Wake up, your config died again
At 3 AM, DPI drops active WireGuard sessions. Every. Single. Night.
You don’t notice until morning, until you try to open GitHub or Docker Hub.
Fix:
# systemd timer to restart WG tunnel every 4 hours
sudo systemctl edit wireguard-wg0.service
[Service]
Restart=always
RestartSec=120
Add cron or timer for wg-quick down wg0 && wg-quick up wg0 at 04:00.
No, PersistentKeepalive = 25 doesn’t help against deep packet inspection reset. Tried.
What actually works today (mid 2026)
- WireGuard over TCP tunnel (udp2raw + wg). UDP gets detected in 15 minutes.
- VLESS + Reality (Xray). Hides inside valid TLS like Zoom or Discord traffic.
- AmneziaWG — patched WireGuard with fake packet padding.
Dead:
- OpenVPN TCP/1194 — dead since 2024
- Plain Shadowsocks — DPI kills in 5 mins
- Any public VPN list — blocked in 2 hours after publication
Minimal survival setup
Rent a cheap VPS (€3–4/month, Netherlands or Finland). Deploy:
# Xray install
bash -c "$(curl -L https://github.com/XTLS/Xray-install/raw/main/install-release.sh)" @ install
# Config snippet — VLESS+Reality
{
"inbounds": [{
"port": 443,
"protocol": "vless",
"settings": {
"clients": [{"id": "uuid-gen-here"}],
"decryption": "none"
},
"streamSettings": {
"network": "tcp",
"security": "reality",
"realitySettings": {
"dest": "www.microsoft.com:443",
"serverNames": ["www.microsoft.com"],
"privateKey": "your-key"
}
}
}]
}
Client: NekoBox (Android) or v2rayN (Windows). Don’t use official VPN apps — blocked by domain.
DNS is separate pain
DoH/DoT over 443 works. But RKN filters public DoH servers (Cloudflare 1.1.1.1 blocked in March 2026).
Working:
- Your own
dnscrypt-proxyon the same VPS adguardhomewith encrypted upstream
# adguardhome upstreams
upstream_dns:
- https://dns.google/dns-query
- https://cloudflare-dns.com/dns-query
# fallback to plain DNS over VPN tunnel only
Without VPN — local recursive resolver (Unbound). Slow but undetectable.
Rake
The trap: You set up WireGuard with MTU 1420, runs fine for 2 days. Then one morning — handshake fails, but wg show says connected.
Why: Your ISP upgraded DPI to track UDP handshake patterns, not just packets. WireGuard’s Init message looks the same every time. Machine learning model catches it in 72 hours.
Fix: Add jitter. Randomize handshake interval. Use wg dynamic patch or switch to AmneziaWG with Jc = 3, Jmin = 50, Jmax = 1000.
Don’t overcomplicate
One VPS. One protocol (VLESS+Reality). One client.
Don’t install 5 fallbacks. Don’t use chain proxies. Every extra hop is a new point of failure.
Check your endpoint every morning:
# curl through tunnel
curl --socks5 127.0.0.1:1080 https://ifconfig.co
If timeout — restart tunnel. If handshake but no data — change VPS IP (€0.50–1 for new one).
That’s it. Blocks aren’t smart. They just replay the same DPI rules every night.
