BSNL WA3002G4 for relaince wimax

[thesaint2]

Hi Guys,I like to know if this is possible. I already have a BSNL broadband and have bought relaince wi-max, i will be using both broadbands for my work.I have a 4 lan port, 1 RJ11 wan port WA3002G4 modem/router from BSNL and i want to utilize this for relaince wimax as well.I like to know how can i setup relaince wimax using the router present in the modem.I know that the 4 RJ45 ports are LAN, is there any way to convert them into a WAN port simulator using the settings in the control panel.If yes, then i can set up static IP over the LAN and bridge to my LAN.Can you guys give me some ideas on how this can be done. Or i have to buy a router??😛thanks in advance😛
