📑 Table of Contents Part 1
🔌 What Are Proxy Server Ports
A proxy server port is a numerical identifier (from 1 to 65535) that specifies a particular communication channel on the server. When you connect to a proxy, you specify not only the IP address but also the port, for example: 192.168.1.1:8080
Why Ports Are Important for Proxies
🎯 Key Functions of Ports:
- Service Identification — Different ports for different protocols (HTTP, HTTPS, SOCKS)
- Multiple Services — One IP can host several proxies on different ports
- Bypassing Blocks — Some networks block standard ports; non-standard ones help bypass filters
- Security — Using non-standard ports makes proxy detection more difficult
- Load Balancing — Distributing load across ports
- Firewall Configuration — Access control at the port level
For example, if you see proxy.example.com:8080, the number 8080 is the port. Without specifying the port, the connection will fail.
Port Ranges
📊 Port Classification:
| Range | Name | Description |
|---|---|---|
| 0-1023 | Well-known ports | Reserved for system services (HTTP:80, HTTPS:443) |
| 1024-49151 | Registered ports | Registered by IANA for applications (8080, 3128, 1080) |
| 49152-65535 | Dynamic/Private ports | Dynamic ports for temporary connections |
Proxy servers usually use ports from the 1024-49151 range, although ports 80 and 443 are also popular.
🌐 Standard Proxy Server Ports
In 2025, there are several widely used ports for proxy servers. The choice of port depends on the protocol (HTTP, HTTPS, SOCKS) and the type of use.
Popular Ports by Protocol
| Protocol | Main Ports | Application | Popularity |
|---|---|---|---|
| HTTP | 80, 8080, 3128, 8118 | Web traffic, scraping, browsers | ⭐⭐⭐⭐⭐ |
| HTTPS | 443, 8443 | Secured SSL/TLS traffic | ⭐⭐⭐⭐⭐ |
| SOCKS4/5 | 1080, 1085 | Universal proxy, torrents, gaming | ⭐⭐⭐⭐ |
| Squid | 3128, 8080 | Caching proxies | ⭐⭐⭐ |
| Transparent | 8080, 3128 | Corporate networks | ⭐⭐⭐ |
🌍 HTTP Ports: 80, 8080, 3128, 8118
🔵 Port 80
Standard HTTP port — used for unencrypted web traffic
✅ Advantages:
- Universally supported
- Does not raise suspicion with firewalls
- Wide compatibility
❌ Disadvantages:
- Often blocked on corporate networks
- Lack of encryption
- System port (requires root)
🟡 Port 8080
Most popular HTTP proxy port — an alternative to port 80
✅ Advantages:
- Most used port for HTTP proxy
- Does not require root privileges
- Supported by all clients
- Good compatibility
❌ Disadvantages:
- May be blocked by firewalls
- Frequently scanned by bots
💡 Recommendation: Use 8080 as the default port for HTTP proxies
🟢 Port 3128
Standard Squid port — used by caching proxy servers
Squid is the most popular proxy server software, making port 3128 a de facto standard for caching and forwarding.
When to use:
- Corporate networks
- Caching proxies
- Content control
- Squid-based solutions
🟣 Port 8118
Privoxy port — used for content filtering and anonymization
Privoxy is a proxy with features for ad filtering, tracker blocking, and privacy protection.
Features:
- Ad filtering
- Tracker blocking
- Header modification
- Tor integration
Examples of HTTP Port Usage
Curl commands for different ports:
# Port 8080 (most common)
curl -x http://proxy.example.com:8080 https://example.com
# Port 3128 (Squid)
curl -x http://proxy.example.com:3128 https://example.com
# Port 80 (standard HTTP)
curl -x http://proxy.example.com:80 https://example.com
# With authentication
curl -x http://username:password@proxy:8080 https://example.com
🔒 HTTPS Ports: 443, 8443
HTTPS proxies use SSL/TLS encryption to protect traffic. In 2025, this is the standard for secure connections.
🔴 Port 443
Standard HTTPS port — used for secure HTTPS connections
🎯 Why 443 is the best choice:
- Masked as regular HTTPS traffic — rarely blocked by firewalls
- Maximum compatibility — works in all networks
- Deep Packet Inspection bypass — harder to detect the proxy
- Corporate networks — usually not blocked
- SSL/TLS encryption — data security
💡 2025 Tip: Use port 443 for maximum stealth and bypassing blocks. It looks like regular HTTPS traffic to a website.
