client. For instance, if the said node operates at `192.168.0.200`, this IP can be specified using the `--http-address` parameter as `--http-address 192.168.0.200`.
+Subsequently, by designating the host as `192.168.0.200`, you can seamlessly connect Siren to this specific beacon node and validator client pair from any computer situated within the same network.
 
-## 5. Why doesn't my validator balance graph show any data?
-If your graph is not showing data, it usually means your validator node is still caching data. The application must wait at least 3 epochs before it can render any graphical visualizations. This could take up to 20min.
+## 5. How can I use Siren to monitor my validators remotely when I am not at home?
+
+There are two primary methods to access your Beacon Node and Validator Client remotely: setting up a VPN or utilizing SSH-reverse tunneling.
+
+Most contemporary home routers provide options for VPN access in various ways. A VPN permits a remote computer to establish a connection with internal computers within a home network. With a VPN configuration in place, connecting to the VPN enables you to treat your computer as if it is part of your local home network. The connection process involves following the setup steps for connecting via another machine on the same network on the Siren configuration page and [`connecting to clients section`](./ui-configuration.md#connecting-to-the-clients).
+
+In the absence of a VPN, an alternative approach involves utilizing an SSH tunnel. To achieve this, you need remote SSH access to the computer hosting the Beacon Node and Validator Client pair (which necessitates a port forward in your router). In this context, while it is not obligatory to set a `--http-address` flag on the Beacon Node and Validator Client, you can configure an SSH tunnel to the local ports on the node and establish a connection through the tunnel. For instructions on setting up an SSH tunnel, refer to [`Connecting Siren via SSH tunnel`](./ui-faqs.md#6-how-do-i-connect-siren-to-lighthouse-via-a-ssh-tunnel) for detailed guidance.
+
+## 6. How do I connect Siren to Lighthouse via a ssh tunnel?
+If you would like to access Siren beyond the local network (i.e across the internet), we recommend using an SSH tunnel. This requires a tunnel for 3 ports: `80` (assuming the port is unchanged as per the [installation guide](./ui-installation.md#docker-recommended), `5052` (for beacon node) and `5062` (for validator client). You can use the command below to perform SSH tunneling:
+
+```bash
+
+ssh -N -L 80:127.0.0.1:80 -L 5052:127.0.0.1:5052 -L 5062:127.0.0.1:5062 username@local_ip
+
+```
+
+
+Where `username` is the username of the server and `local_ip` is the local IP address of the server. Note that with the `-N` option in an SSH session, you will not be able to execute commands in the CLI to avoid confusion with ordinary shell sessions. The connection will appear to be "hung" upon a successful connection, but that is normal. Once you have successfully connected to the server via SSH tunneling, you should be able to access Siren by entering `localhost` in a web browser.
 
-## 4. Does Siren support reverse proxy or DNS named addresses?
+
+You can also access Siren using the app downloaded in the [Siren release page](https://github.com/sigp/siren/releases). To access Siren beyond the local computer, you can use SSH tunneling for ports `5052` and `5062` using the command:

+```
+
+## 7. Does Siren support reverse proxy or DNS named addresses?
 Yes, if you need to access your beacon or validator from an address such as `https://merp-server:9909/eth2-vc` you should follow the following steps for configuration:
