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 🙂
