I have a Tikona Digital Broadband (WiMax based) Internet Connection which allows limited number of devices to be connected at a time and also requires that the users login with username and password (by visiting a browser page on each device) before beginning to browse Internet.
If more than the allowed number of devices are to be used, some of the previous devices must be removed from their portal. They track these devices using MAC addresses.
Physically they have a wireless device at the roof of my building which has a CAT5 cable running to a powered device in my room. Another CAT5 cable from this powered device will connect to my Laptop or wireless router.
I have a Beetel 450TC1 ADSL + Wireless router from my previous connection which I am currently using in Bridge mode to be able to browse wirelessly. Router's DHCP is also disabled and my devices get IPs assigned by the ISP's devices directly.
I have these problems/questions:
1) Each device needs to enter a username and password using a browser which limits some of the devices like backup devices, personal cloud device, media servers, download boxes etc from being able to connect to Internet as they don't have a browser.
2) Since these devices get IP from the ISP I am not able to access them from my laptop as its not a static ip and no way of finding out what was assigned to these headless devices.
3) How can I have my current router (or a new one) to be able to login to the ISP's page automatically on powering, maintain a local IP pool for my devices and laptop which can then access Internet through my router spoofing the MAC addresses ?
