Ask HN: How many days for China Firewall to catch my WireGuard server?

1 z3wasoft3r 1 8/20/2025, 2:37:26 PM

Hello,

Does anyone know how long it typically takes for the Great Firewall to block a WireGuard IP/port combination?

I set up a WireGuard instance on one of my VMs as a backup for a friend who’s visiting China for about a week. They already have NordVPN, but this is just an alternative in case that doesn’t work. From what I’ve read, WireGuard endpoints usually last only a few days before being blocked, but I’m wondering if anyone has recent, first-hand experience. Are we talking closer to two days, or could it last a full week?

Unfortunately, I wasn’t able to get an easy Android setup for Cloak + WireGuard. The devices weren’t rooted, so I couldn’t use Shadowsocks (only supported on older Android versions) or install the cloak-android APK (root required). Since this was a last-minute setup, we ended up going with plain WireGuard.

I tried the same a few years ago, but WireGuard never worked for me. It seemed to be blocked (the protocol).
