Forward Proxy vs Reverse Proxy: Direction, Purpose, and Examples
Forward proxy sits in front of clients, hides their identity from the server. Reverse proxy sits in front of servers, hides their identity from clients. Table + examples.
Updated 12 Sept 2026·7-row comparison
Quick answer
Forward proxy — you use one to reach a server (browser → proxy → destination). Reverse proxy — a server operator puts one in front of their infrastructure (client → reverse-proxy → app servers).
TL;DR
Forward proxy sits between clients and the internet — it hides the client from the server (AnyProxy, corporate web filters). Reverse proxy sits between the internet and servers — it hides the server from clients (Nginx, Cloudflare). Same "middleman" idea, opposite directions.

Context
Why this comparison matters
The word "proxy" is direction-agnostic — it just means "stand-in". Which direction matters, and the two directions solve completely different problems. Forward proxies enable client-side access control and anonymity; reverse proxies enable server-side load balancing, TLS termination, and caching.
Pick Forward proxy when
Forward proxy is right
You are a user wanting to reach a blocked page.
You are a corporate admin wanting to filter what users can reach.
You are an anonymity system (Tor uses many forward proxies chained).
You are debugging by inspecting outbound client traffic.
Pick Reverse proxy when
Reverse proxy is right
You operate a website and want to terminate TLS at one place.
You operate multiple app servers and want to load-balance across them.
You want to cache static assets in front of a dynamic backend.
You want to hide your app servers' IPs from public clients.
What breaks if you pick wrong
Calling AnyProxy a "reverse proxy" would be wrong — reverse proxies serve their operator, not their user. Calling Nginx a "forward proxy" would be wrong — forward proxies serve clients, not the servers they front. The distinction matters for architecture decisions.
FAQ
Questions people ask
Is AnyProxy a forward or reverse proxy?
Forward — you use AnyProxy to reach a destination server. AnyProxy does not sit in front of a destination server; it sits between you and the whole internet.
Is Cloudflare a forward or reverse proxy?
Reverse — Cloudflare sits in front of the origin server. When you request a Cloudflare-protected site, Cloudflare is the reverse proxy that fronts the origin.
Can the same software be both?
Nginx and HAProxy can be configured as either, but any single deployment is one or the other by role.
Are corporate web filters forward proxies?
Yes — a corporate filter (Cisco Umbrella, Zscaler) is a forward proxy configured to inspect and block outbound client traffic.
What is a transparent proxy?
A forward proxy that the client is not explicitly configured for — the network transparently routes traffic through it. Common on hotel Wi-Fi.
