IP addressing, technical information please....

How does this program connect peers? I have used Hamachi and it is very easy. The only part I do not really like is that you need to connect to thier servers to get connected to your peers. Your terminology states that one user becomes the 'server' so to speak, and that other peers connect to that 'servers' vpn. That is simplified, but you get the picuture. In hamachi, once you create a network, anyone with permission can join, regardless of whether you are on or not. So how does this compare in that respect?

Also, what can you give me about the ip addresses? Hamachi assigns an ip internal to them I think. Often in XP you can see the vNic become enabled and see a connectivity issue that gives a 'partial connectvity' icon in the tray. I have found that by writing to the registry in the corresponding reg key the ip hamachi assigns you (which seems permanent), you effectively create a static ip for the vNic which solves the 'partial connectivity' issue.

What are the ip addresses that could be used? Why? Do they change?

I have made rules for my firewall with hamachi, so that I can still have a firewall up and also use hamachi. I don't want to just blanket allow it. Do you have any information as to what ports and remote addresses will be expected?

In short, I am always looking at new tools, and have tried yours on vmWare. But I am wondering more about the technical addressing side. My friends and I use hamachi to play games mostly. LAN style. Especially games that have coop in them or might not be great or have any online portions with the same effect. I have found that hamachi is not so great for use as file sharing. It has upload issues, perhaps due to settings in the vNic. We use primarly free file storage services for most of that. What can you tell me about those same issues regarding your program?

Many questions.

Thank you.

    MrWoo,

    Let me see if I can get around to all your questions here. Please feel free to ask again if you need further clarification.

    How LAN Bridger connects peers:

    LAN Bridger is completely decentralized. Unlike Hamachi, you don't need to use our central server to connect to your friends' networks. Instead, the network profile that gets generated when the network is created is the 'key', so to speak, for people connecting to your network. The network profile contains information about the location of the master, i.e. your LAN Bridger server, and other things used to ensure that a secure connection can be established. In other words, you can host your own network without ever interacting with our server. This also means your network will continue to work even if we have an outtage (fingers crossed).
    Since networks are always password-protected, only people who have the network profile and who know the password can join your LAN Bridger network. Also, since the network is never registered at our servers, nobody can find your network without having the network profile. This gives you extra security if you want to run in private ("stealth") mode.

    How LAN Bridger deals with IP addresses:

    The IP range that Hamachi uses is essentially a reserved range that nobody should be using. For LAN traffic, three segments have been allocated that you might have seen before:

    • 10.0.0.0/8

    • 192.168.0.0/16

    • 172.16.0.0/12


    These special ranges are also documented here: http://en.wikipedia.org/wiki/Classful...

    Since Hamachi uses a non-standard private IP address range, some applications (including many games) don't work correctly because they expect to be operating on a real LAN segment.
    LAN Bridger, on the other hand, allows you to set up the IP range you wish to use for your network. The person who hosts the LAN Bridger network can configure this in the Network Settings dialog. By default, the IP address range used on your LAN Bridger network changes every time you host the network. You can change this behavior in the Network Settings dialog as well.

    On a final note, if you want to go the Hamachi route, you can still assign the same kind of 5.x.x.x addresses that it uses, but I strongly advise against it.

    Ports in use by LAN Bridger:

    By default, LAN Bridger uses port 40001 when you host a network. You can change this either in the Host Network wizard, or at a later time in the Network Settings dialog once you have hosted the network. Just remember to send your friends an updated copy of the network profile if you've made such changes. In the future, we'll make it a lot easier to pass around these profiles, but that's work in progress.

    Games

    As I've already mentioned before, LAN Bridger has better support for games than Hamachi since it emulates a real LAN network with real private IP addresses. LAN Bridger also handles broadcast traffic much better than Hamachi. This is important when you play e.g. LAN games and you need to search for a local server. This behavior is, frankly, very flaky in Hamachi.

    File Sharing

    If you want to share files with your friends on your LAN Bridger network, you can use several mechanisms. Personally, I simply use Windows file sharing for small files and FTP for everything else. Rest assured that LAN Bridger will provide built-in support for file sharing at some point.

    LAN Bridger is still in its very early stages and there's much room for improvement. We're getting there, though, and I hope you'll stay with us for the ride!
