Advertisement 5mBridge — Exclusive FiveM Server Access App | DDoS Protection for your FiveM server

[FRIDAY848]

👋 What is 5mBridge?​

5mBridge is a lightweight desktop app that acts as a secret gate for FiveM servers.
Your server becomes completely invisible to the internet. No one can connect, DDoS it, or even scan it — unless they have 5mBridge running on their PC.
Think of it like this:

Without 5mBridge → Your server doesn't exist to anyone
With 5mBridge → Click CONNECT, play normally ✅

---

😤 The Problem​

Running a private FiveM RP server comes with headaches:

• 😤 DDoS attacks crashing your server mid-session
• 😤 Random players connecting without permission
• 😤 Bots and scanners probing your server 24/7
• 😤 Expensive anti-DDoS services that don't fully work

---

✅ The Solution — 5mBridge​

A custom app inspired by WireGuard but built specifically for FiveM.
How it works:

1. Player launches 5mBridge on their PC
2. Clicks CONNECT — app sends a secret port knock to the server
3. Server recognizes the knock → whitelists the player's IP for 45 seconds
4. App re-knocks every 30 seconds automatically — connection stays alive
5. Player connects FiveM normally → everything works ✅
6. Gate closes 45 seconds after disconnect → server invisible again 🔒

🛡️ Live DDoS Test Results​

We ran a real attack simulation against the protected server:


Total attack probes : 166,643
Data got through : 0 (0%)
Gate status : ✅ HOLDING
TCP flood, UDP flood, connection storms — all blocked.
The FiveM server had zero impact during the entire attack.

🔒 Security Architecture​

Internet/Attackers → VPS TCP Gate → ❌ BLOCKED (no whitelist)

5mBridge Player → Port Knock → ✅ IP Whitelisted
→ FiveM Connect → ✅ Full Access

• TCP gate drops all unknown connections instantly
• UDP relay also blocks unwhitelisted IPs
• 45-second TTL — gate auto-closes after disconnect
• No VPN, no WireGuard adapter — fully compatible with FiveM anti-cheat

❓ FAQ​

Q: Does it slow down my FiveM connection?
A: No. 5mBridge only sends a tiny UDP knock packet. All game traffic is direct.
Q: Does it work with FiveM anti-cheat (adhesive.dll)?
A: Yes! Unlike WireGuard, 5mBridge uses no virtual adapter — zero anti-cheat conflicts.
Q: What happens if I forget to connect 5mBridge?
A: FiveM won't connect — the gate blocks you. Just open 5mBridge, click Connect, retry.
Q: Can attackers steal the knock token?
A: Even if captured, the token alone doesn't help without the server also being online and responsive. TOTP (rotating tokens) upgrade is planned.
Q: Does it affect browser/Discord/other apps?
A: No. 5mBridge does NOT set a proxy — your internet stays 100% normal.

Below is the analysis of Server side when it was under attack


. Here's the comparison: Metric Run 1
Run 2 Average CPU ~5% ~7% Peak CPU 16% 16.1% Idle baseline 2–3% 3–4% Duration 60 sec 60 sec Slightly higher this run (~7% avg vs ~5%) —. VPS status: ✅ Healthy — no CPU bottleneck at all.

DDoS is categorized by OSI layers — here's your coverage:​

---

Layer 3 — Network Layer (IP/ICMP Floods)​

Attack: Ping flood, IP packet flood, ICMP amplification

What attacker does	Your protection
Flood raw IP packets	Windows Firewall drops them
Ping flood	ICMP blocked — server doesn't even respond

Your coverage: ✅ Full — server is invisible to ping, all ICMP filtered

---

Layer 4 — Transport Layer (TCP/UDP Floods)​

Attack: TCP SYN flood, UDP flood, connection exhaustion

What attacker does	Your protection
TCP SYN flood (half-open)	Gate accepts → checks whitelist → RST
TCP connection flood	Tested ✅ — 1,900/sec handled, 0% leaked
UDP flood to port 30125	UDP relay whitelist blocks all unknown IPs
UDP amplification	Windows Firewall + UDP whitelist

Your coverage: ✅ Strong — proven by stress test (500 threads, 0 *****)

---

Layer 7 — Application Layer (HTTP/FiveM Protocol Flood)​

Attack: HTTP request flood, FiveM protocol abuse, whitelist bypass

What attacker does	Your protection
HTTP flood to port 30125	Gate blocks before reaching FiveM
FiveM connection spam	Gate blocks — FiveM never sees it