🟠 Port 8443
Alternative HTTPS port — for additional SSL services
When to use 8443:
- Port 443 is already occupied by another service
- Need to separate traffic between services
- Alternative if 443 is blocked
- Administrative panels
- Test environments
⚠️ Attention:
Port 8443 is less common and might raise suspicion with firewall systems. Use 443 if possible.
HTTP CONNECT Method for HTTPS Proxies
HTTPS proxies use the CONNECT method to establish a tunnel between the client and the target server. This allows encrypted SSL/TLS traffic to be passed through the proxy.
Example CONNECT Request:
CONNECT example.com:443 HTTP/1.1
Host: example.com:443
Proxy-Authorization: Basic dXNlcm5hbWU6cGFzc3dvcmQ=
# Proxy responds:
HTTP/1.1 200 Connection Established
# After this, all traffic is encrypted with SSL/TLS
⚡ SOCKS Ports: 1080, 1085
SOCKS (Socket Secure) is a universal proxy protocol that operates at a lower level than HTTP. It supports any type of traffic: HTTP, HTTPS, FTP, SMTP, P2P, gaming.
🔵 Port 1080 — SOCKS Standard
Port 1080 is reserved by IANA (Internet Assigned Numbers Authority) specifically for SOCKS proxies. This is the official standard port.
✅ Advantages of SOCKS5 on port 1080:
- Universality — works with any protocol (HTTP, FTP, SMTP, SSH, torrents)
- UDP Support — for gaming, video calls, streaming
- Authentication — supports username/password
- IPv6 Support — works with modern networks
- No data modification — the proxy simply forwards packets
- Lower overhead — faster than HTTP proxies
When to use SOCKS5:
| Scenario | Why SOCKS5 |
|---|---|
| Torrents | P2P protocols do not work via HTTP proxies |
| Online Gaming | Requires UDP and low latency |
| Email Clients | SMTP/IMAP/POP3 support |
| FTP/SSH | Protocols outside of HTTP |
| Streaming | UDP for video/audio streams |
SOCKS4 vs SOCKS5
| Feature | SOCKS4 | SOCKS5 |
|---|---|---|
| Authentication | ❌ No | ✅ Username/Password |
| UDP Support | ❌ TCP only | ✅ TCP and UDP |
| IPv6 | ❌ IPv4 only | ✅ IPv4 and IPv6 |
| DNS Resolution | ❌ Client | ✅ Proxy (Remote DNS) |
| Security | ⚠️ Low | ✅ High |
| Speed | Faster | Slightly slower |
| 2025 Recommendation | ❌ Obsolete | ✅ Use |
Example SOCKS5 Configuration:
# Curl with SOCKS5
curl --socks5 proxy.example.com:1080 https://example.com
# With authentication
curl --socks5 username:password@proxy:1080 https://example.com
# SSH via SOCKS5
ssh -o ProxyCommand='nc -x proxy:1080 %h %p' user@server
# Git via SOCKS5
git config --global http.proxy 'socks5://proxy:1080'
🎯 How to Choose the Right Port
Port Selection Flowchart
❓ Need maximum stealth and block bypassing?
→ Use port 443 (HTTPS)
Reason: Traffic looks like regular HTTPS; firewalls do not block it, and DPI has difficulty detecting the proxy.
❓ Only need HTTP traffic (web scraping, browsers)?
→ Use port 8080 (HTTP)
Reason: Standard for HTTP proxies, wide support, no root required.
❓ Need torrents, gaming, P2P, UDP?
→ Use port 1080 (SOCKS5)
Reason: Universal protocol, UDP support, works with any traffic type.
❓ Corporate network with Squid?
→ Use port 3128 (Squid)
Reason: Standard for Squid proxies, caching, access control.
❓ Standard ports blocked?
→ Use non-standard ports (10000+)
Reason: Firewalls usually only block known ports; non-standard ones often pass through.
