Recently, we got a WiFi router. We got that working. But there is a problem. Our university provides every individual with user login IDs and passwords. We can't access any website which is not on our university's server without authenticating with these credentials. And that router is working on a LAN connection provided to me by my university in my room with a static IP address. If We use multiple devices on this router, it asks for authentication from only one of them. Since, our data usage is tracked(No, it isn't. I'm just curious about how to do this), none of us were ready to login on the router(No one wants their data usage to be unusually high). So, is there any way I could set it up so that rather than allocating different local addresses to all the devices, it allocates different public addresses to all of them? I've a range of IP address which we get allocated whenever we connect to some router which belongs to my university.

  • Your university is only going to assigned the router a single ip address. Getting the router assigned multiple LAN addresses won't be possible given the configuration of the university's network.

  • Well, technically it's possible, but needs some manual setup by the network admins. Apr 20, 2016 at 13:36

    @Paul: Nah, sounds more like they don't expect multiple users to share an IP address, but OP ended up doing that anyway, by buying and connecting a home router with NAT to the network. In which case it would be best to reconfigure the router device to "bridge mode" instead. Apr 20, 2016 at 13:37

    @AyushTulsyan The routers that the sysadmins are in control of work exactly the same way as any other router. They are just configured by the sys admins to provide more than one IP address (as is the router that your router connects to). There is no magic there, and as pointed out, the admins would need to provide this to you, you cannot do it yourself.

    You might be able to put the router in bridge mode and turn off DHCP but I doubt it... as is the theme of all these comments, it depends on choices the university admins have made.
