# Proxy Setup Notes

Research notes for routing FIFA 23 traffic through OpenFUT Bridge.

---

## Goal

Intercept all FUT API calls from FIFA 23 so the Bridge can:
1. Log every request for reverse engineering
2. Route known endpoints to OpenFUT Core
3. Return placeholder responses for the rest

---

## PC (FIFA 23 via EA App / Steam)

### Option A: Windows hosts file

Redirect `utas.fut.ea.com` and related domains to localhost.

```
# C:\Windows\System32\drivers\etc\hosts
127.0.0.1   utas.fut.ea.com
127.0.0.1   utas2.fut.ea.com
127.0.0.1   ea.com
```

The Bridge must listen on port 443 (HTTPS) or 80 (HTTP).
FIFA 23 expects HTTPS — you'll need a self-signed cert and need to trust it.

### Option B: mitmproxy

1. Install mitmproxy
2. Set Windows system proxy to 127.0.0.1:8080
3. Configure mitmproxy to forward FUT traffic to Bridge

```bash
mitmproxy --mode transparent \
  --listen-host 127.0.0.1 \
  --listen-port 8080
```

⚠️ FIFA 23 may use certificate pinning — this is unconfirmed. If pinning is active, the hosts file approach or a traffic-level redirect may be needed instead.

## RPCS3 (PS3 emulator)

RPCS3 has built-in network settings:

1. Open RPCS3 → Configuration → Network
2. Set DNS to point to your OpenFUT Bridge IP
3. Configure `PSN Status` to `RPCN` or custom
4. The Bridge intercepts DNS and HTTP/HTTPS traffic

Research needed: RPCS3 FIFA 23 title ID and specific network behavior.

## Certificate Handling

EA's FUT API uses HTTPS. Options:

1. **Self-signed cert** — generate with `openssl` and add to system trust store
2. **HTTP downgrade** — if the client accepts HTTP (unlikely for production)
3. **Traffic-level redirect** — use iptables/nftables to redirect port 443 traffic
4. **No cert** — if FIFA 23 PC doesn't verify certs (to be tested)

### Generating a self-signed cert

```bash
openssl req -x509 -newkey rsa:4096 -keyout key.pem -out cert.pem -days 365 -nodes \
  -subj "/CN=utas.fut.ea.com"
```

---

## Status

🔴 Not tested yet. All of the above is research / theoretical.
The first step is to capture real FIFA 23 traffic with mitmproxy and document actual endpoints.

---

## Next Steps

1. Set up mitmproxy on a FIFA 23 PC
2. Start FIFA 23 and navigate to FUT mode
3. Export the mitmproxy capture
4. Add real endpoints to `docs/endpoint-map.md`
5. Add mappings to `src/mapper.rs`
