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 &
