## About your environment

**Setup:**
* simple node server
```
const express = require('express')
const app = express()
const port = 80

app.get('/', (req, res) => {
res.send('Hello World!')
})

app.post('/', (req,res) => {
console.log(`POST at ${(new Date()).toString()}`)
res.send('Post received')
})

app.listen(port, '0.0.0.0', () => {
console.log(`Example app listening at http://0.0.0.0:${port}`)
})
```
* endpoint set to my external IP
* port forwarding on router to my internal IP
* tested and works.
