I found that only the 'proxy_port' was set in the redirect code of [Cilium](https://github.com/cilium/cilium/blob/beta/service-mesh/bpf/lib/proxy.h#L210), but the 'proxy_ip' of proxy was not set. ![image](https://user-images.githubusercontent.com/8215757/158757340-35f44e91-7759-4fa8-a507-06bc1e228c60.png) ![image](https://user-images.githubusercontent.com/8215757/158757616-f5858ddd-85dc-4711-bcc1-8f469059b72b.png)

背景介绍 ====== MOSN 在 Service Mesh 领域作为东西向 RPC 服务治理网络转发组件已经在社区很多公司都得到了一定实践,为了进一步节省研发运维等相关成本,目前业界也有很多公司在考虑把东西向和南北向数据转发面统一。MOSN 在作为东西 Sidecar 场景当前性能足以,但在作为南北向网关会有一定性能上限(比如单机百万级长连接、高并发等场景)。 解决方案(草案) ====== 为 MOSN 在 Network 层做一个高性能的网络扩展层,使其可以和高性能网络库结合使用(如Nginx、Envoy、OpenResty 等),使其底层网络具备高性能处理的同时,又能复用 MOSN Stream Filter 等能力。 ![image](https://user-images.githubusercontent.com/8215757/106463439-5fe9ce00-64d2-11eb-9697-afd611bafa4c.png) 如上图所示,MOSN 通过扩展一个标准的 GOHPNF(Golang On High...