🔐 Proxy Port Security
Security Recommendations for 2025
🚨 Dangerous Practices:
- Open proxies without authentication — can be used for attacks
- Using only IP whitelist on public IPs — the IP can be spoofed
- HTTP proxies without TLS — data is transmitted in clear text
- Weak passwords — easily guessed by bots
- Ports with known vulnerabilities — old software versions
✅ Safe Practices:
- Always use authentication — username/password or IP whitelist
- HTTPS on port 443 — traffic encryption via SSL/TLS
- Firewall rules — restrict access at the port level
- Rate limiting — protection against DDoS and brute force
- Log monitoring — track suspicious activity
- Regular updates — patch vulnerabilities
- Port rotation — use non-standard ports for stealth
Securing Ports with iptables
Allow access only from a specific IP:
# Allow access to port 8080 only from 192.168.1.100
iptables -A INPUT -p tcp --dport 8080 -s 192.168.1.100 -j ACCEPT
iptables -A INPUT -p tcp --dport 8080 -j DROP
# Allow access to SOCKS5 port 1080 from a subnet
iptables -A INPUT -p tcp --dport 1080 -s 10.0.0.0/24 -j ACCEPT
iptables -A INPUT -p tcp --dport 1080 -j DROP
Rate limiting (brute force protection):
# Limit to 10 connections per minute on port 8080
iptables -A INPUT -p tcp --dport 8080 -m state --state NEW -m recent --set
iptables -A INPUT -p tcp --dport 8080 -m state --state NEW -m recent --update --seconds 60 --hitcount 10 -j DROP
🚧 Blocked Ports and Bypassing Methods
Why Ports Get Blocked
Many corporate networks, ISPs, and countries block specific ports for traffic control, security, or censorship.
Frequently Blocked Ports:
| Port | Protocol | Reason for Blocking |
|---|---|---|
| 8080 | HTTP Proxy | Known proxy port, blocked by firewalls |
| 3128 | Squid | Standard Squid port, easily detected |
| 1080 | SOCKS | Used for bypassing blocks |
| 9050 | Tor | Tor SOCKS port, blocked in censored countries |
| 25 | SMTP | Spam prevention |
Methods for Bypassing Port Blocks
1️⃣ Using Port 443 (HTTPS)
Effectiveness: 95% — Port 443 is rarely blocked as it is the standard for HTTPS. The traffic looks like regular web traffic.
proxy.example.com:443
2️⃣ Non-standard High Ports (10000+)
Effectiveness: 80% — Firewalls usually only block known ports. High ports are often missed.
proxy.example.com:12345
proxy.example.com:40000
3️⃣ Port Hopping
Effectiveness: 70% — Periodically change the port to avoid being blacklisted.
4️⃣ Tunneling via SSH (Port 22)
Effectiveness: 90% — SSH port 22 is usually open. Create a SOCKS tunnel via SSH.
ssh -D 1080 -N user@proxy.example.com
🔄 Port Forwarding for Proxy Servers
What is Port Forwarding
Port Forwarding is a NAT (Network Address Translation) technique that redirects network traffic from a specific port on an external IP address to an internal IP address and port on a local network.
🎯 Why it is needed for proxies:
Scenario: You have a proxy server on your local network behind a router with NAT. You want clients from the internet to be able to connect to your proxy.
