 This can increase connections/peers for your Qortal core node(s). We will try to make this scenario as simple as we can - as there are several variables. Choose the section below that fits your situation:
-===== Only One Node On Your Home Network With uPnP Enabled=====
+===== Single or Multiple nodes With uPnP Enabled=====
-**Option 1:** In this case, you only have ONE device that is acting as a blockchain node for Qortal AND your router has uPnP enabled. The default settings that your node will have comes with uPnP enabled - uPnP is a feature that most common routers provide by default. If you are unsure, ask your service provider. With uPnP enabled in the router, and only ONE node running on your home network, you do NOT need to configure anything further on this guide.
+**Option 1:** If you have only ONE node, and your router has **uPnP enabled**, you will not need to do anything, your single node will simply start obtaining incoming connections.
-**Option 2:** If your router does NOT offer uPNP, you will need to port forward AND disable the default uPnP in your settings.json:
+If you ARE going to use uPnP, **you can have MULTIPLE nodes** on the same LAN obtaining incoming connections **via uPnP** by simply modifying a SINGLE setting in **settings.json** for your SECOND node and HIGHER:
-) Stop the core:
+Simply edit **settings.json** for the nodes ASIDE FROM THE FIRST NODE, and change the listenPort for the subsequent nodes, below is an example for the second node on the LAN.
-<code>cd qortal && ./stop.sh</code>
-) Open your settings.json - this may be blank which indicates you have the default settings. You will then copy and paste the code below into the settings.json and click save:
+<code>
-<code>{
+{
-"uPnPEnabled": false,
+"listenPort": 22392
-"listenPort": 12392
 }
 </code>
-If you have settings already displayed, look for the uPnPEnabled section, if it exists, simply replace 'true' with 'false'. Then add the listenPort as shown above below uPnPEnabled section (or anywhere within the json settings as it doesn't have to be in a particular order - just be sure to add a comma after each listing, and DO NOT have a comma on the final listing.
+The above settings would be fine for your SECOND node, you do not need to do anything for the FIRST node, as it will run on the default port 12392. Any SUBSEQUENT node you will need to add **ONLY the above setting in settings.json**, with a **DIFFERENT port for each subequent node.** (**note - if you are on WINDOWS the settings.json you will modify is located in **%localappdata%\Qortal** folder. Do NOT remove any of the 'path' settings on Windows machines or your node will not work correctly!)
-) Login to your router and set the IP address of the node to "STATIC" or "Reserve IP Address" or whatever verbiage your router uses for this setting. This will prevent the node’s IP address from changing and affecting all of this configuration.
+**Option 2:** If your router does **NOT offer uPNP**, you will need to configure port forwarding (on your router).
-) In your router, configure port forwarding for this device:
+) Login to your router and set the IP address of the node to "STATIC" or "Reserve IP Address" or whatever verbiage your router uses for this setting. This will prevent the node’s IP address from changing and affecting all of this configuration.
+) In your router, configure port forwarding for this device:
 Inbound: 12392 (sometimes ‘inbound’ is titled ‘internal’)
 Outbound 12392 (sometimes ‘outbound’ is titled ‘external’)
 Protocol: TCP
-) Start your core:
-<code>cd qortal && ./start.sh</code>
+===== More Than One Node On Your Home Network (no uPnP)=====
-===== More Than One Node On Your Home Network =====
 If you have more than one node on your network, then you’ll want to:
+  * Set a static IP address for each node in the router.
+  * Configure port forwarding in the router for each node.
-  * Stop the core, then change the json settings on each node. **Please note: the json will have a unique entry on each of your nodes.**
+) Set the IP address of each node to STATIC. This will prevent the node’s IP address from changing and affecting all of this configuration.
-  * Disable uPnP in the router (if it is a feature in your router and already enabled).
-  * Configure port forwarding in the router for each node.
-  * Start the core on each node.
-) Stop the core on each node:
-<code>cd qortal && ./stop.sh</code>
-) Pay attention to which node you are going to number as Node 1, Node 2, and so on. Each node will have a DIFFERENT listenPort setting. Open your settings.json for Node 1 - this will be blank which indicates you have the default settings. You will then modify your json settings:
-**Node 1:**
-<code>{
-"uPnPEnabled": false,
-"listenPort": 12392
-}
-</code>
-What we are doing here, is adding a listen port entry for each node that correlates with the port forwarding in step 3 below. **Please note: the final entry does NOT have a comma after as we see with 12392 above. This is correct.** If you have settings already displayed, look for the uPnPEnabled section, if it exists, simply replace 'true' with 'false'. Then add the listenPort as shown above below uPnPEnabled section (or anywhere within the json settings as it doesn't have to be in a particular order - just be sure to add a comma after each listing, and DO NOT have a comma on the final listing.
-**Node 2:**
-<code>{
-"uPnPEnabled": false,
-"listenPort": 12393
-}
-</code>
-Note that Node 2 has a DIFFERENT listenPort number than Node 1, which will match the settings in your router for port forwarding as shown in step 3 below. If you have settings already displayed, look for the uPnPEnabled section, if it exists, simply replace 'true' with 'false'. Then add the listenPort as shown above below uPnPEnabled section (or anywhere within the json settings as it doesn't have to be in a particular order - just be sure to add a comma after each listing, and DO NOT have a comma on the final listing.
-**Node 3:**
-<code>{
-"uPnPEnabled": false,
-"listenPort": 12394
-}
-</code>
-If you have settings already displayed, look for the uPnPEnabled section, if it exists, simply replace 'true' with 'false'. Then add the listenPort as shown above below uPnPEnabled section (or anywhere within the json settings as it doesn't have to be in a particular order - just be sure to add a comma after each listing, and DO NOT have a comma on the final listing.
-**Node 4:**
-<code>{
-"uPnPEnabled": false,
-"listenPort": 12395
-}
-</code>
-If you have settings already displayed, look for the uPnPEnabled section, if it exists, simply replace 'true' with 'false'. Then add the listenPort as shown above below uPnPEnabled section (or anywhere within the json settings as it doesn't have to be in a particular order - just be sure to add a comma after each listing, and DO NOT have a comma on the final listing. And so on....
-) Login to your router and set the IP address of each node to STATIC. This will prevent the node’s IP address from changing and affecting all of this configuration.
 ) Set port forwarding for each node as shown in the following. Internal and external for each node will be unique and NOT match the other nodes:
-**Node 1:: Internal: 12392 External: 12392
+**Node 1** Internal: 12392 External: 12392
-**Node 2** Internal: 12393 External: 12393
+**Node 2** Internal: 12392 External: 12393
-**Node 3** Internal: 12394 External: 12394
+**Node 3** Internal: 12392 External: 12394
-**Node 4** Internal: 12395 External: 12395
+**Node 4** Internal: 12392 External: 12395
 etc.
-(Just change the last digit in each number.)
+(Just change the last digit in each number ONLY for the EXTERNAL port. You can leave everything else on defaults.)
-. Start the core on each node:
-<code>cd qortal && ./start.sh</code>
