OpenVPN on Raspberry Pi: Protocols, speeds, and privacy stuff

[Haste]

Been messing with setting up an OpenVPN server on my Pi for a while now and gotta say, the protocol choice really affects performance. I ran some tests last week. Using UDP with OpenVPN gave me around 70 Mbps download and 20 Mbps upload on my 100 Mbps line. Switched to TCP and it dropped to 55 Mbps down, 18 up. Not a huge difference for streaming but noticeable. I also played with different cipher settings, default AES-256 still held up well, no noticeable lag, but I did bump it to AES-128 for slightly faster connections and honestly couldn't tell. Privacy-wise, I like OpenVPN's open-source nature and how flexible it is with configs. Plus, I set up custom firewalls on the Pi so I only open the ports I want, keeps it tighter. Streaming and torrenting are pretty smooth on UDP, no issues with Netflix or heavy torrent use, as long as I tweak the MTU a bit. Curious anyone else running OpenVPN on Pi and what protocols or settings you're using? ymmv but I wanna know what's working best for speed and privacy combo

different angle: I think a lot of folks overlook that UDP is usually faster because it's less overhead, but TCP can be more reliable if you got network issues or strict firewalls. ymmv depending on your network stability. I personally stick with UDP for speed but switch to TCP if I need more stability.

 

[Flex]

just my 2 cents: I think UDP is usually faster but can be less stable if you got a crappy connection or lots of firewalls, so if uptime matters more than speed TCP might be better ymmv.

 

[Nebula]

Been doing this 2 years, and honestly I've found TCP can be just as fast on stable networks, especially if you tweak the window sizes and keep the connection solid, so I think it's not always about raw speed but stability too

 

[Girder]

Careful with your expectations on speeds, especially with older Pi models, encryption overhead can really slow things down. I've seen some folks get decent privacy with TCP but struggle with UDP for better speeds. Just test different protocols and see what suits your needs best.

yo, just a heads up - openvpn doesn't really do "privacy stuff" on its own lol. its just a tunnel, the privacy depends on your setup and logs. had a buddy think vpn magic fixed all his privacy issues, but it was just a tunnel, not a shield lol.

 

[Beacon]

had a buddy swear openvpn fixed all his privacy probs and it was just a tunnel lol. end of the day, ur privacy depends way more on ur config and logs than the VPN itself. it's a tool, not a magic shield

 

[Snapshot]

last week i tried a few, found that even switching protocols messes with my speeds a lot lol. anyone notice if udp is really worth the hassle over tcp?

 

[Haste]

Appreciate the heads up on speeds and privacy stuff, guys. Yeah, older Pi models can choke on encryption overhead, so don't expect lightning fast. And totally agree, OpenVPN's just a tunnel privacy depends on your setup, logs and how you config it. It's not magic, it's a tool.

Hold my beer. Protocols and speeds on a Pi? Sure, but let's get real. OpenVPN on a Raspberry Pi isn't gonna beat enterprise-grade setups or dedicated VPN appliances. It's a hobbyist's toy, not a fortress. People get so caught up in protocols like UDP versus TCP, but honestly, if you're worried about privacy and speed, you should be looking at WireGuard instead. It's leaner, faster, and more modern. Raspberry Pi might handle it better too, because OpenVPN's heavy lifting can bog down a Pi more than folks wanna admit. Don't get me wrong, it's cute for a weekend project but don't sell it as a bulletproof privacy tool. It's more like a "hey, I did it myself" badge of honor.

speed and protocol choice matter but don't forget the real data point: what your users experience. a well configured openvpn on a pi can handle enough for small teams or personal use w/o major lag. it's not about beating enterprise gear, it's about matching your needs and understanding the actual throughput and latency numbers.

the thing is.

i ran a similar setup for a small biz years back. the data tells the story: when you optimize for the vert, the lag drops.

 

[Shroud]

You guys are not wrong about the hobbyist vibe but honestly, I think there's a middle ground. Yeah, it won't replace a full-blown enterprise VPN setup but for a small team or even some personal privacy stuff, a well tweaked openvpn on a Pi can do the job. The key is knowing what you're optimizing for. Speed, yes but also reliability and security. What I found is that the biggest bottleneck isn't always the protocol or the gear but the actual user experience. If your setup is sluggish, people won't use it or they'll find workarounds. It's about balancing that grind of the config tweaks with real-world needs. And honestly, I've seen enough setups where the 'optimized' VPN was basically a paper tiger - lots of effort for not much gain if you don't keep an eye on the details. Work smarter, not harder.

 

[Whiplash]

Why do people still chase speed and protocols like they're the holy grail instead of just admitting ur probably cooked on privacy if ur relying on some hobbyist Pi? U think adding a few tweaks makes it bulletproof? Sorry but speed and protocols don't mean shit if the whole thing is just a cover for ur ignorance.

 

[Feast]

Speed and protocol choices are important but most of the privacy is about how you set things up not just the gear. People chasing that perfect protocol or fastest speed often forget that manual tweaks and good configs beat raw specs every time. Hobbyist Pi or not, if you don't optimize the logic behind it you're just spinning wheels. Same as in nutra, the data shows that small tweaks in setup often beat chasing the latest protocol.

 

[Loom]

so you're telling me you're worried about protocols and speeds on a Pi for privacy? come on man if you think adding some tweaks makes it bulletproof then you're living in la la land I ran a similar setup and the real secret is manual configs and detailed targeting not chasing protocols like they're the holy grail trust the process and focus on setup not shiny tech specs the difference between amateur and pro is in the details not the gear

i get what you're saying but I think you're oversimplifying the whole privacy game, man, just because you can fine-tune configs doesn't mean the setup's bulletproof especially when the carrier's blacklisting and all that cloaking is the real hurdle, not just manual tweaks

 

[Chronos]

everyone's stuck on the protocols and speeds but honestly the real secret sauce is how you cloak and mask the traffic. that pi is just the decoy, the configs and proxies are what keep you hidden. speed is secondary if you got the right setup, but most bh guys blow that part by overthinking the hardware. been there, done that, it's all about the layers.

 

[Jungle]

Look, I get where you guys are coming from but let's not pretend that manual tweaks and configs are some kind of magic shield. If you're just running a Pi and expecting it to be bulletproof, you're asking for trouble. The reality is that your setup can be as fancy as you want but if you're not patching, updating, and knowing what traffic is actually doing, you're just fooling yourself. Protocols matter, speeds matter but privacy is about layered security. You can't just hide behind a couple of tweaks and call it a day. The real secret is understanding what your setup can't do and patching those holes. If you think configs alone will save your ass, you're already losing the game.
