Bypass ISP blocking for port 6667 (without VPN)

In my country (Malaysia) there several port get block permanently, such as 445, 6667, 27005. I believe some player facing same issue like me.

Internet Service Provider (ISP) block port 6667 due to "safety reasons". Port 6667 TCP used by Internet Relay Chat (IRC). Red Alert 3 use this port for chatting in game.

I made a post in Revora Forum[forums.revora.net], at the end I able to solve without need a VPN.

Test Connection

Open a Windows PowerShell console and paste this, check if your ISP do block port 6667 or not.

Test-NetConnection peerchat.server.cnc-online.net -port 6667

If you results come with:

TcpTestSucceeded       : False

Mean your ISP is blocking port 6667.

Start Unblocking

Since only port 6667 get blocked, it's time to redirect by using proxy
In this tutorial, I using Proxifier software[www.proxifier.com] (trial, paid, tested). You can choose alternate free software such as WideCap[widecap.com]

Proxy Server

In this guide, we going to use SOCKS5 proxy server, either you can find on the Internet or create own proxy server.

It's better to use SOCKS5, since it support to proxy a UDP connection, just in case.

Proxifier

Download & Install

• Download and Install Proxifier[www.proxifier.com].
  I recommend using portable version since we going to use for Red Alert 3 only.
  
• Launch "Proxifier.exe"
  

Add Proxy

• Open Proxy Servers window (ALT+P, P)
  
  
• Add proxy server or own proxy server
  
  
• Click "Check" button to test proxy server.
  
  
• If selected proxy server is working, close Proxy Checker and Click OK.
  
• Click "No" if this message popup. We want other connection use direct
  

Proxification Rules

Once you have working proxy server, now we can proceed to add rules for port 6667

• Open Proxification Rules window (ALT+P, R)
  
  
• Click "Add" button
  
• Follow:
  

  Name: IRC
  Application: *leave blank* Any
  Target Hosts: *leave blank* Any
  Target Ports: 6667
  Action: Proxy SOCKS5 ...
  

  
  
• Click OK and make sure it look like this:
  
  Default and Localhost using "Direct" Action

Test Proxy

Run Red Alert 3 via Revora and Login.
You can check Log if port redirection is successful.

If you want to see full log, set this

Troubleshoot

Not all public proxy server accept traffic other than 80 (HTTP) or 443 (HTTPS/SSL). Keep testing until you find one. If you dont find one, it's time to create own proxy server.

One more thing... Red Alert 3 connectivity very limited.
Red Alert 3 only can be run under one Router per Public IPv4 Address, if you try co-op in same house/router/public IPv4 address, trick is one of you need use VPN :( You can share 6667 proxy server.

Host own proxy server

Public proxy sometime vanished or unstable, good way is to rent cheap VPS hosting, DigitalOcean or Vultr or any VPS hosting near you

This guide will skip everything, once you have SSH console ready, follow this step:

Install Dante

I using Dante SOCKS5 Proxy server, it's fast even on low spec VPS
BitTorrent works too!

• You need install some development tool like GCC
  

  apt-get install build-essential zlib1g-dev libwrap0-dev screen nano wget git unzip htop iptraf uml-utilities

• Download Dante source code
  

  wget https://www.inet.no/dante/files/dante-1.4.2.tar.gz

• Start configure and compiling...
  

  tar -zxvf dante-1.4.2.tar.gz
  cd dante-1.4.2
  ./configure
  make
  

• If you want to install run:
  

  make install

Dante Configuration

Here some basic configuration file

• Make a blank conf file
  

  nano ~/dante.conf

• Paste this config code
  You may need to change "ens3" to "eth0" or else, check it via "ifconfig"
  

  logoutput: /var/log/sockd.log
  
  #server address specification
  internal: 0.0.0.0 port = 4380
  external: ens3
  
  user.notprivileged: nobody
  
  clientmethod: none
  socksmethod: none
  
  client pass {
          from: 0.0.0.0/0 to: 0.0.0.0/0
  	    log: error connect disconnect
  }
  
  socks pass {  
          from: 0.0.0.0/0 to: 0.0.0.0/0
          command: bind connect udpassociate
          log: error connect disconnect iooperation
  }
  
  socks pass {
          from: 0.0.0.0/0 to: 0.0.0.0/0
          command: bindreply udpreply
          log: error connect disconnect iooperation
  }
  

• Run Dante
  That "&" will execute command line without blocking
  

  ~/dante-1.4.2/sockd/sockd -f ~/dante.conf &
  

Have Fun!

Sorry for my bad english...

I don't need this, but I love seeing people get around these sort of restrictions. GJ with the guide! 👍

Proxy?

[Mura J]

Doesn't that leave the system vulnerable?

[publicENEMY]

"Add proxy server or own proxy server" Where can I get free proxy server? How do I create own proxy server? What is the requirement to create a proxy server?(must be outside Malaysia? since Malaysia blocked port 6667)

[publicENEMY]

Is widecap truly free to properly use?
