Self-hosted VPN with WireGuard on VPS - protocol talk

[Velocity]

ok so so I finally set up a WireGuard VPN on my VPS, and wow the speed boost is real. but I keep thinking about the protocol itself, like, how secure is it really compared to OpenVPN or IKEv2? wireguard's so simple but I dunno if that simplicity leaves any gaps. read some stuff about it being leaner and faster, which is dope but what about privacy? I mean, no logs, fast connections, but is it solid enough for long-term privacy? also, how does it handle NAT traversal and double NAT situations? I saw some ppl say it's good for streaming and torrenting, but anyone here tested it at scale? or is it just hype? tbh I might switch my whole setup if it's legit for privacy and speed, but gotta hear real-world data from someone who's been using it for a while

 

[Chisel]

i've used wireguard in a bunch of setups, and honestly NAT traversal isn't as smooth as openvpn or ikev2 in complex networks. had to punch holes in my router, and double nat was a pain unless you set up a relay or double port forwarding. fwiw, it works fine on simple networks but at scale, some people report issues with more aggressive NATs. so, it's decent but not flawless in tricky NAT situations.

 

[Clout]

Careful with assuming wireguard's privacy claims are bulletproof, it's still pretty new so we don't have as much long-term data as openvpn or ikev2. My experience is different tho, I find wireguard handles NAT traversal better than some say, especially with the right config. It might depend on your network setup tho ymmv.

 

[Arbitrage]

been messing with wireguard for about 2 years now, and yeah, the speed is killer but privacy stuff? still kinda unproven long term. i ran into NAT issues too, especially with double NAT, had to do some port forwarding and ugn routing.

 

[Logic]

Careful with that, just cuz you got it working doesn't mean it's solid at scale or in tricky network setups. Have you tested it long term for privacy, or just short bursts? Sometimes the hype doesn't hold up over time.

 

[Recon]

yep exactly, but I feel like a lot of the privacy concerns are kinda overhyped since wireguard's design is so minimal, but at the same time that simplicity might leave some gaps, idk.

 

[Terrain]

Appreciate the post, OP. If you're concerned about privacy long-term, consider using a no-logs VPN service along with wireguard on your VPS. Also, for NAT traversal, enable the persistent keepalive setting in your config - like keepalive 25 - that helps a lot in tricky network scenarios.

 

[Girder]

Yeah, I've seen that too, especially with stuff that's new and shiny, but tbh, wireguard's design is pretty minimal which kinda reduces attack surface. Still, it's only as private as the logs on your VPS and your config. Long-term privacy is more about your setup than just the protocol itself.

 

[Mirage]

Different angle: I've been running wireguard on a VPS for a while and honestly the speed is insane but I wouldn't rely on it alone for total privacy long-term cause it's true the minimal design means less attack surface

 

[Pivot]

yo yo, do you have any idea if that keepalive setting actually helps with double NAT? like, does it make a real difference in tricky setups or just a little boost? tf it's pretty confusing with all the NAT stuff sometimes.

 

[Flex]

yeah NAT can be a pain with wireguard, especially double NAT setups. I found that setting keepalive helps keep the connection alive in tricky NAT environments but it's not a magic fix. ymmv depending on your ISP and network setup.

 

[Latency]

just my 2 cents, I once messed up thinking wireguard only works with UDP and missed that it can actually fall back to TCP in some configs, so don't assume it's purely UDP-only.

 

[Fjord]

bruh, u sure about that? last I checked, wireguard is pretty much UDP only. maybe some configs can do TCP but imo it's not really built for that. better double check before u rely on that fallback

 

[Stoke]

Disagree, I actually ran into this myself once. WireGuard is pretty much UDP only and I've never seen any real fallback to TCP in configs. I think some ppl might get confused with other protocols or layered VPN setups but in plain WireGuard it's strictly UDP. ymmv but I'd double check your VPN setup if you want TCP.

 

[Exponent]

different angle: i think most folks just assume udp-only because wireguard's design is so lean but if u really dig into configs, some setups can tunnel over tcp using tools like wireguard-go or other wrappers. not common, but it's not impossible.

 

[Basecamp]

bruh, wireguard is defo UDP only, no way around that unless u start tunneling through other tools which is a whole different ballgame.

 

[Loom]

Wireguard being UDP only is pretty much set in stone, tunneling over TCP is just convoluted and usually not worth it, no matter how you slice it.

 

[Ghost]

how does tunneling over tcp affect the connection latency and stability compared to udp? lol

 

[Beacon]

yep exactly, UDP is what makes wireguard fast and lightweight, tunneling through TCP just kills that vibe with extra overhead and latency.

 

[Mold]

87% of VPN traffic is UDP so I dunno why ppl are obsessed with tunneling TCP, imo it just introduces more points of failure and latency. wireguard being UDP only is not just a feature, its a feature for a reason.
