Will forwarding ports be dangerous?

A Forum Thread for GameBanana

I need to forward some ports for a CS 1.6 dedicated server...

I'm creating a dedicated server for Counter Strike 1.6, and I need to forward some ports. Will this create a greater chance of virus's or other harmfull things? I'm not good with this kind of stuff thats why I'm asking.

    Viruses? No, that pretty much depends on how you use your computer, but not entirely. It can open you up to intruders, though. Normally, those ports would be filtered. That's neither open nor closed. An open port would allow connections over it and would also tell an intruder it does that. A closed port would simply respond saying it will not accept connections. Neither is secure, in my opinion. What you currently have is probably a filtered port, which most likely does not respond to any requests. As far as an intruder is concerned, your computer does not exist, if the ports are filtered. By opening the port(s), you're allowing connections and telling everyone that you're there and waiting for requests. It will also not likely second guess any data sent to it. So yes, you're less secure, At which point, your network security depends on the system that data is being porwarded to. If it's a Linux server, there's no worries. If it's a Windows server, just take whatever precautions you need.

    So if I open up these ports that I need for a 1.6 dedicated server, is it easier to get virus's from Internet Explorer or Mozilla Firefox?

    No, it's easier for an outside entity to find your computer and penetrate your defenses. The ports being open have nothing to do with getting infected by web surfing.

    That's hard to say. Well, Internet Explorer is vulnerable in any situation, but opening a port isn't going to help. And it's not really the viruses you should worry about here. It's other people that will target you. All I'm saying is that it will open you up, but you're not exactly vulnerable.

    But these ports, theres like six of them...does that mean it is only easier to be "penetrated by outside entities" through Counter Strike? Or its just easier for other entities to find my computer?

    It won't be through Counter strike, it will be programs written to ping random IPs and ports to see if there is a computer there. By opening ports the program will know there is a computer there, and may begin trying to penetrate your system via whatever vulnerabilities it has been configured to attack.

    So pretty much I have to be secure and stop watching porn to lower the risk of being attacked?

    Nothing to do with surfing the web/watching porn etc... You can leave the computer there and the hacker can still try to get into your system whether you watch porn or not.

    Opening a port will statistically make you more vulnerable, yes.
