To get your wonderful game hosted on your uber-speed connection, you'll need to port-forward.What does that mean?
Everything has a 'port' or designated number it uses to connect, every port sends different data, because different programs use different ports, or else you would get your game connections sent to your internet browser. When you 'forward' a port, the router passes the infomation through the network like a normal connection. For example, port 80 is for internet browsing, and port 25 is for emails. Since these ports are both used for common tasks, people will try to attack you through it. That is why ports 80 and 25 are the most heavily defended, most commonly blocked ports. This is why people have firewalls and anti-virus programs with online defences.What about security risks?
It's only a connection into your network, unless you have a program recieving the information, it's useless. If you think this is a massive security risk, let's take a look at Hamachi. Hamachi opens many ports, that's why it works for many programs. It also means people can activate almost ANY programs on your computer that are active, posing a MASSIVE security risk.
If you DO need to use a VPN program, Tunngle and Evolve use game-lobbies, only opening the ports used by the game. It's safer and simpler, and the security risk is no more dangerous than regularly browsing the internet.How do I do it?Do not download PortForward.com's software to auto port-forward. It is bundled with adware.Here[portforward.com]
you will be taken to a guide on how to port-forward your router. Find the manufacturer on the router, and find the model, usually printed on a label or the box. Once you have entered your model number, look for the game 'Half-Life: Steam', and follow the website's guide.
If you do not port-forward or cannot, your match will NOT show up on the game-monitor lists, and you WILL have to use Hamachi or another VPN (Virtual-Private-Networking) Service.If you did not port-forward, please read the paragraph about security risks.I highly recommend that you stop using Hamachi. Tunngle has game-lobbies, which are safer and support up to 256 people, although you can't make your own networks.
