    I have a Linksys Cable Router BEFSR41 V.2
    I want my friends to be able to connect to my public folder to share files and stuff easily. I can connect to them, but they cant connect to me. I have tried messing with the settings in the router, but I am not getting anywhere. Can somebody help me please?:confused: :confused:

    I run OSX

    make sure in your system prefs that everyones sharing and everything is turned on...and apple talk to...and make sure its not on firewall mode. not sure specifically which of these prefs do it but just turn them all on and it should work ok.

    i have done all that, I think that it is the router with the firewall, and it cant be disabled.

    Or, would my freinds have to use a different ip than what the router gave me? Would they have to use that ip address and then mine?

    Your router is probably using NAT. So, your Internet provider gives you a real, globally routable IP address. Your router than gives you a private IP address:

    172.x.x.x (there are 172. addrs that are real, but I doubt your provider has one)

    Your router than does some magic and translates your private IP address into the routers real address. This lets you share that one IP addr that your provider gives you with a bunch of other computers.

    Your solution will involve port mapping. You will need to see which port your file sharing is using. Go into the:
    Control Panel -> Sharing -> Firewall, and look at the numbers that are next to the services. What you want to do is look at your firewall configuration (probably a web page) look for something like "port mapping" and then tell it to map the port numbers next to the service in the firewall control panel to the IP address that your computer is using. Look in the network control panel to find out what it is.

    Manually setting your IP address will only mess things up, and will NOT fix your problem. Your router is giving you a reasonable address, if you are going to use a router.

    I am assuming that you have a reason to use a router in the first place. If you only have one computer, you don't need it, unless you are using wireless and airport, since apple stupidly does not allow you to make pppoe connections over airport, and most ISPs require pppoe for broadband.

    Hope this helps

    i have the same router, never had this problem! i did however have a similar problem with a pc on this router - turned out to be the cable, if one strand dies, you can lose some networking aspects but not others. I.e. - we had a computer that was on the network, filesharing was fine but it would not get online. We bought a new cable and all was fine. I also have 2 other cables - one won't work on a pc (network card doesn't even recognise it as a cable being connected) but works fine on my mac and the other wont work on a mac but does on the pc! It took me days to figure it out! Very strange. Wifi is the way to go methinks!
