## 1. Stack overview
|
||
|
||
```
|
||
Internet / LAN
|
||
│
|
||
▼
|
||
DNS (rpc-http-pub.d-bis.org, rpc.d-bis.org, rpc2.d-bis.org, rpc.defi-oracle.io, etc.) → 76.53.10.36
|
||
│
|
||
▼
|
||
UDM Pro port forward 76.53.10.36:443 → 192.168.11.167:443
|
||
│
|
||
▼
|
||
NPMplus (192.168.11.167:443) – TLS termination, Host-based routing
|
||
│
|
||
▼
|
||
Besu RPC – VMID 2201 (192.168.11.221:8545 HTTP, :8546 WebSocket)
|
||
│
|
||
▼
|
||
Response: eth_chainId → 0x8a (Chain ID 138)
|
||
```

|
||
|
||
## 2. Validation results
|
||
|
||
| Check | Result |
|
||
|-------|--------|
|
||
| **DNS** | Public hostnames resolve to 76.53.10.36 |
|
||
| **TLS** | Valid Let's Encrypt; CN matches hostname; TLS 1.3 |
|
||
| **Proxy** | NPMplus routes by Host to VMID 2201 |
|
||
| **Upstream** | Besu RPC (192.168.11.221:8545 / :8546) reachable and responsive |
|
||
| **RPC** | `eth_chainId` returns `0x8a` (138) |
|
||
| **Chain** | Defi Oracle Meta Mainnet – sovereign EVM, no mainnet/testnet collision |
|
||
|
||
**Validation command** (from a host that can reach NPMplus, e.g. LAN with Split DNS or `--resolve`):
|
||
|
||
```bash
|
||
curl -sk --resolve rpc-http-pub.d-bis.org:443:192.168.11.167 \
|
||
https://rpc-http-pub.d-bis.org \
|
||
-H "Content-Type: application/json" \
|
||
-d '{"jsonrpc":"2.0","method":"eth_chainId","params":[],"id":1}'
|
||
# Expected: {"jsonrpc":"2.0","id":1,"result":"0x8a"}
|
||
```

## 3. Public endpoints
|
||
|
||
| Endpoint | Type | Backend |
|
||
|----------|------|---------|
|
||
| https://rpc-http-pub.d-bis.org | HTTP RPC | 192.168.11.221:8545 |
|
||
| wss://rpc-ws-pub.d-bis.org | WebSocket RPC | 192.168.11.221:8546 |
|
||
| https://rpc.d-bis.org | HTTP RPC | 192.168.11.221:8545 |
|
||
| https://rpc2.d-bis.org | HTTP RPC | 192.168.11.221:8545 |
|
||
| wss://ws.rpc.d-bis.org | WebSocket RPC | 192.168.11.221:8546 |
|
||
| wss://ws.rpc2.d-bis.org | WebSocket RPC | 192.168.11.221:8546 |
|
||
| https://rpc.defi-oracle.io | HTTP RPC | 192.168.11.221:8545 |
|
||
| wss://wss.defi-oracle.io | WebSocket RPC | 192.168.11.221:8546 |
|
||
|
||
**Explorer**: https://explorer.d-bis.org
|
||
**Chain ID**: 138 (`0x8a`)

||
|
||
## 4. Operational notes
|
||
|
||
- **LAN access**: From inside the same network, public hostnames may not resolve back (NAT hairpin). Use Split DNS (internal A records to 192.168.11.167) or the `--resolve` curl pattern for testing.
|
||
- **Port forwarding**: 76.53.10.36:80 and :443 → 192.168.11.167 (NPMplus). Confirmed on UDM Pro.
|
||
- **No auth**: Public RPC endpoints do not require API keys or auth.
