## Stage3:

* Point-to-point Tunnel w/ no Encryption
* Server gets client's addr from first packet
* Add packet counter to detect skipped and late packets

### Learnings

* Directional packet loss is an issue.
  * Sending to hetzner: ~380 Mbits/sec
  * From hetzner: ~800 Mbits/sec
* Runs of dropped packets are generally small < 30
  * Saw a few cases of 100-200
* Runs of correctly-sequenced packets are generally >> drops
* Late packets aren't so common
* Dropping late packets causes large slow-down.