Internet → Router (Public IP: 203.0.113.1)
↓ Port Forward: 8080 → 192.168.1.100:8080
Local Network → Proxy Server (192.168.1.100:8080)
Clients connect to 203.0.113.1:8080, and the router redirects the traffic to 192.168.1.100:8080
Setting Up Port Forwarding on the Router
📋 Step-by-step instructions:
- Open the router's web interface — usually
192.168.1.1or192.168.0.1 - Log in with administrator credentials
- Find the section "Port Forwarding", "Virtual Server", or "NAT"
- Create a new rule:
- Service Name: Proxy Server
- External Port: 8080 (port from the internet)
- Internal IP: 192.168.1.100 (Proxy server IP)
- Internal Port: 8080 (Port on the proxy server)
- Protocol: TCP (for HTTP/SOCKS)
- Apply settings and restart the router
Examples for popular proxy ports:
# HTTP proxy on port 8080
External: 8080/TCP → Internal: 192.168.1.100:8080
# HTTPS proxy on port 443
External: 443/TCP → Internal: 192.168.1.100:443
# SOCKS5 on port 1080
External: 1080/TCP → Internal: 192.168.1.100:1080
# Squid on port 3128
External: 3128/TCP → Internal: 192.168.1.100:3128
Port Forwarding via Command Line
Linux (iptables):
# Enable IP forwarding
echo 1 > /proc/sys/net/ipv4/ip_forward
# Forward port 8080 to internal server 192.168.1.100:8080
iptables -t nat -A PREROUTING -p tcp --dport 8080 -j DNAT --to-destination 192.168.1.100:8080
iptables -t nat -A POSTROUTING -p tcp -d 192.168.1.100 --dport 8080 -j MASQUERADE
# Save rules
iptables-save > /etc/iptables/rules.v4
Windows (netsh):
# Forward port 8080 to 192.168.1.100:8080
netsh interface portproxy add v4tov4 listenport=8080 listenaddress=0.0.0.0 connectport=8080 connectaddress=192.168.1.100
# Show all forwards
netsh interface portproxy show all
# Delete forward
netsh interface portproxy delete v4tov4 listenport=8080 listenaddress=0.0.0.0
⚠️ Port Forwarding Security Risks:
- Open ports — attackers can scan and exploit vulnerabilities
- DDoS attacks — direct access to the server from the internet
- Brute-force attacks — guessing proxy passwords
- Exploitation — using the proxy for illegal activities
Solution: Always use authentication, firewall rules, and traffic monitoring!
🛡️ Firewall Rule Configuration
Basic Firewall Principles for Proxies
🎯 Principle of Least Privilege:
- Block everything by default (default deny)
- Allow only necessary ports

🌐 NAT Configuration
Types of NAT and Their Impact on Proxies
| NAT Type | Description | For Proxies |
|---|---|---|
| Full Cone NAT | Any external host can send packets to the internal IP | ✅ Excellent |
| Restricted Cone NAT | Only hosts to which the internal host has sent packets | ✅ Good |
| Port Restricted Cone NAT | Additionally checks the source port | ⚠️ Acceptable |
| Symmetric NAT | Every request to a new host gets a new port | ❌ Problems |
SNAT and DNAT Configuration
SNAT (Source NAT) — changing the source address:
# Proxy server behind NAT: change source IP to external IP
iptables -t nat -A POSTROUTING -o eth0 -j SNAT --to-source 203.0.113.1
# Or use MASQUERADE for dynamic IPs
iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE
DNAT (Destination NAT) — redirecting incoming traffic:
# Redirect incoming traffic to the internal proxy
iptables -t nat -A PREROUTING -p tcp --dport 8080 -j DNAT --to-destination 192.168.1.100:8080
# For multiple ports
iptables -t nat -A PREROUTING -p tcp --dport 8080:8089 -j DNAT --to-destination 192.168.1.100
🔧 Troubleshooting Port Issues
Typical Problems and Solutions
❌ Problem 1: Cannot connect to the proxy
Possible Causes:
- Port closed by firewall
- Proxy server is not running
- Incorrect IP or port
- Port forwarding is not configured
- Port blocked by ISP
✅ Solutions:
# 1. Check if the proxy is listening on the port
netstat -tulpn | grep 8080
ss -tulpn | grep 8080
# 2. Check the firewall
sudo iptables -L -n | grep 8080
sudo ufw status
# 3. Check external port accessibility
telnet your-server-ip 8080
nc -zv your-server-ip 8080
# 4. Check proxy logs
tail -f /var/log/squid/access.log
❌ Problem 2: Port already in use (Address already in use)
✅ Solution:
# Find the process using the port
sudo lsof -i :8080
sudo netstat -tulpn | grep :8080
# Kill the process
sudo kill -9 PID
# Or change the proxy port to a free one
sudo nano /etc/squid/squid.conf
# Change: http_port 8080 → http_port 8081
❌ Problem 3: Slow speed through the proxy
Possible Causes:
- High server load
- Insufficient bandwidth
- Many concurrent connections
- Slow DNS resolution
✅ Solutions:
- Increase connection limits in the proxy config
- Optimize TCP parameters:
tcp_window_size - Use DNS caching
- Enable keep-alive connections
- Distribute load across multiple ports/servers
