HTTP, SOCKS5 or a full VPN tunnel: which connection your job needs
Three ways to route traffic through a mobile IP, what each one carries, and the QUIC/WebRTC leaks that quietly expose your real address when you pick the wrong one.

"Which port do I use?" is really "how much of my traffic do I want on the mobile IP?" HTTP, SOCKS5 and a VPN tunnel answer that at three different scopes — and the gap between them is exactly where real-IP leaks hide.
HTTP(S) proxies — the web-traffic default
An HTTP proxy operates at the application layer: it understands the web requests it carries, handles HTTPS endpoints natively, and can cache repeated assets. For browser-based work it's the right first choice — and for platforms like Facebook, plain HTTP proxying often outperforms SOCKS because it speaks the protocol it's carrying. HTTP proxies are TCP-only, which matters for the leak discussion below.
SOCKS5 — anything that speaks TCP
SOCKS5 is lower-level and protocol-agnostic: it forwards any TCP stream, which makes it the right pick for bots, automation frameworks, antidetect browsers, and specialized tools that don't speak plain HTTP. If a tool misbehaves over HTTP, switching it to SOCKS5 is the cheapest experiment you can run. SOCKS5 also *defines* a UDP mode, which matters for the QUIC discussion — but browsers, importantly, don't use it automatically.
A VPN tunnel — the whole device
A proxy only carries the sockets an app deliberately sends through it. A VPN operates at the OS level: it captures *every* app, every DNS query, and — crucially — UDP traffic like QUIC and WebRTC that a proxy never sees. If you're running arbitrary OS-level tooling, an emulator, or you simply want everything on the carrier IP with no leak surface, that's the VPN tier's job. See WireGuard vs OpenVPN for choosing between the two.
The leak that catches people: QUIC and WebRTC
Here's the trap. Modern browsers use HTTP/3, which runs over QUIC, which runs over UDP. When you configure a browser with a TCP-only HTTP or SOCKS proxy, its QUIC traffic isn't proxied at all — the browser opens it straight from your real network interface, revealing your real IP. WebRTC does the same thing through a different door: it opens UDP straight to STUN servers, bypassing an HTTP/SOCKS proxy entirely.
How to pick — and how to stay leak-free
- 01Browser-based account work or web scraping → HTTP(S) first; it understands the traffic and caches.
- 02Bots, automation, antidetect tools, anything speaking raw TCP → SOCKS5.
- 03Whole-device coverage, emulators, or zero tolerance for leaks → a VPN tunnel.
- 04On any proxy tier, harden the browser: disable WebRTC, and either force HTTP/2 (TCP) or accept that QUIC needs the VPN tier to be covered.
Is SOCKS5 more secure than HTTP?
It's not about security — both carry your traffic to the same mobile exit. SOCKS5 is more *general* (any TCP stream), HTTP is more *specialized* (understands and caches web traffic). Pick by what your tool speaks, not by a security ranking.
Why does a proxy leak my real IP over WebRTC?
WebRTC opens UDP connections straight to STUN servers from your real interface, bypassing an HTTP or SOCKS proxy completely. The proxy never sees that traffic, so it can't route it. Disable WebRTC in the browser, or use a full VPN tunnel that captures UDP too.
Do I need the VPN tier?
Only if you run traffic a proxy-aware app won't send through the proxy — OS-level tools, emulators, or QUIC/UDP-heavy apps. If your whole workflow lives inside a proxy-aware antidetect browser, HTTP or SOCKS5 is enough.
