Getting around firewalls...

[SlingBlade]

Hey, I'm behind a firewall that has the ports certain games use blocked. I don't have access t othe firewall of course. I was wondering if there is any ways around that? Can I change what ports the game uses. or try other things?

Yahh. This is a network problem. Yaaahh. I have a case of the mondays.

Here's the software answer in the hardware forum

If they don't block Virtual Private Networking, you can use the VPN "Device" as your connection around the firewall.
Basically, VPN networks with another network through a network (In this case, the Internet).
You can then get online through that network.
My cable company has something misconfigured so that I can lease as many IP addresses as I need, so I'm attempting to set up a VPN server for this purpose.
You will need Windows2000 Server or dedicated hardware server equipment to set one up, and Windows98 & above have VPN clients built-in...
I'm still working this out step-by-step, so I can't really help out any more than this (yet).

Or you could also use a program like HTTPort and set up to connect through everything through a proxy. The two drawbacks are that 1) the speed is not that great.. pretty slow actually, we're talking like 1-2 KB/sec, and 2) it's kind of hard to set up because you have to creat a port mapping for every program that you want to use or every server you want to connect to. Also, it doesn't work on absolutely everything, but it will definitely be a lot better than where you are at right now. And it's free, so...

The vpn answer was awesome, but you dont even need Windows for it

Also, you could setup a proxy and try to use that. Granted, you will have to pay for the proxy (unless you crack a wingate, but that is a BAD THING TO DO), but you will be able to play your games

Thnx! I still have yet to try it, so I can't say I know what I'm talking about.

It's probably possible to block external proxies if the network is using NAT (Like it is here), but it sounds like a possible solution
Most filtering networks filter using proxy servers & probably try to prevent the use of any other proxy

<< Thnx! I still have yet to try it, so I can't say I know what I'm talking about. It's probably possible to block external proxies, especially if the sites he's trying to access are blocked by a proxy + NAT server (Like it is here), but it sounds like a possible solution >>



I have never used a vpn to play games, but Im sure it would work, and it would essentially be another type of proxy.

Well, because VPN uses a virtual networking "device" if it can tunnel to a VPN server it can be a free & open direct Internet connection. Your system will see 2 different devices that it is capable of connecting to the Internet with. Of course, they could block VPN, but most companies USE VPN

An example of it being used for a real "unhindered" (Or proxied) Internet connection is my friend's cable ISP.
His cable company puts everyone behind a NAT server & firewall (I guess to avoid the "cable is a security risk" argument), but this of course means problems connecting to other users on the Internet (Especially with filesharing & messaging applications). To solve this, they offer the "power users" (Actually, I'd say "Anyone who doesn't only use the Internet only for Web & email" users) the ability to tunnel through using VPN & get a real Internet IP address (As opposed to using a network address w/ NAT) for an extra $5 a month. The only drawback is apps that can't decide what connection to use & if you set VPN to default, you run into other problems (Like the VPN "Dialer" launching in the middle of Quake3 because you listed multiplayer servers & Quake3 crashes when being forced from full-screen in most cases). There's no hassle-free way to do anything I guess

Thanks! Sorry for posting in the wrong forums. I'll repost it in networking
