How do I preserve source IP with TLS PASSTHROUGH mode on an Istio ingress gateway

fr flag

I have a pod that NEEDS to keep the client cert in tact and terminate TLS at the pod level. For that reason, I’ve got to use TLS passthrough mode.

However, I also need the source IP of the original packet origin. I can’t seem to get TPROXY working on the system due to unknown system requirements

TPROXY mode broken on 1.13.1 · Issue #37701 · istio/istio (github.com)

How can I preserve the source IP header in the packet? Do I need proxy protocol?

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
