That's definitely real. Normal, unobfuscated VPN will result in packet drops after a couple of minutes. Even obfuscated VPN will trigger packet drops if you send too much traffic.
- johansch 10y agoThanks for that - it's great to have a confirmation. Obfuscated/unobfuscated VPN traffic, what is the actual difference at protocol level?
