NGINX Plus terminates the TCP connection or UDP session and reads the request data within.
Remote clients make TCP connections or send UDP datagrams directly to the NGINX Plus reverse proxy at its published IP address and port. Traffic handling with NGINX Plus serving as a standard reverse proxy In this mode of operation, NGINX Plus manages separate client‑side and upstream‑side TCP connections (for HTTP and TCP traffic) or UDP sessions in order to control the communication between the remote client and the selected upstream server. Unlike a switch or router that simply forwards packets, NGINX Plus operates as a Layer 7 reverse proxy. Introduction: Packet Flow in a Standard Layer 7 Reverse Proxy Only implement these configurations if the standard reverse proxy mode of operation is not sufficient for your application or service. It is complex to deploy and troubleshoot IP Transparency and DSR. Networking configuration on upstream server Networking configuration on NGINX Plus proxy Tc nat rewrites on the intermediate NGINX Plus server Iptables terminates on the NGINX Plus proxy Standard: egress traffic is terminated on the NGINX Plus proxyīetter: egress traffic is forwarded by the intermediate NGINX Plus serverīest: egress traffic is routed directly to the remote client, bypassing NGINX Plus It is applicable to UDP‑based protocols and can be implemented by performing NAT (network address translation) on the origin server or an intermediate router.Īll egress traffic routed to the NGINX Plus proxy and terminatedĪll egress traffic routed through the intermediate NGINX Plus server Direct Server Return (DSR) further arranges that responses from the upstream servers go directly to the remote clients and bypass the intermediate load balancer. It is applicable to TCP‑ and UDP‑based protocols. IP Transparency ensures that the upstream servers observe that each connection originates from the remote client that initiated it. This article describes two additional methods, which apply to TCP and UDP traffic: There are effective workarounds for HTTP and HTTPS traffic, using either the X-Forwarded-For HTTP header or the PROXY protocol. 
This is a challenge if the upstream server needs to determine the true origin IP address (the remote client’s), for example, for authentication or logging purposes. This allows NGINX Plus to apply a number of optimizations and enhancements to the network requests it manages.Īs a consequence, upstream (load‑balanced) servers observe that all traffic originates from an IP address on the NGINX Plus proxy.

For the sake of brevity, we’ll refer only to NGINX Plus.Įditor – This is the fifth in a series of blog posts that explore the new features in NGINX Plus R10 in depth.
The information in this post apply to both NGINX Open Source and NGINX Plus. It explains how you can use a transparent proxy to spoof the source IP address of packets to implement IP Transparency, and how you can implement a load‑balancing mode called Direct Server Return for UDP traffic.
