This Proxy Setup Is Dominating Tech Forums

“Kad nema vjetra, veslaj.” (When there’s no wind, row.) In today’s networking landscape, when direct access is blocked or privacy is compromised, those who know how to “row” with a clever proxy setup are setting the pace on tech forums. The proxy setup currently dominating discussions is a chained, containerized proxy stack combining Squid, 3proxy, and WireGuard—delivering unmatched flexibility, security, and scalability.

Why This Proxy Stack?

Like the Siege of Sarajevo, resilience and adaptability are essential. The Squid + 3proxy + WireGuard stack offers:

• Layered security: Each proxy layer mitigates distinct threats.
• Protocol diversity: Supports HTTP/HTTPS, SOCKS5, and encrypted tunnels.
• Simple containerization: Rapid deployment and isolation with Docker.
• Bypass sophistication: Evades firewalls and geo-restrictions with ease.

Architectural Overview

Layer	Purpose	Key Features	Example Container Image
WireGuard	Encrypted Tunneling	Fast, modern VPN	linuxserver/wireguard
3proxy	SOCKS5/HTTP Proxy	Lightweight, custom authentication	z3APA3A/3proxy
Squid	Caching HTTP/HTTPS Proxy	ACLs, caching, SSL bump, logging	sameersbn/squid

Step-by-Step Deployment

1. Preparing the Environment

Install Docker and Docker Compose:

sudo apt update
sudo apt install docker.io docker-compose -y

2. WireGuard Container Setup

Create wg0.conf (WireGuard Quickstart):

[Interface]
PrivateKey = <YourPrivateKey>
Address = 10.0.0.1/24
ListenPort = 51820

[Peer]
PublicKey = <PeerPublicKey>
AllowedIPs = 10.0.0.2/32

docker-compose.yml:

version: '3'
services:
  wireguard:
    image: linuxserver/wireguard
    cap_add:
      - NET_ADMIN
      - SYS_MODULE
    environment:
      - PUID=1000
      - PGID=1000
      - TZ=Europe/Sarajevo
    volumes:
      - ./wg0.conf:/config/wg0.conf
    ports:
      - "51820:51820/udp"
    restart: unless-stopped

Bring up the container:

docker-compose up -d wireguard

3. 3proxy Container Setup

Create a custom 3proxy.cfg (3proxy Config Examples):

nscache 65536
timeouts 1 5 30 60 180 1800 15 60
users admin:CL:password123
auth strong
proxy -n -a -p3128 -i0.0.0.0 -e10.0.0.1
socks -p1080 -i0.0.0.0 -e10.0.0.1

docker-compose.yml (add to previous file):

  3proxy:
    image: z3apa3a/3proxy
    volumes:
      - ./3proxy.cfg:/etc/3proxy/3proxy.cfg
    network_mode: "service:wireguard"
    depends_on:
      - wireguard
    restart: unless-stopped

---

4. Squid Container Setup

Squid’s squid.conf (Squid Official Documentation):

http_port 8080
cache_mem 128 MB
maximum_object_size_in_memory 8 KB
cache_dir ufs /var/spool/squid 100 16 256
access_log /var/log/squid/access.log squid
acl localnet src 10.0.0.0/24
http_access allow localnet
http_access deny all
cache_peer 10.0.0.1 parent 3128 0 no-query default

docker-compose.yml (add to previous file):

  squid:
    image: sameersbn/squid
    volumes:
      - ./squid.conf:/etc/squid/squid.conf
    ports:
      - "8080:8080"
    depends_on:
      - 3proxy
    restart: unless-stopped

---

Request Flow Through the Stack

1. Client → Squid (HTTP/HTTPS)
2. Squid forwards to 3proxy (SOCKS5/HTTP)
3. 3proxy routes via WireGuard tunnel
4. Destination

Diagram:

[Client]
   |
[Squid:8080]
   |
[3proxy:3128/1080]
   |
[WireGuard:10.0.0.1]
   |
[Internet]

Security Considerations

• Authentication: Always enable authentication in 3proxy and Squid.
• Firewall: Restrict external access to proxy ports.
• Logs: Monitor Squid and 3proxy logs for suspicious activity.
• Update Regularly: Apply security patches; vulnerabilities in proxies are often exploited.

Real-World Use Cases

Use Case	Why This Stack?	Bosnian Analogy
Penetration Testing	Multiple protocol support, privacy	“Kao diverzant u šumi”
Web Scraping	IP rotation, caching, bypass restrictions	“Kao zmija kroz travu”
Corporate Access Control	Detailed ACLs, logging, encryption	“Vodi računa kuda prolaziš”
Geo-unblocking	Tunneling through restrictive regimes	“Preko brda, preko dolina”

Troubleshooting Tips

• Connection refused?
  Check container logs and ensure inter-container networking is set properly.

• Slow performance?
  Optimize Squid cache and 3proxy timeouts. Don’t let your proxy “spava pod jabukom”.

• Authentication failures?
  Inspect user/password setup in 3proxy and Squid; watch for encoding issues in configs.

In the world of proxies, every setup leaves a trace—choose yours wisely and with purpose.
