When You Need This

Stratos runs on the same PC as your simulator by default — no setup required. You only need this guide if your sim and Stratos are on different machines on the same home network, for example:
  • A dedicated simulator PC with Stratos on a laptop or streaming box
  • A cockpit rig where only the visuals run on the sim PC
  • Running Stratos on a Mac while the sim runs on Windows
If both apps live on the same PC, close this page — you don’t need to touch anything.
Both machines must be on the same local network (same Wi-Fi or same router). Stratos can’t reach your sim over the internet.

​
Step 1 — Find the Sim PC’s IP Address

On the PC running the simulator, open Command Prompt and run: 
ipconfig
Look for the IPv4 Address line — it’ll look something like 192.168.1.5. Write it down.

​
Step 2 — Let Stratos In

​
MSFS 2020, MSFS 2024, P3D, FSX

These sims read a small settings file called SimConnect.xml when they start up. On most installs the file already exists — you just need to change one line in it. Open the file at the path below for your sim: 
%LOCALAPPDATA%\Packages\Microsoft.Limitless_8wekyb3d8bbwe\LocalCache\SimConnect.xml
Paste the path into the File Explorer address bar — the %APPDATA% part expands automatically.
The file will have several <SimConnect.Comm> blocks — one for each connection type. The only one you need to touch is the first one, labelled Static IP4 port. It’ll look roughly like this: 
<SimConnect.Comm>
  <Descr>Static IP4 port</Descr>
  <Protocol>IPv4</Protocol>
  <Scope>global</Scope>
  <Port>500</Port>
  <MaxClients>64</MaxClients>
  <MaxRecvSize>41088</MaxRecvSize>
  <Address>0.0.0.0</Address>
</SimConnect.Comm>
The one line that matters is <Address>, usually sitting at the bottom of the block:
  • If it says <Address>127.0.0.1</Address> → change it to <Address>0.0.0.0</Address>
  • If the <Address> line is missing entirely → add <Address>0.0.0.0</Address> just before the closing </SimConnect.Comm> tag
0.0.0.0 lets the sim accept connections from other machines on your network. 127.0.0.1 means “same PC only”. While you’re there, note the <Port> value (usually 500) — you’ll need it in the next step. Leave every other block in the file alone. Save the file, then restart the simulator. That’s it on this side.
Some installs don’t ship a SimConnect.xml. If that’s you, create a new file at the path above and paste in this minimal template:
<?xml version="1.0" encoding="Windows-1252"?>
<SimBase.Document Type="SimConnect">
  <Descr>SimConnect Server Configuration</Descr>
  <Filename>SimConnect.xml</Filename>

  <SimConnect.Comm>
    <Descr>Static IP4 port</Descr>
    <Protocol>IPv4</Protocol>
    <Scope>global</Scope>
    <Port>500</Port>
    <MaxClients>64</MaxClients>
    <MaxRecvSize>41088</MaxRecvSize>
    <Address>0.0.0.0</Address>
  </SimConnect.Comm>

</SimBase.Document>
Save, then restart the sim.

​
X-Plane 11 / 12

Nothing to change. X-Plane already accepts remote connections out of the box on port 49000.

​
Step 3 — Point Stratos at the Sim PC

On the machine running Stratos, open Settings (gear icon in the sidebar) and scroll to Tracking Provider. Pick SimConnect or X-Plane to match your sim, then use the three controls highlighted below: Stratos Settings page with Custom IP / Port enabled, showing the toggle, IP address field, and port field
  1. Enable Custom IP / Port — flip the switch on. The IP and port inputs appear underneath.
  2. IP Address — enter the sim PC’s IPv4 address from Step 1 (e.g. 192.168.1.5).
  3. Port — 500 for SimConnect, 49000 for X-Plane.
Stratos reconnects automatically — no save button, no restart. The connection indicator in the top bar turns green once it’s through; it stays grey while disconnected.

​
Troubleshooting

Work through these in order:
  • Double-check the IP and port match exactly between the sim PC and Stratos
  • Make sure the sim is actually running and you’re in a flight (not sitting on the main menu — older sims only finish starting SimConnect once a flight is loaded)
  • Did you restart the simulator after saving SimConnect.xml? The file is only read when the sim starts
  • From the Stratos PC, open Command Prompt and run ping 192.168.1.5 (swap in your sim PC’s IP). No reply means the two PCs aren’t talking to each other on the network — that’s not a Stratos problem
Say yes, and make sure Private networks is ticked. If you clicked no by mistake, open Windows Defender Firewall → Allow an app through the firewall and tick the box next to your simulator.If the firewall prompt never showed up and things still aren’t working, try temporarily turning Windows Defender Firewall off to confirm it’s the culprit. If that fixes it, turn the firewall back on and add an inbound rule for the SimConnect port (500 by default).
Any free port works — Windows doesn’t restrict low numbers like some other systems do, which is why 500 is fine as a default. 5111 and 7421 are other commonly-seen choices. Whatever you put in <Port> in SimConnect.xml is the same number you enter in Stratos Settings.To check a port isn’t already taken on the sim PC, open Command Prompt and run netstat -ano | findstr :500 (swap in your port). If nothing shows up, the port is free.
  • Some Wi-Fi routers isolate clients from each other. Look in your router admin page for a “Client Isolation” or “AP Isolation” setting and turn it off
  • On the sim PC, make sure your Wi-Fi/Ethernet network is set to Private, not Public — Public networks block a lot of inbound traffic
  • Open X-Plane’s Settings → Network and confirm UDP data output is enabled on the port you entered in Stratos
  • Some third-party plugins grab port 49000 for themselves. Try setting a different port in X-Plane (e.g. 49010) and matching it in Stratos

​
Going Back to Local

Open Settings, toggle Custom IP / Port off, and Stratos will reconnect to your local sim automatically. You can leave the SimConnect.xml file in place — it only activates when Stratos asks for a remote connection.
