    I need to connect two devices on a router with the same IP. One is through wired one is through WiFi. How can i do this? I know it can be done.

    Two devices to the same router, and you want both devices to have the same IP? Are you sure it can be done.. ? I don't think so.. even if one is ethernet, and the other WiFi, both are using the same protocol, and I think a conflict would be there..

    Well, on another forum the guy said i had to to do what i want.... complicated, but here it is.

    I need to do something on my ipod touch and i need to use WinSCP to get into the ipod's files and stuff. To do it, both the PC and ipod has to have the same IP. I also read on a goog search something about using the mask or something to do it.

    Did you ask this guy on the other forum how to go about doing what he told you you had to do? If the deal involves playing around with the subnet mask, then perhaps you should also start by learning a little something about subnetting and using subnet masks, e.g., from this Wikipedia article.

    I own an iPod Touch too... if you need to access the files using WinSCP, you can just use a wireless router to assign local IP addresses to both devices and then access it locally.
    Also you can just set up internet sharing with a wired internet connection on the laptop, plus have the wireless set up so that the iPod can access the internet as well.

    I'm not sure why you would ever need to have it use the same IP address, because that seems pretty impractical/impossible.

    You can do port forwarding, this way you can use the same IP address.

    @Nvidia: perhaps you should pm Surfer666, who seems to know what you're talking about and could probably give you the most help here.

    Port forwarding will do!

    Your only allowed 1 IP on a network. Duplicate IP will raise havic and may bring the local network down. I had a user where I worked randomly assigned a static IP to his NB, just happened to be one that was already assigned to computer in the security command center. WAS NOT PRETTY. This set caused all kind of problems. We we able to trace and find him real quick. He ended up on the red carpet over it.

    On a local network there is no reason to have the same IP address. The router will handle the NAT function and routing to the correct device.

    Yes, but if he seprate both devices using two tunnels, two diffferent ports then he will be ok, don't you agree?

    If this is a Apple requirement they (Apple) should have a procedure.

    Ha ha! Same thing happened at a place I used to work. A co-worker in our IT department changed the IP address on his workstation for testing purposes and inadvertendly set it to 172.x.x.1 (he meant to set it to 10 or something). Of course, that .1 address was the address for the BIG HOG UNIX SERVER THAT RAN DNS FOR THE WHOLE COMPANY! Two thousand workstations and countless servers ground to an immediate halt. It took 10 minutes (during which we were in a state of extreme panic) before it occurred to the guy that maybe he'd done something...like, uh, maybe fat-fingered his IP address. Dude never lived it down.

    Funny today. Wasn't funny then.

    Port forwarding will not solve the issue. Port forwarding just means if the router gets a packet at said port, it forwards the packet to a certain IP address.

    Yeah, setting two different computers to the same IP address will confuse the router.

    HAHA. This is hilarious.

    May be funny now but it was not at the time. It just confirms you do not want to devices with the same IP address. Lucky for me is that all of my card access went into stand along mode, but had no means to over ride while it was down.

    It is possible, here there is the port forwarding and another simpler way to do it, using the same MAC address.

    The port forwarding isn't related to this thread. Port forwarding has more to do with Network address translation.

    But I like that one dude's comment on the second link. He cloned the MAC address on another computer on his network. Interesting. I would think that would throttle your bandwidth since have two computers with the same MAC address theoretically increases your chances of collisions.

    does WinSCP work like the scp command from the ssh suite? if so, then you should simply need to know the IP assigned to the remote device, assuming that you can run an ssh host on the iPod... ?
