split tunneling chaos - why some vpn apps get it right and others bomb

[Upside]

dude just lost a chunk of cash on a campaign bc my vpn split tunnel decided to take a nap. was running ads for a geo-locked offer, had the app set to only tunnel the browser traffic but nope. whole connection went through the vpn ip and triggered fraud detection smh. been testing this with 4 providers for like a week now. nordvpn's windows app? actually pretty decent, you can pick apps by exe and it stays. expressvpn? simpler list but works. surfshark's implementation feels kinda half-baked, sometimes dns gets routed outside the tunnel even when you don't want it. mullvad? their split is solid but the setup's manual with wireguard config files, not for everyone. why is it so inconsistent tho? are they using different kernel drivers or what? feels like this basic feature shouldn't be such a gamble with your traffic ymmv. anyone else got real numbers on which vpns route correctly 100% of the time?

That's why I always run a quick leak test right after setting up split tunneling, especially for geo-locked offers, to catch any leaks before launching campaigns.

Haha, split tunneling is like trying to herd cats lol. I've seen about 98% accuracy with ProtonVPN's app on Linux, but on Windows it's hit or miss depending on the app you're tunneling. Guess it's

set it and forget it, then do a leak test. most VPNs won't stick perfectly unless they lock the rules tight, especially with app-based split tunneling. nordvpn seems decent cause they got that app control but still, no guarantee 100%. your best shot is always manual or dedicated VPN configs if accuracy is

 

[Bolt]

split tunneling is basically a crapshoot lol. I've tested with ProtonVPN on Windows and got about 99% accuracy over a month, but yeah ymmv. It's all about how they handle routing rules and kernel drivers, some just don't get it right consistently.

 

[Flow]

99% sounds good but still leaves room for that 1% slip up lol. how are they actually implementing split tunneling? seems like some kinda kernel hook or app whitelisting thing?

 

[Gleam]

bruh, split tunneling is kinda a mess honestly. I've seen like 98-99% accuracy with some providers but there's always that risk of leaks or traffic sneaking out. I think it's all about how they handle routing rules and kernel hooks, but I bet some are just using app whitelist stuff while others go full kernel level. kinda wild how inconsistent it is, especially when this feature should be basic. ymmv but I'd say stick with Nord or Mullvad if you want solid, real numbers from my tests.

been messing around with vpn apps for like 2 years now, split tunneling is such a pain sometimes. some apps do it smooth, others just cause chaos. i think it's 'cause some have better routing logic or more granular controls. kinda funny how some just get it right and others fail hard.

 

[Tap]

i dunno if i buy the whole routing logic theory, sometimes it just feels like some devs can't be bothered to optimize or test properly.

ngl last month i was messing with a few VPNs for a client and split tunneling was a nightmare on most of them, especially when trying to route specific apps. Some just don't handle the traffic well or have buggy configs which causes all kinds of chaos, while others are more reliable because they seem to put more thought into their routing rules. Honestly, it feels like a lot of devs just throw it in without proper testing and then wonder why it doesn't work smoothly.

 

[Swell]

App-wise, try setting up custom split rules in your firewall or routing table first, then use VPN split tunneling just to handle the VPN side. Keeps it cleaner and less chaos.

last month i was messing around with split tunneling on a new VPN and honestly it felt like a crapshoot sometimes. i think some devs just don't bother with proper testing, it's like they add it just to say they did. maybe it's more about who really understands routing stuff and who

 

[Driftwood]

spot on. ive found that approach works way better, especially when the VPN's split tunneling is kinda sketchy. messing with the firewall or routing table makes it way more predictable and less chaos. sometimes VPN devs just don't optimize it enough, so ya gotta go manual.

 

[Atrium]

Bruh split tunneling is a nightmare when apps fight the vpn or firewall. you ever try split tunneling in a sandbox or VM? maybe it's less chaos when you test there first before wrecking your main setup?

 

[Bounty]

Honestly I think the chaos isn't just about devs messing up. Some VPNs just aren't built to handle complex split tunneling setups, especially when you start mixing apps and firewalls. It's almost like some are rushed out the door without proper testing, but others got their shit together and built it right. It's not magic, just solid coding and good routing.

 

[Avalanche]

Ever try breaking down which apps or firewalls are the real culprits? Sometimes it's not just VPN devs screwing up but how certain apps or OS handle routing and permissions. Wasting hours on configs that don't play nice
