How we handle this is [under discussion](https://docs.google.com/document/d/1uM1c3zzoehiijh1ZpZuJ1-SzuVVupenv8r5yuCaFshs/edit#heading=h.dwbqvwmg6ud3).

### Inbound

Traffic entering a pod over HBONE will be handled by the "inbound" code path, on port 15008.

- excludeInterfaces
- kubevirtInterfaces
- ISTIO_META_DNS_CAPTURE env variable on the proxy - enables dns redirect
- INVALID_DROP env var on proxy - changes behavior from reset to drop in iptables
- auto excluded inbound ports: 15020, 15021, 15090

The code automatically detects the proxyUID and proxyGID from RunAsUser/RunAsGroup and exclude them from interception, defaulting to 1337
