Hi!

I am aware of software out there that enables you to "LAN" over the internet with your buddy somewhere else. Being capped now i have 30gigs to waste somehow. I was wondering if there is a app that could make "LAN" possible with my friend over the internet.

Since i should be able to connect locally to him, i just need something that will let us "LAN" over the internet and doesn't pass through some international server first.

And if at all possible can you give me applications that i can download locally? or if you feel really generous host it locally for me :D

P.S it's meant for Left 4 Dead 2 so it must be able to support games.

Thank you so much!
 
Any VPN would do, be it Microsoft PPTP VPN, OpenVPN, L2TP or Hamachi.

Hamachi would definitely be the easiest to use and you don't have to know the other person's IP address. Unfortunately for you, you won't be able to use it since you don't have cap left and Hamachi has to connect to an international server first.

If you're only 2 persons wanting to "LAN" over the Internet, then Microsoft's PPTP VPN server would do just fine if you're running Windows XP Pro or Windows 7. Windows XP allowed only 1 client to connect at once, but I'm not sure about Windows 7.

So I would recommend to use something like OpenVPN if you want more than 2 clients to connect to the VPN server. If the person hosting the VPN server has international cap left, he/she can share their Internet connection for the VPN clients to use, but its not required to do that :)
The OpenVPN option has another advantage, since it can be run as a service which automatically hosts the VPN server and the clients can also set it up as a service to automatically connect to the VPN server, unlike Microsoft's PPTP VPN. OpenVPN would also allow you to dial PPPoE connections via the VPN, where PPTP/L2TP/IPSec won't allow you to do that!
Here are a few useful links for setting up VPN's:

wow what a mouth full of abbreviations! :D but thank you for your very informative response! will take a look into it. My friend has uncapped internet so it shouldn't be a problem. but thanks again!
 
Remember your speeds are only as fast as the slowest upload.. connect to a wug in your area rather.

Not so fast.

You need a VPN that can tunnel UDP, which most don't/can't be default. Hamachi does, but to use it you'd need to be able to access their STUN-like servers. If its IS local only then you can try anyway since IS local lets through small amounts of intl traffic to allow acces to intl auth servers.

UDP functionality is mainly required for the LAN lobby in the game i.e. to join, but some games themselves require UDP for the game itself.

The IP addr thing isn't an issue. You can just use a *local* dynamic IP service like dyndns.co.za

All of the VPN's that I mentioned are capable of transporting TCP and UDP! I think you're mixing proxy servers with VPN services :) Like HTTP proxies can't forward UDP packets, where as Socks 4/5 proxies can.
When you're making use of a proxy server, then you can't be considered to be on the same LAN, where as VPNs give you "LAN" access.

If the game allow you to specify a destination IP address for the server, then you don't require a VPN but you would still have to port forward.
If the game has a LAN game/lobby facility, like Warcraft III / Starcraft, and it doesn't allow you to specify a server IP address, then you HAVE TO make use of a VPN. The game discovery use UDP broadcasts to discover the games on the LAN.
For the game discovery to work, every person has to change their network interface order such that the VPN interface is used first, otherwise the broadcasts would be sent out on the wrong interface. Here are instructions on how to achieve that in Windows Vista/7: http://www.windowsreference.com/windows-vista/change-network-adapter-priority-in-vista/

eh, sorry for not being clear. I was objecting to your "Any VPN would do" comment because of this:

OpenVPN offers two types of interfaces for networking via the Universal TUN/TAP driver. It can create either a layer-3 based IP tunnel (TUN), or a layer-2 based Ethernet TAP that can carry any type of Ethernet traffic.

For the UDP lobby to work it needs a TAP interface.

er... NO.

UDP is a layer-4 protocol - it will run on top of both TUN and TAP interfaces.

I'm not sure where you got your info from but I can say that a VPN that couldn't support UDP would be pretty useless cause you wouldn't be able to even do dns lookups ;)

Too lazy to google this now, but basically the UDP broadcasts you need for the lobby won't jump subnets, so you need bridging via a TAP interface. Either that or I'm just a bit lost.

Ok.... now we getting there. Broadcast traffic is on layer-2 so you need a layer-2 bridge between the locations to allow the broadcasts to reach all the hosts. This has nothing to do however with it being UDP or any other kind of layer-4 protocol :p

Basically you require a bridged network and not a routed one.
 
@ambo, thanks for the explanation :)

@penguin: nice suggestion. I've never heard about it, but it seems pretty cool for noobies to use.
 
i have no more brain left!i have absolutely no idea what you guys are talking about now :) but feel free to continue :P
Going to try out LAN Bridger, seems much more simpler than all the complicated stuff mentioned above :D
