- Sets up redirection with newly-started (or newly-added, previously-started) application pods such that traffic from application pods is forwarded to the local node's ztunnel pod.
- Configures required iptables, sockets, and packet routing miscellanea within the `ztunnel` and application pod network namespaces to make that happen.

This component accomplishes that in the following ways:

## Traffic routing

Based on the three [redirection](#redirection) paths, the ztunnel has three primary types of traffic it handles.

### Outbound

Requests leaving a pod go through the "outbound" code path on port 15001.
